ZLIN SAVAGE NORDEN
The constant speed with Norden
Very nice and clear running,No vibration, the RPM always same. I tested up and down, max speed, max power, same RPM.
The performance is better az E-prop 4 bld fixed (also good prop).
Climbing and take off both props close same, but cruise speed is 15 km/h faster.
I fly 4800 RPM and 20 liter per hr 175 km/h....same speed 4 bld needs 24-25 liters per hr.
If can be constant bigger ( 200 cm), will stronger for stol plane

JMB AIRCRAFT VL3 EVOLUTION
Finally I found the perfect propeller for my VL3!
This Glorieuse propeller is simply a marvel of engineering; a careful design - it seems that it took the designer 5 years, but we understand why! - an incredible lightness and solidity - see the tests, it's very telling - and a piloting comfort like I never had. The fuel consumption is down, the performance is up, in any case I'm more than satisfied.
Long life to the Glorieuse!

EXCALIBUR-4
AUTOGYRO MTO SPORT
On my AUTOGYRO MTO SPORT, this E-PROPS EXCALIBUR-4 is a really exceptional four-blade propeller.
I had a DUC FLASH-2 before, poor, mediocre, which gave nothing in terms of performance especially in hot weather.
Now well equipped, with a well adjusted pitch (thanks to the technical service of E-PROPS), a balance to the small onions, I am really very satisfied and I promote it everywhere.

DURANDAL-3
RANS AIRCRAFT S-6 ES COYOTE
As soon as I received it, I hurried to assemble my new propeller. The result exceeds, by far, all my expectations ! !
- incredible power at takeoff
- same cruising speed reached with 500 rpm less (165 Km/h at 4500 rpm instead of 5000).
- A remarkable silence, comfort and absence of vibrations.
- I find the spinner very long but I like it a lot….
For your information: the recommendation of the Technical Service was a propeller setting of 21.6º = final setting after testing: 20.7º.
Thanks again – I am a very satisfied customer !

Glorieuse, very satisfactorily constant speed propeller adapted to the Flight Design CTLS.
Modern look and very high-quality infused carbon composite.
Wide cord blade with esthetic gulf wing shape.
Clever, light and fast response electro hydraulic governor.
To compare with E-Props Durandal the gain are: +5km/h + 200ft/mn -1 ltr/h.

ALPI AVIATION PIONEER 200
I did the installation of the propeller without difficulty on my Pioneer P200 100hp.
All technical indications are clear. The pitch adjustment remains the longest operation to obtain the optimal setting (5500 rpm in level which gives me an air speed of 220 km/h).
I particularly appreciated the quality of manufacture of the components.
In summary very satisfied with my e-props in cruising speed 4700 to 4800 rpm, it is an air speed of about 200 km/h...

DURANDAL-3
ALPI AVIATION PIONEER 200
After the first tests made in not optimal weather conditions, I must say that the E-Props, it’ very impressive on my little P200 !
Before I had a wooden 2-blade GT-Propeller, diameter 170 cm, weight 4,8 kg wIth spinner. I have gained 2.2 kg.
Performance are very good. It takes off shorter and I think it could exceed the VNE at full throttle in level (I already had more than 200 km/h at 5200 rpm !)

GLORIEUSE-3
ALPI AVIATION PIONEER 300
Very satisfied with this Glorieuse on my P300.
A reactivity that I did not imagine possible with a variable pitch, probably due to the lightness of this propeller and the regulation system.
We can see that everything has been thoroughly researched by Eprops. To be recommended.

PROPELLERS
Having received my propeller this morning, I wanted to thank you and the whole team for the seriousness of the company.
It's a pleasure to see that despite the road traveled since the creation and the notoriety of the brand, you take the time to treat each customer small or large like this.
From the request for advice, to the respect of the deadline and to the small arrangement for taxes, nothing to say, you are at the top.
The French is a big grouch but you have to know when it's good.
Thank you for everything while waiting for the test which I am sure will be a success.

SERGE PENNEC GAZAILE II
The assembly of the prop went very well, due to the perfect instructions.
I used the proposed angel for the blades.
I had a static engine speed of 5200 rpm wat seemed to be ok for a start.
Then the first take-off… what a power, the plane was ascending at 1300 feet a min…fantastic!!
Then at 2500 f the horizontal flight, the engine had a max speed of 5400 rpm, also very good.
Then I made a flight at the speed a usually take, and the engine speed was 200 rpm lower than with my old propeller…Amazing!
I assume that this result in less fuel consumtion?
I’m glade I made this change.
D.V.R. (2022-09-22)

I had a variable pitch propeller WOODCOMP. I changed for a fixed pitch EPROP. I didn't lose anything in performance on my VL3.
J-M.P. (2022-09-20)

DURANDAL-2
PIPISTREL ALPHA TRAINER
On the Alpha Trainer: shorter take-off, higher climb rate, faster airspeed in level and the green bow used with less power than before => lower fuel consumption. The perfect combo.
G.H. (2022-09-20)

DURANDAL-4
ZLIN SAVAGE big landing gear
Very short take-off with this 4-blade in 190 cm diameter, then after, in cruise, it's so cool: the cruise speed is excellent, at a speed at least 300 rpm lower than with my old propeller, so a reduced consumption. I didn't expect this, it's great.
O.S. (2022-09-18)

EXCALIBUR-4
MAGNI M16 TRAINER
Really impressive this 4 blade propeller on my Magni! A reactivity that I have never experienced before. It must be due to the lightness. It allows me to fly faster. I also take off better. Perfect.

EVEKTOR EUROSTAR
Well, it's simple: by replacing my Duc Flash with your carbon & titanium E-Prop on my Eurostar, I gained 15 km/h in speed, 300 ft/mn in climb and at least 50 m at take-off. No more vibrations and unhealthy noise when starting. In short, very satisfying. I keep this propeller.

DURANDAL-3
APOLLO ULTRALIGHT AIRCRAFT APOLLO FOX
I am writing to you for feedback on the installation of the E-Props DUR-3-165-C4-T propeller on my Apollo Fox ultralight.
First of all: The order, the delivery, the documentation, the installation: Everything was flawless and well set up.
I now have ~ 2 months and over 25 hours of operation with this new propeller.
While I was expecting a performance improvement, I was blown away by the performance gain from the first takeoff! I even had to reduce the propeller pitch by 1 degree to reach the specified 5500 rpm at full throttle.
After these first hours of experience I can see a gain of ~ 30 to 35 km/h, so 20 to 25%, for the same engine revolutions compared to the original propeller of the manufacturer! I can easily reach the Vne of 200 km/h in level at 5500 rpm, never seen with the old propeller.
So I am completely satisfied with this experience and I certainly do not hide it in my exchanges with the other pilots!
H.B. (2022-09-08)

So there, E-Prop, you did a great job. This Constant Speed propeller is a real joy to use. No vibrations, short take-offs even on rough ground, speed 272 km/h, rate of climb 1500 ft/min, in short the best propeller for all flights. I am really very happy.

We had been mounting DUC propellers for years. I was happy with them. Then I tested an EPROP, and now I've changed my mind. Lighter (that spacer is an amazing good idea), more responsive, no vibration, better speeds, and great customer service. The ideal propeller for the Savannah in flying school. Thank you EPROP.

SHARK AERO SHARK
Successful bet for Mack Rutherford (MackSolo): he becomes the youngest pilot to have flown around the world alone!
His plane: a Shark with Rotax 912 engine (100hp) and E-Props ground adjustable pitch propeller Durandal.

A few statistics about this epic journey :
* Total time of circumnavigation: 142 days (= 5 months + 1 day)
* Total distance: 29225 Nm (54124 km)
* Total time in the air: 221 hours
* Average speed = 245 km/h
* Takeoffs/Landings: 68
* Longest flight: 10 hours [Japan-USA]
* Longest flight over water: 10 hours [Japan-USA]
* Highest altitude: 12500 ft [Mexico]
* Continents visited: 4
* Countries visited: 30
* Highest temperature: +48 C°
* Lowest temperature: -12 C°
* Age at time of record: 17 years, 2 months and 2 days [previous record holder: Travis Ludlow: 18 years & 5 months]
* Aircraft: Shark, Engine Rotax 912S, Propeller E-Props Durandal

Mack's sister, Zara, flew around the world on the same plane the year before.
Propellers comparative:
- Zara, with a Woodcomp 2-blade inflight variable pitch propeller, flew 52,080 km in 260 h in 68 flights. Average speed = 200 km/h
- Mack, with an E-Props 3-blade ground adjustable pitch propeller, flew 54,124 km in 221 h in 71 flights. Average speed = 245 km/h
Of course the route was not the same, but everything else was identical: it's the same plane and the same engine.
A great difference in performance! (2022-08-27)

We installed our propeller on A32 yesterday.
Wau! What a difference! Easy to install, smoother, quieter, super take-off, 5 kts more cruise and 1500 ft/m.
Much better on all parameters.
But we had to adjust trim because we removed 1,5-2 kg from the nose.

BLACKWING SWEDEN BLACKWING
Blackwing pulverizes the 400 km/h !
The little jewel, all carbon, after a first appearance in 2015, made a remarkable return to Blois (French air show) last year, in a top level configuration, including retractable landing gear, Rotax 912S 100 hp injection engine, E-Props inflight variable pitch propeller Glorieuse, Garmin G3X full glass cockpit. It was the Blackwing 600RG model, intended for the French market with a maximum take-off weight (MTOW) of 525 kg.
At the AERO 22 show, the European version 635RG was presented, with an MTOW increased to 600 kg and especially a Rotax 915iS. With this engine block providing 40% more power, the Blackwing reached the incredible speed of 413 km/h ! Without any chauvinism, let’s bet that if the machine (Swedish) and the engine (Austrian) are for a lot, the propeller (French) is not for nothing. The Glorieuse, which was presented for the first time at AERO, also breaks a record in terms of weight: 4 kg for the complete system, including the propeller but also the spinner , the pitch control and the control box !

Instead of my warp propeller I have mounted an eprops excalibur with 4 blades. I really like its smoothness, no vibrations and the performance especially at takeoff from the lake. The titanium protects the leading edge of the blades which is an advantage on the water. It is a very good choice that I recommend.

PIPISTREL TAURUS
PIPISTREL APIS
This is the 3rd Pipistrel Taurus that I have equipped and I helped 2 pilots to make the documents for the French Civil Aviation Administration (DGAC).
The gain in safety is important because the propeller stops immediately, contrary to the wooden propeller which imposes to slow down its speed and to put itself in danger of stalling.
No more need to weld the jacks of the exhaust pipe which cools down more slowly.
The Rotax 505 gives all its power. At Serres airfield (LFTM), if the wind is south and therefore backwards, with the wooden propeller, I asked for towing.
Certainly 1 gain in glide if the engine blocks, pylon out.
Gain in rate of climb.
1 kg of gained.

Anecdote by Anne Lavrand, president of Hélices E-Props :
The circle is complete. I started my career in the 90s as a pilot and sales manager at AVIASUD ENGINEERING in Fréjus, on the Sirocco and the Mistral, then later on the Albatros. At that time, the Mistral was considered as a top-of-the-range ultralight, light, very thin and pleasant to fly. I keep an unforgettable memory of the flights made all over France aboard this aircraft.
AVIASUD was working with the company ARPLAST for the propellers; I took part in many test campaigns of new models of propellers on these aircraft.
I didn't know that one day my own company would manufacture propellers that would be mounted on Mistral and Albatros! Funny. (2018-05-18)

ATEC FAETA 321
Hi E-Props Team,

I wanted to make a small report of my tests of the E-Props Durandal 100, V12, 170 CM on my ATEC FAETA.

Here is a small comparison between my old FITI 2 Blade ground adjustable propeller and the new E-Props 3 Blade Durandal ground adjustable:
First to start, the E-Props propeller setup as instructed was perfect: 28 degree pitch give 5200 Rotax RPM at full throttle stop, 5500 RPM at full throttle maximum speed in horizontal flight.
The Fiti was set up similarly with a maximum speed in horizontal flight of 5600 RPM.
Takeoff with one person on board: I estimate 70 to 80 m of taxiing with the E-Props vs. 100 to 110 m with the Fiti.
Takeoff with two people on board: I estimate 100 m of taxiing with the E-Props vs. 130 to 140 m with the Fiti.
Significantly less engine torque at takeoff. The Fiti was pulling so much to the left that I had trouble keeping the machine in line with the runway: this torque is totally manageable with the E-Props propeller, a slight correction to the right is enough.

When climbing alone I gained at least 1 m/s with the E-Props, especially in fast climb: at 160 km/h, I got a climb rate of 6 m/s with the E-Props, at 120 km/h 7.5 m/s!
Same for the climb with two people on board: a gain of about 1 m/s compared to the Fiti.
In cruise the performance gain is really amazing:
With the same intake pressure and the same engine speed, we gain almost 30 km/h with the E-Props propeller!
Speeds are ground speeds measured as an average in two directions and at 4000 feet altitude:

FITI:
4500 RPM - 160 km/h
4700 RPM - 170 km/h
5000 RPM - 190 km/h
5200 RPM - 205 km/h
5600 RPM - 235 km/h

E-Props:
4500 RPM - 190 km/h
4700 RPM - 200 km/h
4900 RPM - 210 km/h
5000 RPM - 215 km/h
5200 RPM - 225 km/h
5500 RPM - 236 km/h

So what is surprising is that the maximum speed does not change much, but I attribute this to the aerodynamics of the Faeta, which flies too much in a nose-down attitude at high speeds above 230 km/h.
Finally, the engine's comfort with the E-Props propeller is much better, with no vibration on the whole rpm range from 1800 to 5500 RPM.
Another interesting aspect: the cooling of the cylinders and the oil in continuous rise at 120 km/h was limited with the FITI propeller. With the E-Props the temperatures are 5 to 10 degrees lower.

I can confirm that there is no doubt that the performance of the three-blade E-Props propeller is superior to the performance of the two-blade Fiti propeller, which was designed specifically for the ATEC Faeta. To summarize E-Props vs. Fiti:

Shorter takeoff
Lower engine torque
Faster climb
Much higher speeds
Reduced vibrations
Better engine cooling

With kind regards,
Martin G. - France

Contact you to share the tests of my e-props in Tecnam P92 ECHO S with Rotax 912 ULS 100CV engine.-

First Test:
26 ° C, QNH 1019, 2500 ft MSL. Pilot plus passenger = 190 Kg.
Green = 26.45º / Red = 26.45º / Blue = 26.45º
Maximum power 5400 rpm 28.5 inHg.

Second Test:
18ºC, QNH1014, 2500 ft MSL
Green = 26º / Red = 26º / Blue = 26º
Maximum power 5400 rpm 28.5 inHg

Third Test:
18ºC, QNH 1014, 2500ft MSL
Green = 25.4º / Red = 25.4º / Blue = 25.4º
Maximum Power 5500 rpm 28,5 inHg

The E-props propeller weighed 2,650 Kg, the Tecnam GT propeller that I have removed weighs 6,950 Kg, there is an important difference of 6,300 Kg. I have noticed the first thing when starting the engine, it starts much more easily and stops the motor is not jerky.

All three flight tests have been successful, mostly because of the IAS speed gain, but my preference is to sacrifice speed for climbing ability. From the first test to the third I have been gaining climbing ability. Since my plane is a school plane, I would like to know if I can still gain more climbing capacity, that is, do a new test going from the current 25.4º to 24.8º and get 5400rpm at maximum power.
Thanks.

EVEKTOR SPORTSTAR
The performance of the E-props propeller on my Sporstar has been outstanding. It has performed better than my expectations. My full throttle speed at 5500rpm when straight and level is now 110kts and my climb performance is unaffected and remains around 1100ft/min.
I like to fly with 5200rpm and at that RPM, the plane does around 100kts. Previously, my Woodcomp Kompact propeller would only provide me under 90kts at 5200rpm.
I am also still using the 2.5kg temporary ballast, as I have not yet had a chance to confirm my weight and balance limits. I expect that I will likely need to reduce the maximum luggage that I can take from 25kgs to 20kg or less when removing the ballast.
One comment with regards to the pitch measurement tool. I broke it almost immediately when I tapped with the rubber mallet on the propeller to adjust the pitch, the pitch tool fell off the propeller and shattered into pieces on the ground. You should make the 3D model available for 3D printing at home so that anyone can re-print it if they break it (the file of this part is available for free on the store. You may also consider making it from PLA instead of ABS, it will likely be much less brittle and break less easily when dropped.
Thanks for all your great work and an outstanding product overall.

We have just made the tests of your propeller which was already installed on a Eurostar... without the corresponding identification card. These tests with a Provisional Card, will make it possible to validate this modification known as major near the DSAC-SO (French Administration).
The performances obtained at takeoff are very surprising in superiority compared to those of the Eurostar User Manual. We have made videos and the take-off distances have been well identified to within 10 meters. The ground run corrected for wind gives us 85 meters to compare to 150 meters and the passage of 15 meters in 200 meters to compare to 280 meters of the user manual.
The grass is very short on the middle of the dry, hard track used, but I think I can improve the 15 meter passing distance with a more optimized V2.

You can read anything and everything on the Internet. So I did my own price comparison between E-Props and Duc.
Because you have to compare comparable things.
So I took the prices of a 3-blade Swirl-3 and a 3-blade Durandal-3, both for Rotax 100 hp engines, both adjustable on the ground, both on 101.6 hubs, both from the manufacturers websites.
Both with a 250 diameter spinner and a 50 mm spacer: an average of what is proposed by the 2 manufacturers. The prices are without taxes.
Without accessories.
Duc = 2116€.
E-Props = 1830€.
So the Duc is 286€ more expensive than the E-Props.
Here are the real numbers.

Take off to Level 100 in 8 minutes at 130km/h (only on board and 50L of fuel).
The Titanium version compared to the v12 gives a +-50m shorter takeoff on my machine because I'm at 5480 rpm at brake release and at 2500' full throttle 5530 rpm.
There we only see a very small value of +-50 rpm against +-100 rpm variation with the v12.

AUTOGYRO MTO SPORT
I was curious how much thrust is available on the MTO.
So we took a scale and measured the thrust: both engines Rotax 914, both props optimized to the engine (100% throttle roughly 5500rpm, 115% 5800 , with variations due to wind, rpm-meter, etc.).
One MTO with a HTC propeller, one MTO with E-Props Excalibur 6.
Here the results:
HTC:
idle throttle:25 kg
100% throttle: 170kg
115% throttle: 203kg
Excalibur-6 :
idle throttle:30 kg
100% throttle: 205kg
115% throttle: 235kg
The method was not precise in absolute numbers but shows that 15% gain in thrust is reasonable.

I installed your propeller on my delta trike with Rotax 582 red.2.62 engine.
The assembly was very simple.
In flight it is wonderful: very quiet in flight and on the ground.
An exceptional boost.
The propeller load is perfect on the engine 582 with reduc 2.62 .
At take off 6600-6800 rpm
5000rpm level flight at 300 meters altitude at 85 Km / h speed (IAS).
Very responsive to the throttle.
Incredibly low propeller weight.
During the weekend I did 2 hours of flight and I am very satisfied with the E-props three blade propeller.
I finally found my favorite propeller thanks to you.
Congratulations to all Team the E-Props product.
I will certainly recommend it to my fellow Delta trike Pilots.

I thank you again for your welcome and the visit of your facility in Vaumeilh.
I mounted the propeller on my 100 hp Tetras on Sunday and did the tests this morning. You can imagine that the performances are incredible, + 500 Ft in rise, and the speed in level is increased of more than 20 %, without speaking about the takeoff which is surprising, I did not believe my badin, so much the needle was panicking, I thought that it was the vibrations of the rolling which disturbed it, but by taking the slope of rise to 110 km / h I quickly realized that there was nothing any more to be believed but only to observe.
Another pilot arrived who has a 100 HP Trial in Les Crots, he went to see a friend who has the same Trial as him but with an 80 HP engine, who has just mounted an E Props and they have the same performance, the 80 HP with an E Props and the 100 HP with a 2-blade...

Bit lumpy air so I don’t have accurate figures yet. But looking like 8 Knots increase cruise. Climbing well but feels very very different.
I have been doing a few circuits. Climb rate is best at 70knots 1100fpm. Previously best at 50knots 1100fpm. 40knot climb is much less at around 600 fpm
Pretty happy with it. Much easier to start. More responsive to throttle. Taken weights off the back for balance. Feels very different

I made several tests in flight on my EUROSTAR and it is satisfactory.
I gained approximately 8 kts in cruising speed and at 70 kts in climb I am at 1180 ft/min.
The most impressive is the absence of vibration.
An unforeseen consequence:
By temperature negative I had difficulty to start because the conjunction of the cold oil, the cold engine and the pitch of the propeller caused me many problems of starting.
Indeed the rotax not having a magneto it is the number of revolutions of the starter which conditions the starting.
And oh surprise without preheating the engine I started every time.
So I am very happy with the Eprop.

I have full confidence in your propeller. It has shown that it is performing about the same as IVO Prop flight adjustable but it is much stronger. I have done some testing on the vibrations with DynaVibe and E-prop is much smoother than IVO props (which is the most used prop here) in all cases. I can also say that IVO prop needs much more maintenance since we are using runways with small rocks which cause dents in the blades.

Hello team. Here are the measurements I made comparing my old Woodcomp with my new E-Props with Titanium protection. Both propellers set with the same pitch.
Here are my measurements:
- propeller weight = gain of 2,2 kg because Woodcomp 4,2 kg and E-Props 2 kg.
- take-off distance: the gain is 25 m at take-off with the E-Props
- climb rate: gain of 220 ft/min with E-Props
- cruising speed: gain between 15 and 20 km/h depending on the speed
- fuel savings: about 7 to 8%.
- with the E-Props, vibrations have been significantly reduced.
- the noise, low for both propellers, is also less noticeable with E-Props (measured by overflights at 300 ft)
I am very satisfied and I will recommend your propeller to all my friends.

Hi, I have been flying for about 7 months with my 4 blade e-prop fitted to a SeaRey. I honestly could not be happier. Performance improved dramatically over the IVO prop that I had on before. As an added bonus the vibration that I used to think was normal has completely disappeared. I gained about 7knots speed (a big deal in a SeaRey) and it climbs 300 ft/ min better.
Worth every extra cent that they cost in my opinion. They look a bit flimsy - but it's handled water operations without a mark. They are certainly a lot tougher than they look.

Very fast takeoff, at 110km/h in climb speed the climb rate is significantly improved, in level at 5000 rpm it is at 140 km/h which is an improvement of 20 km/h compared to the previous propeller (so at the same speed a lower fuel consumption).
No vibration 'the Guepy loves his eprops propeller' and reacts with great finesse, he just wants to fly.....
To sum up, I confirm an improvement of 15 to 20% in all the flight domains. We liked this aircraft very much and now it is even finer and more performant. The noise is muffled and very pleasant.

EXCALIBUR-4
MAGNI M16 TRAINER
Yesterday, I finished the tests of the 5-blade propeller with Titanium leading edge protection on my Magni M16 gyrocopter with Rotax 914 engine.
Compared to the 4-blade (with Titanium leading edge protection), I did not notice any really convincing difference in terms of performance.
The 5-blade is more pleasant in flight with a 'smoother' rotation and less vibrations.
I had asked some colleagues to be posted on the airfield and in the lap of the runway in order to have a return on the noise.
Even if the perceptions differ from one person to another, it turns out that the 4 blades are perceived as less noisy in flight during laps. The noise is quieter and seems to spread less as the machine moves away.
Thank you for taking into account my order for a new 4 blades with Titanium leading edge protection.

EVEKTOR SPORTSTAR
Impressive this E-props Durandal-3 propeller with its Titanium protection.
Seeing the blades so thin and light, we didn't think it could give such traction on the Sportstar with its Rotax 100hp. Yet, it performs its function from takeoff to top speed.
Here is what we measured, not set at 26°:
- Takeoff in 120 m, a litte less
- Cruising speed 95 kts at 75% power
- Max speed : 120 kts
- Consumes about 5% less than the old propeller, which was a 3-blade ground adjustable pitch Woodcomp model Klassic 170, measured over 250 flight hours.
- Significantly less vibration in all speed ranges
- Weight gain: 3 kg
A success.

Unfortunately, I am well aware of the galvanic corrosion problems generated by the contact between metal parts and carbon-epoxy, having problems with one of your competitors. Therefore I did not want to test your propellers. But I had the opportunity to see one of them up close, and I could see that you have solved this problem: no metal parts in contact with carbon-epoxy. Your propellers are remarkably designed and manufactured and, after testing, are remarkably efficient in terms of performance. I predict a very great success and I warmly congratulate you.

Here is the Avidflyer (MARK-IV, STOL, wingspan 9.20m, wing area 11m2) equipped with your Durandal Propeller diameter 1.80 m, with a Rotax 912 ULS2 100 HP.
First propeller pitch recommended by you, 21.3°, pitch actually done on the 3 blades 20.6/20.6/20.7.
Test conditions this Saturday 17/10/2020: null wind, 10° ext, measured with a needle badin and a vario with needle; the GPS not yet used for this test often confirms the values in null wind.
Takeoff on grassy, bumpy ground, slightly rising slope, between white lines 250 meters, +- 100 meters for takeoff.
Result :
- takeoff with full engine load at 5350 rpm, full load landing at 5500 rpm.
- Climbing speed: full engine load after take-off landing, 10.5 m/s at 100 km/h (404 kgs, aircraft, 1 pilot, 30 liters of fuel) at 5300 rpm.
- Climbing speed : full engine load after take-off, 6.8 m/s at 110 km/h (at the maximum load of 482 kgs) at 5300 t/m.
- Ideal cruise 150 km/h at 4300 r/m.
- The maximum speed reaches 205 km/h at 5500 rpm (VNE 217 km/h).
This Avid is a real STOL ULM!
Your propeller, extraordinary traction, no vibration, no noise!
Super satisfied, I recommend it!

On my Gyro AIR COMMAND 912S, I made some tests last Saturday afternoon, at the recommended pitch... I would have only one word: REMARKABLE!
I have the impression to have 'put' horses in addition. And in fact, it doesn't matter the horses or ponies under the hood...the most important thing is the quality of the propeller set up for the good operation of the engine. And there you are very good, THANK YOU!
I continue the tests, and will go from 20.7 degrees to 21.3, in order to get closer to 5800 rpm at takeoff power max.
Surprisingly, while I hadn't informed my wife about the propeller change, she asked me why, after flight, the gyro didn't make the same noise as usual...it makes less noise...she told me. Thank you very much for that too!

Hello team,
I replaced my warpdrive propeller on my Sky arrow 80hp with your 3-blade model and I must say I'm very happy. I cracked because I wanted the titanium protection. It's really very nice.
Performance: the thrust is there. I take off shorter (about 20 m less), I fly faster (160 km/h now, whereas I had only 145 km/h before), the engine consumes less (calculations made over 20 hours of flight: -6.5% fuel). Vibration: it's a real pleasure to fly with the eprop, because it doesn't vibrate at all and is very reactive.
Thank you for your help in my choice. You are the best!

5400 @ 125kts (This was only held for a short period but we believe the speed could have continued to increase at this throttle setting)
These results vastly exceed anything seen with the previous Neuform. At times, with 2-up, we were battling to hit 105kts in good conditions.
Some observations:
There is a noticeable lag when throttle is applied rapidly – it’s only momentary, but noticeable. We think this may be a characteristic of the high aspect ratio producing momentary cavitation. It’s not problematic, especially as all of us use gradual throttle increases.
Given the reduced swept area of the props, it may be that the breaking effect on final is reduced – again, not a problem but requiring a bit of relearning.
VERY pleased with the results. The E-Props system definitely exceeds our expectations.

ICP AVIAZIONE SAVANNAH S
There is a little more traction with the Titanium propeller than with the other Durandal 100 I had. I'm glad I changed. We still need to make some more adjustments to optimize it. For the moment, the engine reachs 5600 rpm at 205 km/h, and at 5100 rpm with 26.5 of map it cruises at 180 Km/h. For a Savannah S, I think that's enough!

ICP AVIAZIONE SAVANNAH HYDRO
It pulls, the DURANDAL 185 on my Savannah hydro. Nothing to do with the other propellers on the market. You can see that it was designed for that.
The titanium blade protection completes the e-props picture. A great future for this French company.

AEROPRAKT A22 L2
Have installed your prop and are very impressed with performance.
On my Foxbat A22LS Rotax 912 uls2, in comparison with my warpdrive propeller :
I set pitch originally at 24.6 degrees which gave me 5720 WOT on ground.
Set pitch to 25.6 degrees which gave me 5620 WOT on ground.
Test flew did not get take off distance but felt improved.
Climbed out 60kts no flap 1200fpm full fuel 1 pob.
WOT straight and level 5430 107-110kts TAS.
Best cruise 5250 TAS 100kts. 100ft density alt 12degrees c. 3500ft indicated.
For my set up I gained a true 8 kts more at cruise.. with no vibrations totally smooth.
Starts nicer and shuts off with out the clunk.
Awesome piece of gear.

THE COMPANY
Thin blades that are undeniably more efficient on cruise than the direct competition (less induced drag), no wonder, but the efficiency with the right pitch and diameter of these same blades surpasses all other brands of propellers. This is called a good shot in the anthill of good dad's propeller ideas.

L.T. (2020-07-05)

DURANDAL-3
AEROSPOOL WT9 DYNAMIC
We increased the pitch to 30.2° because we measured 29° on our WT9.
This gives the first quick tests, because turbulent atmosphere, 5520 rpm on brakes, full throttle at 5460 with 270km/h and at 5000 rpm 255-260 km/h. And I think I have shortened the take-off distance.
So very good... in that respect.
What's not so good is that your adjustment tool turns off after a few minutes. So you have to recalibrate it, which makes the procedure more random. So we used another tool that doesn't have this defect. Is there a setting to prevent that?

TECNAM P92
I installed the Durandal propeller on our Tecnam P92, we have now better performance, in particular:
- the shortened takeoff run;
- increased rate of climb;
- higher cruising speed;
- less noise;
- reduced engine idle;
- turning the delicate Rotax 912 100HP off and on;
- the propeller disc in flight is completely invisible. This compared to the previous Italian two-bladed GT two-bladed propeller.
Excellent product, really!
For a take-off of 5500 rpm, we have set the pitch to 26.70 degrees instead of the recommended 25.50 degrees.

DURANDAL-3
AEROPRO EUROFOX
E-Props propeller ordered for a Eurofox 3K.
the Woodcomp is really too basic and no constant speed effect so not very good in terms of efficiency.
The main reason for this choice is the lightness of the propeller and cone assembly.
The Woodcomp carbon weighs 5.2 kg and with the extension of the aluminium hub with the cone, one should not be far from 6 kg.
We are at the upper limit of the moment of inertia as predicted by ROTAX.
The E-Props weighs 2.5 kg and the complete cone 510 grams, so the difference is almost 3 kg. In terms of the moment of inertia it is day and night.
I finally found the optimum setting for my E-Props, almost identical to epsilon near the recommended setting, so 22.4° for 22° recommended.
I get 5350 rpm full throttle dry with 10°C temperature and 5500 rpm full throttle in level.
I climb to 5250 rpm at 90/100 km/h which is very good and perfectly in the Rotax layout.
The performance is there, it climbs much better, it goes faster and it doesn't vibrate anymore.

The new e-prop propeller I've fitted is fabulous! Takeoff as short as with the FITI, it goes up to the trees, cruising speed: increased by at least 20 km/h! I couldn't believe my eyes: I went from 190 to 210 km/h at 5000 rpm. You can physically feel that the propeller is super light: no vibrations, reacts very quickly to rpm changes, and no "clank" at engine stop. A killer, absolutely to be recommended!
M.R. (2020-02-20)

THE COMPANY
As I've said before, I think the E-prop adventure is fantastic because rather than the easy way out, you've chosen the path of merit.
By not hesitating to challenge some established rules and some references, even if it meant being criticized and robbed of green wood, you have just achieved what most people thought was impossible.
I therefore salute your open-mindedness, exacting standards, independence, creativity and high technicality: qualities that are sorely lacking today in many organizations that have succumbed to the sirens of superficiality.

Bravo for your Service Bulletins which are very detailed and very didactic. Thank you for your safety first approach.

The installation of the Excalibur 6 propeller on my ELA Eclipse gyrocopter does not conform to your recommendations. The bolts are quality 8.8 instead of 10.9.

In the end I like it and I keep it.

TBO
A TBO of 2000 hours is an essential advantage for a flying school, compared to competing propellers. Then when you send the propeller back to eprops for overhaul after 2000 hours, it only takes a few days! The TOP.

TECNAM P96
I am very satisfied with my propeller and agree to share my experience to help other customers choose e-prop.
I had a two-blade wooden propeller GT diameter 165 cm ref GT-2/173/155 with a big enough pitch, correct for cruising speed (192 km/h) but which required a very long run (180 m) and the climb rate was 820 ft/min.
With the Durandal e-prop with three blades diameter 170 cm, ultra-light, I take off very short (105 m!) and the cruising speed is even higher: 206 km/h at 75%. Climb rate = 1150 ft/min.
Then you can take an e-prop without hesitation. Moreover it is very beautiful with the carbon and the Titanium protection.

Thanks Matthieu for the express editing in Niamey and E-props for this super propeller... day and night with the DUC!! Savannah Bingo ULM les Noyers.
I didn't think that there could be so much difference in all the flight compartments, at takeoff it pulls a lot but much stronger, me who flies a lot on short bush runways it's very reassuring, in flight a rate of climb for my part 2 times higher, a faster flight at the same engine rpm, a decrease of vibrations (really feel it), and a better cooled engine.
I've seen this in my flying environment, in Africa with outside temperatures over 40°.

On our previous propeller - Duc - we encountered serious electrolysis problems on the aluminium base, which forced us to replace them quickly on our Corvus.

So we're winners. Bravo Eprop!

I've been flying Savannah S for more than 2 years, performance/consumption with E props propeller and 800 bush wheels, pilot alone :
- 120 km/h : 8l/h 4000 rpm
- 130 km/h: 9l/h 4200 rpm
- 140 km/h: 11.5 l/h 4400 rpm
- 150 km/h: 13.5 l/h 4600 rpm
- 160 km/h : 16,5l/h 4800rpm
- 170 km/h: 19l/h 5100 rpm
- Full throttle 175 km/h: 20 l/h 5500 rpm
I fly mainly at 120km/h to enjoy the landscape, my pleasure is measured in flight time and not in distance, I limit fuel costs.
For me the "reasonable" maximum cruising speed is 150km/h, to enjoy a nice autonomy.

EXCALIBUR-4
DTA VOYAGER
In 2013, I also did a propeller comparison on my 80hp delta trike. Between Arplast, Duc and E-Props.
On my DTA Voyageur I had an original Arplast.
Being neighbour of Duc, they had the good idea to lend me a Duc Flash for tests.
And since you can try an E-Props propeller for 6 months and return it if it doesn't suit you, I was able to try the Excalibur-4.
I set the pitches so as to have a maximum speed of 5400 rpm in static.
If the Arplast takes about 100 t more with speed, the Duc loses a hundred and the Excalibur more than 200.
Only the Excalibur allowed me to exceed the VNE in level flight.
That's the one I kept.
Since then I've opted for the Excalibur-6 which is quieter and I gain a few meters at takeoff.

THE COMPANY
I appreciated the visit of your workshops but I am not completely happy. I would have liked to see in detail how you make composite parts, but the person who showed me the workshops told me it was confidential. That's a shame.

A little feedback with my three-blade E-prop.
Good commercial contact: no hitch, targeted technical advice, offer comes very fast.
Well-packed package. Fast shipping.
Everything is included in the package: screws, covers, adjustment tool. There are some gifts from the brand; it is appreciated.
It is necessary to be rigorous for the assembly and the adjustment. A first pitch is advised by the technical service. With a little precision you can do it.
Checking the tightness according to the instructions. The Manual is a little long to read but interesting.
Then, tests on my SKYPER GT9. I'm not a specialist, but I find the best at takeoff and climb. Above all, I don't feel any vibrations anymore and the cruising speed has increased from 10 km/h to 4800 rpm.
In conclusion, a very good experience with E-prop.

3I SKY ARROW
Here is a summary of my experience of working with e-props :
Aircraft - Sky Arrow with Rotax 912UL - 80HP - 16 hours flying time with e-props.
1) Initial enquiry dealt with very efficiently and with high quality information
2) Order shipped on time
3) Good cooperation with the UK LAA to gain authorisation to use the prop in the UK on an LAA aircraft
4) Prop fitting instructions very clear and the digital protractor works very well
5) Just three flights required to optimise the prop pitch
6) Very low vibration level - almost none
7) Very little difference in climb rate or take off roll compared to previous ARPLAST in flight variable pitch prop but 5.5Kg lighter
8) Very resistant to stone damage - the leading edge protector works very well
9) Two technical queries answered very quickly
10) Minor damage to leading edge tape (no damage to prop) - replacement tape sent within 48 hours
In every respect I would recommend anybody considering a new prop to look at E-props. From my experience the company produces a very good prop and is very good at support and really cares about it's customers.
I look forward to seeing how well the in flight variable pitch prop performs.
Many thanks for all your assistance.

FLIGHT DESIGN CTLS
I have installed my new propeller (Durandal 3 blade) that arrived in very good condition from France.
It was much easier to install and setup than what I thought it would be. The protractor and hook attachment that was provided worked flawlessly.
The assembly manual was easy to read and clear in the instructions as what to do.
I did the ground tests at the recommended pitch and it was exactly the good one.
I have flown approximately 25 hours with the e-PROP and I am still amazed at the difference it has made to my CTLS.
I have gained at least another 300 ft per minute climb and a good extra 8 knots in speed, compared with my old Neuform propeller. But this is not the major advantage – I cannot believe how smooth and quite this prop is. There is no vibration to speak of and I can speak to a passenger without headsets on.
Please send my compliments to the technical team who work so hard in the background to design and manufacture a magnificent product.

ELA ELA10 ECLIPSE
I've been using this propeller for 3 years and 450 hours, on 2 different Eclipse without any problem and I know a lot of pilots who are totally satisfied with it.
I have no interest in E-Props, I share my experience.
I think that this propeller should be installed by a professional and have read the installation manual which like any manual must be respected.
The adjustment and tightening were done with the adjustment tool and the studs provided by E-Props and a torque wrench respecting the tightening torque of E-Props.
This year I have made several raids for a total of nearly 8,000 km at a speed of 150 kms / h without vibration and without having to tighten the propeller during my tightening checks.
With this 6-blade E-Props propeller, my Eclipse made flights of more than 500 kms between 150 and 160 kms on average with, a regular maintenance, Mécarun C 99 in gasoline and an Averso rotor 8,70 m well adjusted and by remaining on average 25 liters of reserve in the tank, the propeller has thus its share in these performances.
This gyrocopter is to my knowledge equipped as it is, the fastest in the world over 500 to 600 kms without refueling.
Here is my experience.

I had been warned about your propellers, but the speech of your opponents was so confused that I was suspicious. Whoever wants to drown his dog accuses him of rabies.
Well, it's a good thing, because I'm conquered. Kick your ass on takeoff, soar, step speed higher than before. With the added bonus of outstanding commercial support.
In short: you should never listen to other people's opinions. Especially when these others have financial interests in the competitors.

HUMBERT AVIATION TETRAS
Comparative tests on ULM Tetras equipped with a 2-blade DUC Windspoon propeller then equipped with a 3-blade E-Props Durandal-3 diameter 175 propeller.
Conditions => Total take-off weight : 420 Kg / T°: about 2°C / Pressure at QNH 500 m : 1023 mb / Wind on the ground about 30 Km/h at take-off / Wind on zone : 10 Km/h from north between 3000 and 6000 ft.
The significant results are voluntarily limited between 3000 ft and 5500 ft for powers corresponding to those usually used, i.e.: 4400 to 4800 RPM.
* Rate of climb between 3000 and 5500 ft at 4400 RPM => + 200 ft at 3000 ft / + 100 ft at 4000 ft / + 50 ft at 5000 ft
* Rate of climb between 3000 and 5500 ft at 4600 rpm => + 100 ft at 3000, 4000 and 5000 ft
* Rate of climb between 3000 and 5500 ft at 4800 rpm => + 50 ft at 3000 and 4000 ft / identical at 5000 ft
Indicated speeds between 3000 and 5000 ft => between 10 and 20 Km/h at all powers and all altitudes
Conclusions:
Gain between 100 and 150 ft in rate of climb especially between 3 and 4000 ft, after 5000 ft the rates of climb are about the same with both propellers.
On the other hand the indicated speeds are very clearly higher with the E-Props propeller between 10 and 15 Km/h and sometimes even approaching 20 Km/h.
We can affirm that on the Tetras the E-Props propeller is globally a little bit better in climb and above all clearly superior in cruise.

Meeting GALDEZ 2019 : Eric Grare on his ULM G1 with E-Props propeller big winner.
The GALDEZ competition, inspired by the prestigious VALDEZ, took place on 15 and 16 February 2019 in Gap-Tallard, bringing together 16 ULMs (3 gyros and 13 multi-axis). Objective: to measure which took off and landed as short as possible.
For the multi-axes, it was almost a single type competition: ultralights of the same mass equipped with the same engine. The only differences were the pilots and the propellers.
Eric Grare (well-known motorcycle competitor) put everyone in agreement with his G1 Rotax 912S and his propeller E-Props Durandal: takeoff in 25 m + landing in 17 m = total 42 m!
The next best totalled 74 m, i.e. 32 m far behind. Jean-Louis Schlesser, aboard his Storch 912S with Duc Swirl-3 propeller: take-off in 44 m and landing in 30 m.
Magnificent victory for Eric, an outstanding pilot who chose his equipment well... (2019-03-05)

AEROSERVICES GUEPARD SUPER GUEPARD
Here is my experience of using an E-Props propeller. Attention, I am a standard pilot, zen, non polemist, non scientific, non handyman, and have no other experience than my own machine, except 20h on Skyranger.
The aircraft : Super Guepard SG10A (aluminium wing 10 m2), Rotax 912 100 hp, LAD-Aéro injection, 900 h.
The propeller: E-Props Durandal 3-blade 170 cm used on 170 h.
After being shown at E-Props how to adjust my propeller on the ground, I manage to do it myself!
The 'factory' setting, set to have 5500 rpm at full throttle, allowed, not to make the plane take off, but to pull it off the ground !!! On the other hand, in cruising level I found the rpm too high, with the noise that followed.
After a few tests, I currently have a little too extreme stalling (28,6°): barely 5000 rpm full throttle, but then in cruise: what a speed, what a stretch, what an auditory comfort! 105 kts for 4300 rpm, about 12 l/h. Nevertheless, the takeoff, without being a 'tear-off', remains quite short. On the other hand, and it is obvious, the engine is struggling a little at the climb, it can't take its turns, it is not good, and it is even more sensitive beyond 10.000 ft.
After this test, I'm going to go back to a more reasonable setting of 28° to start with. To be continued...
Note: these impressive shimming figures are due to the strongly concave profile of the E-Props propellers at the distance from the hub (40 cm) where the measurement is taken, so they can't be compared to the shimming of other propellers.
My Super Guepard was previously equipped with a 3-blade Swirl Duke propeller with a 175 cm diameter.
I find that my new propeller E-Props Durandal diam 170 cm is more versatile. It takes its turns better at the acceleration of the takeoff, and without ever cavitating. In cruise, it seems to me that its profile is more efficient and therefore generates less drag. In downhill cruising (300 ft/min) it is even more marked, the acceleration is more important. In gliding flight, the glide ratio is slightly improved.
These are my impressions. Obviously, I am not a test pilot. Rigorously, I would have had to take into account the blade settings, but I don't think I'm wrong (besides, we couldn't compare the settings because the profiles of the blades are completely different).
Two other points:
- the setting is easier to do by yourself.
- the weight gain is between 1 and 2 kg, it's good for the engine, and I didn't feel it on the trim level

AVIASUD ENGINEERING MISTRAL
Anecdote by Anne Lavrand, president of Hélices E-Props :
The circle is complete. I started my career in the 90s as a pilot and sales manager at AVIASUD ENGINEERING in Fréjus, on the Sirocco and the Mistral, then later on the Albatros. At that time, the Mistral was considered as a top-of-the-range ultralight, light, very thin and pleasant to fly. I keep an unforgettable memory of the flights made all over France aboard this aircraft.
AVIASUD was working with the company ARPLAST for the propellers; I took part in many test campaigns of new models of propellers on these aircraft.
I didn't know that one day my own company would manufacture propellers that would be mounted on Mistral and Albatros! Funny. (2018-05-18)

DURANDAL-3
BRM CITIUS
A first feedback with a propeller set according to EProp data (my Duc was a priori set according to DUC data: 23° (from memory) with maximum speed at go-around of about 5,200 rpm):
- a much higher take-off power with a shorter taxi and a higher rate of climb (+200 ft/mn)
- to have the same cruising speed you need more turns than with my Duc but a priori the AP must be a little lower (consumption a little lower)
- the EProp argument with the same rotation speed in climb and cruise (full throttle) is checked
- less vibration
- a much softer stop for the gearbox.
In fixed point I have 5,500 rpm then 5,400 in initial full throttle climb and I will, in the next few days, slightly increase my step to go from 24.3 to 25 / 25.3
These data are from about 5 hours of flight with this new propeller.
EProp gives -100 rpm for + 0.6° of pitch. To be refined with additional tests.

Hi Anne, I just received formal approval from Aeroprakt for the installation of the e-prop on the A32 in compliance with ASTM LSA standards. The approval is attached below.
We were able to install and test the new E Prop. The results were fantastic for all engineering parameters!
I tried to do collect test data to provide a comparison before and after with results attached. Please note that vibration, impulse forces and noise data were simply recorded with apps on the panel mounted iPad. Thus would suggest the data provides relative rather than aboslute data for the two props.
We tried to ensure that the flight conditions (gross weight, temperature, winds, etc) were also similar for the test flights. The results were very impressive.
Anne, the only issue that has come up is that we have observed some fading on what is assumed to be the protective clear coat finish on the blades and spinner. [it was this has been solved with a light polish]

I own a FK14, and currently I use a Idrovario, variable pitch propeller in flight (7,8 kg).
I have tested an e-Prop with 3 blades of 170 cm and I must say that at equal parameters (RPM/Map) I have all the same performance.
The Idrovario has the advantage of the variable pitch in flight, the E-Prop the advantage of the weight.

Autogyro instructor pilot, I just bought a 6-blade excalibur propeller.
First of all, congratulations to the whole E-props team who is of an irreproachable availability and professionalism.
Concerning the propeller mounted on a Rotax 100 hp ULS :
At takeoff, a power equal or even superior to a 914 turbo!
In climb, more than 1000 ft/min and it keeps pushing!
In cruise, gain of 600 rpm for the same speed performance.
In short, a real pleasure which, in addition, considerably reduces fuel consumption.
Solo performance, 28° outside temperature, Alti terrain 266 ft.

I am interested to find out how your proppeller survives winter. How it tolerates snow on airfields and when flying in snow rain.
Compared to my Woodcomp Varia I would say :
- the take of performance is about the same
- climb is slightly better with e-prop
- cruise performance is about the same
- max level speed is about the same
- e-prop runs smoother (3-blade)
- fuel economy is about the same
- noise level is slightly less with e-prop
- e-prop is lighter
- pitch setting of e-prop is quite time consuming
- e-prop instructions are excellent
All in all very good nice propeller and wery good customer support.

Propeller mounted and tested! Pitch set at 18° as recommended on the identification sheet.
First impressions :
- much lower rpm at start up (1400 rpm) and without vibrations !
- more pleasant noise and lower decibel level
- higher take-off thrust at lower maximum rpm (5300 rpm) and impressive climb rate (vario at 5 m/s)
- reduction to 4800 rpm at 500 feet and levelling.
- full throttle and rev counter goes up to 5600 rpm! A little too much... pitch adjustment ?
- at 4500 rpm, the landing is maintained without touching the throttle.
I'm going to do a few hours of flight with this setting and I'll try a pitch setting at 18°6 for comparison.
Anyway, very impressed by the changes generated by the performance of this propeller!
A little marvel.

E-Props Durandal 100 vs DUC Swirl COMPARE on Savannah
Savannah Africa conducted a test on the E-Props Durandal 100 M to compare performance with the DUC Swirl on the Savannah S in order to establish which prop gives the better results.
ADVANTAGES OF EACH :
=> E-PROPS DURANDAL 100
1) The E-Props Durandal is lighter with lower mass moment inertia.
2) The E-Props is easier to set up the pitch more accurately. No knurling on the prop root.
3) The E-Props does not have an aluminium collar so is less susceptible to corrosion in a coastal environment.
4) The E-Props has a much longer time to inspection (2000 hrs as opposed to 800 hrs on the DUC Swirl)
5) The E-Props is smoother running requiring no balancing.
6) The E-Props results in a 13% shorter take off roll.
7) E-Props are a pleasure to do business with.
=> DUC SWIRL
1) The DUC Swirl is a more robust "looking" propeller more suited to a "Bush plane".
2) The DUC can be removed from the aircraft without having to reset the pitch [it is no more the case with the E-PROPS V20]
In conclusion we would say that the E-Props Durandal is the better propeller.

DYN AERO MCR 01 SPORTSTER
Product arrived safely, checked, assembled, ground and flight tested the same day.
Since testing in calm weather in the morning.
1st observation : it goes much faster than 4.800 rpm than with the EVRA, at the maximum continuous rotation speed of 5.500 rpm, the speed is slightly higher than 260 kmh, not bad for an 80hp.
No vibrations except below 2400rpm; although light.
So I'm delighted.
Small downside, the setting of the blades is laborious, it is almost impossible to be precise to within 0.1°, as the camera is so sensitive. Then the tightening systematically modified the tightening of one of the 3 blades, and always the same one. I still managed to obtain : 25.7/25.7/25.8

On the ground, the sound is pleasant, less vibration and the thrust is there with about 30% gain.
In flight, it is fluid and pleasant, the gain is about 5 km/h. to be checked after further tests.
The assembly and setting instructions are well written. no particular worries, you just have to be meticulous on the setting.
The take-off thrust is impressive. and according to colleagues on the ground, the sound is much more pleasant. so less nuisance for local residents.

As I told you I had a 2-blade propeller of a competitor's brand that I weighed 3.5kg when I took it apart. Your 3-blade weighs only 2.5 kg! Already a gain of 1kg!
Then the tests are irrevocable: with yours I take off in less than 150m, I climb to more than 1100 ft/min, I cross at 240 km/h. My Skylane is a real BOMB! I have to reduce not to go to the VNE!
I also noticed that with yours at the time of the engine shutdown there is no more 'clanc' when the propeller stops abruptly.

EVOLUTION TRIKES REVO
This is is my Revo with brand-new e-Prop propeller.
It's amazing.
Larry Mednick (EVOLUTION TRIKE) had told me to expect significantly increased thrust and monumentally smoother rotation (in particular, as compared to the two-blade Sensenich).
He was not kidding.
Smooth, yes. Very, very velvety smooth.
In fact, even starting and stopping the engine, because of the much decreased inertia content (I did not weigh or check specs to compare, but it feels like this assembly weighs one-third as much), there is far less jerking around as felt from the cockpit seat.
But in regard to thrust addition, it's practically out of this world.
With the Sensenich prop, Rival wing and 100 hp 912, the tendency at takeoff is the wing automatically wants to pitch high and (at least absent fighting it by pulling in pretty hard) you instantly go into a very steep and rapid climb.
This lasts for 2 to 3 seconds (maybe less; it always seems like these transitions consume more time than they really do), then the momentum kind of gives up, the nose drops down, and the climb is suddenly much more sedate.
With this e-Prop, I was amazed on the first takeoff. That steep climb just kept holding, and holding, and holding. It did not want to let go.
e-Props are made in France. They look like jewelry. They even have a characteristic which makes them almost like a variable-pitch prop at cruise.
Those Frenchies have done something amazing.

DTA COMBO
I was also seduced by the principle of "satisfied or reimbursed for 6 months".
The propeller of my delta trike having more than 1000h, I wanted to try the Excalibur as well as another one graciously lent by a manufacturer.
The pitch of my original propeller was set to have a maximum static rpm of 5400t. (912 80hp)
I've got the other two on the same diet. With the original propeller, as soon as I took off, I would gain a hundred more revolutions.
With the borrowed propeller, I was losing 100 rpm. With the Excalibur, almost 200.
I don't know the reason for the loss of towers, as the take-off distance is about the same.
But the Excalibur is the only one that makes me turn on my VNE light, set at 160 km/h, in full level flight. And I noticed a significant decrease in vibration at cruising speed. The Excalibur is also the lightest.
But it's not the quietest on my trike.
Since then, I've been riding a 100hp and swapped the Excalibur-4 for a Excalibur-6 (6-blade E-Props propeller) to shorten the takeoff distance. How wonderful!

Bearing 5000 rpm 3800 feet SAR = 219 km/h
Bearing 5200 rpm 3800 feet SAR = 231 km/h
WOT 5500 rpm TAS = 245 km/h
Vario max 3800 feet 1400 feet/mn

Sensations: less vibration at idle, smoother start and stop.
During the go-around (test 2) vibrations for the first 40 meters and then a quick stop of these vibrations as soon as the speed increases: maybe a stall of the airfalls.
I think the final setting will be around 25.4°.
Compared to the original propeller:
- gain of 10 km/h
- climb tx > 200 feet minutes
Less vibration at low rpm (<2500 rpm) and high rpm (>5250 rpm).
So rather positive all that!

It's the lightest propeller there is. It is very important to have a light propeller, especially to have a light ultralight and also to spare the Rotax gearbox. The low vibration is of great comfort for the pilot and passenger.
It is very solid, more than a propeller with metal leading edge protection. Tested on pebble tracks.
The performances are amazing with this aircraft, in max speed, cruising speed, takeoff and climb rate.
Great product, to be recommended.

Comparisons with my old two-blade Duc Flash propeller.
- Take-off : shorter ( about 50 meters less)
- Climb speed at full throttle 100 km/h: 1200 ft/min instead of 1000 ft/min
- Level at 2000 Ft QNH :
- 4800 t : 172km/h with 13,5l/h instead of 175 KM/h at 15l/h
- 5000t : 178 km/h with 15l/h instead of 178km/h (no change) and a consumption of 16,5l/h
- full throttle (5700 t/m): 200 km/h and 22 l/h instead of 192 km/h (consumption not measured).
The speeds are therefore slightly higher and the consumption (read and averaged on the flow meter) is slightly lower.
- Vibrations and noise: better than the Duc flash.
The E props propeller is therefore significantly more efficient than the 2-blade Duc Flash.

GROPPO NANDO TRAIL
My first objective was a shorter take-off. Widely achieved with 23.5°. I can't give comparative distance figures because the grass is a bit high but without wind, it's already spectacular with a go-around at 5500 rpm, without the inertia of the wood propeller. As for cruising, I gain 10 km/h at 4800 holes. A first setting with a larger pitch gave me a gain of 20 km/h, but I preferred to focus on takeoff. And indeed better rate of climb. And the trim is a little more stressed. The Trial's wide speed range is a delight, especially with a reactive propeller.

During our stay in Aspres during a gliding course, we made a comparative test with two WT9.
The goal was to see the difference between a Woodcomp propeller of the WT 9 from Serres (variable pitch) and ours.
On the real time comparative video (Aspres / Buëch, April 2016), our tugboat is on the right.
As the pilot, I can tell you this:
At the "pullout" we're pretty much the same.
On the taxi before takeoff, I pass slightly ahead.
We take off at the same speed, but quickly I gain altitude because I am faster than him.
During the flight towards Serres, I am in front and higher. Then he catches me thanks to his variable step.
At the end we landed in Serres.
This test was done in good weather conditions, little wind and a temperature of about 18°.

Tested in MTOW conditions on asphalt runway and the result is absolutely astonishing:
- Take off in 130 mt;
- Climb rate stands at approximately 1400 ft/m - 130 km/h IAS
- Cruising at 4600 rpm 195 IAS
- Cruising at 4800 rpm 205 IAS
- Full power at 5500 rpm 225 IAS and climb to + 800 ft/m to avoid exceeding the VNE.
I found that taking off and the plane cruising needs more right rudder than before,
I have noticed an improved agility on the pitch and yaw axes.
Comparing the performance of the previous Warp Drive 180 diameter:
Cruise: + 20 km / h IAS in 4600 and +15 at 4800 rpm
Takeoff: + 30/40 mt
rate of climb: +200 ft/m and +10 km/h (the first was 1200 ft/m at 120 Km/h ias)

For a smaller propeller diameter, shorter takeoff, better climb rate, less rpm for the same cruising speed and above all much less or more vibrations. The engine response is also much better due to the lightness of the whole. TOP TOP TOP TOP TOP.

At this speed, it behaves well and is pleasant. Some impressions of resonance in the transient phases probably due to its flexibility, which I did not have with my wood propeller.

PRO.MECC AEROSPACE SPARVIERO
I'd like to make a contribution by recounting my experience using an e-propeller with a ROTAX 912s on my brand-new Sparviero I picked up in Italy and flew back.
In another post, I said I was doing 120 miles an hour at 5000 rpm at 3000 feet. My propeller was throttled up to 25 degrees with the tool provided by e-prop.
This stall has given me the satisfaction of taking off from a variety of loaded, heavily laden terrains.
Indeed I had 230 km/h at 5000 rpm but almost impossible to take more revolutions when cruising.
It was at the urging of a pilot who wanted at least 5,500 rpm on the run, that I changed the setting to 22 degrees.
So I actually have more laps at takeoff (5300 rpm) but at 5000 rpm I fell to 200 km/h.
I don't feel like I gained any takeoff distance from the 25-degree setting. I don't feel like I gained any takeoff distance from the 25-degree setting.
It's the actual propeller pull that matters. I'm fine with 230 kilometers per hour at 5000 rpm, so I'm going to put it back down to 80. I'll put the throttle back on.
Now we're in the real world!

Here is my feedback on the E-Props after 175 h with a Durandal 100 in 170 cm on Savannah-S vs the DUC Swirl that I had before:
- Cruising speed TAS + 10 to 12 Km/h
- Vmax about 15 Km/h
- Climb rate + 200 p/min approximately on the 3000 to 4000 feet belt
- The machine pulls out faster, which allows me to remove the flap notch on takeoff on my runway.
- Vibration gain at 3200 t
- And very significant weight gain
- Steady-state speed 5600 t and 5400 in stages
I was the first to be surprised by the gains on all the parameters, but the gain in performance on my machine is undeniable...
The after-sales service and availability of E-Props is also top-notch.

DURANDAL-3
ASSO-AERO ASSO V
So we tested the propeller on an 'Asso V' (the same to Pioneer P300).
We were we are very satisfied:
Flight Conditions 1000' / 26° / Max MTOW
5500 rpm take off
4800 / 26 Map / Cruise (210 Km/h)
5600 rpm Full power (250 Km/h)
It means exactly what we expected i.e. the same performances that were in the previous Propeller (Ivoprop Ultralight variable pitch in flight), but without all problems of variable pitch propellers... And I think there is also a small range to improve it setting blades to 5400 in take off…

ALPI AVIATION PIONEER 300
I had an ARPLAST variable pitch propeller on my Pioneer 300. It broke down so I looked for another propeller. I hesitated to try your fixed pitch model because I didn't think I could get any performance with it on my aircraft. Your Satisfaction or your money back guarantee reassured me and I wanted to give it a try.
When I received the propeller, I didn't believe that such thin blades could pull the plane. But as I fly on a long and hard runway, I tested anyway, going progressively.
I must admit that I am very impressed by the performance of this EPROP propeller. I have the same take-off distances and cruising speed as with my ARPLAST VP. I don't know how you imagined it, but it works.
When I get to another field, people laugh, but it doesn't last when they see the performance.
I've gained weight and ease of use. I'm really happy.

LA SOCIETE
Congratulations to this determined and sympathetic team. I stopped by with a friend one Sunday morning in Sisteron: the 3 people in charge were at work to finish an urgent order. With good mood and passion they presented us their carbon propellers and their company. We were very impressed by the test benches and also by the beautiful workshops. It's encouraging: there are still dynamic high-tech companies in France.

EXCALIBUR-3
AIR CREATION TANARG
The test was done with Air Creation Tanarg Bionix13 wing.
*** Arplast:
RPM fixed point 5200
RPm full speed 5800
Max speed 170kmh
Cruising speed 115 km/h at RPM 5000
Max. climbing speed 80kmh. 4 M/S
Take-off distance m 80
*** Eprops:
RPM fixed point 5500
RPm full speed 5800
Max speed 170kmh
Cruising speed 115 km/h at RPM 4300
Max. climbing speed 80kmh. 6 M/S
Take-off distance m 75
I think is a very good result considering that the Arplast propeller model is what pushes more everything but is very noisy compared to Eprops.

Impressive propeller on its Eurostar. My friends had told me about it and I doubted but I am now convinced. All my performances are increased! Bravo and thank you!

DYN AERO MCR 01 PICK UP
Compared to the ground adjustable Arplast propeller I gained a little less than 50 meters of take-off distance and 150 to 200 ft in initial climb.
In spite of the installation of a larger wheel and fairing at the front, I gained about 15 kmh at 5100 rpm.
PLUS LESS VIBRATION IN FLIGHT at all rpm.
CONCLUSION: WHAT HAPPINESS!!

Super the 50 mm extension integrated into the hub. It's much lighter and easier to show than aluminium spacers. Performance at the top, like a variable pitch in flight. I love it too much! Thanks the eprops team

DURANDAL-3
PRO.MECC AEROSPACE SPARVIERO
The elements and the technique are evolving, especially with regard to the propellers. I have an e-props propeller on my sparviero and I CONFIRM that in level flight the rpm is lower than the take-off rpm (5500 rpm) at the moment. I know it's a bit confusing, it's due to the 'constant speed' profile of this type of propeller. In my previous setting I did not have 5500 rpm at takeoff, I had less and I could not get more than 5000 rpm in level, but I had 230 km/h at 5000 rpm at 3.000 feet Temperature 15°. Since then I have been able to test my aircraft, its 912s and my e-props in very different and new conditions for us: from 0 to 12,000 feet, from +15° to -15° in search of a climb, cruising for more than 1500 kms, taking off on hard ground and on dry or really wet grass, alone or with two strong guys like me + fuel + luggage. For me, having 230 km/h at 5000 rpm suits me very well, making a speed record at 5800 rpm for 3 min is not interesting. That said, I am not able to give you my intake pressure, even if my installation provides such a measurement, this function is not operational for the moment. As for the consumption, coming from the plane: it will always be less than equal punctures!

Mounting of an E-PROPS on a SAVANNAH in replacement of a DUC propeller.
With only one pitch adjustment, the DURANDAL allows to obtain :
- At takeoff and in climb: the same perfos as with the DUC when this one is set small pitch.
- Cruising : the same performances as with the DUC when it is set at large pitch.

With my savannah and an e-props, I have 5500 rpm static and 5350 in cruise, 5250 in climb.
Compared to the swirl, I gained in all areas: deco distance, acceleration in level, climb rate, cruise and Vmax. Only the consumption has not been checked for the moment.

Here are my results on my Zephyr:
PA: 26 at 4800 rpm
PA: 27 at 5500 rpm
PA: 24 at 4300 rpm
tiered
4000 rpm : 180 km/h
4500 rpm : 210 km/h
4800 rpm : 225 km/h
5000 rpm : 240 km/h
5500 rpm : 260 km/h
Max in beam: 5600 rpm : 265 km/h
Decorating distance almost identical to the wood-comp but with the E-Props I gain in climbing and cruising speed of 20 Km/h with the same engine speed.

SATISFIED OR YOUR MONEY BACK 6 MONTHS
even if I was not completely satisfied with this propeller that I returned under warranty, there was no problem to go > 5500 rpm, it just takes a bit of patience and rigour
The company is very correct, it should be pointed out concerning the recovery of a propeller.

FLIGHT DESIGN CTSW
I'm very happy with my propeller!
I gained at least 15 km/h by changing my Neuform. And at the same time I take off shorter. I have gained at least 300 ft in climb! And what comfort! The stop of the Rotax is much softer. So I keep it!

EXCALIBUR-3
MAGNI M16 TRAINER
As planned, I installed your propeller on my Magni M16, and the change is amazing compared to the Arplast!
Almost total disappearance of vibrations, no cavitation at power-up (this phenomenon had appeared after the LAD injection was installed when I had to add pitch), much quieter (in the machine and from the ground), and an incredible lengthening!
You just have to let it gain speed and then progressively reduce the rpm and the machine keeps its speed!... I gain about 200 rpm of engine rpm at the same speed compared to the Arplast.
Overall, the operation is much smoother, which my wife likes very much. The Arplast provided much more brutal ("virile"?) sensations with the surge of power brought by the injection, but this power is now better controlled by the e-Props!
We are thus very satisfied and we thank you for the quality of this propeller!

We received the propeller yesterday and mounted it on a P-92 100HP.
We are very happy with the incredible performance of your propeller! To give you an idea, at 4.500 RPM we have a speed of 100 Kn/h. and at 5000 RPM we have a speed of 120 Kn/h.
Thanks again for your service!

DYN AERO MCR 01 ULC
On my MCR ULC equipped with a rotax 100hp, I have installed an E Props propeller since the end of July; it is the Durandal 100 S 1.60m.
I used to have a 3-blade 1.60m Woodcomp, rather set at high pitch.
It's really bluffing.
I won on all levels: short takeoff, high cruising speed (a good 240 to 5000 rpm), it is light (less than 3 kg) and very flexible on the engine = no couplings.
We must be close to the performances of the ARPLAST PV 50.
Note that the E-Props is only worth 1800 € against 5000 € for the PV 50.

I must confess that I didn't believe in your commercial arguments - but with the money-back guarantee I wasn't taking any risks - and I was curious to see what your approach, so different from the competition, was like. Your blades are so thin - it's amazing.
After testing and comparison - see attached xls file - I can tell you this: you've made your move.
Not only do I keep this propeller that gives me great satisfaction, but I'm going to advertise it to you. I am glad to see that it is still possible to innovate in our country. Keep up the good work.

On my A22 used in society for first flights, I see the difference compared to the Kievprop and also to the Duc I had before.
I consume about 8% less fuel and the rate of climb is 300 ft better. The propeller is very solid on the pebbled runway.
You just have to glue the hook of the instrument better (it comes off). [the model of digital protractor has been modified since]

DYN AERO MCR 01 SPORTSTER
The propeller suitable for the SPORTSTER is the 155 cm diameter DURANDAL-3 with adjustable pitch on the ground.
The test results are equivalent to those obtained with an ARPLAST PV50 Constant Speed propeller.
Perfect balancing. Weight propeller + cone + fasteners = 3,3 kg
Climbing rate: alone on board, I have 1600 ft/min, two with a 100 kg passenger, we have 1000 ft/min.
At 250 km/h, consumption = 16 l/h.
