FLIGHT DESIGN CTLS

CTLS : a comfortable and agile ultralight, excellent visibility, high cruising speed, impeccable manufacturing quality, reasonable acquisition and operating costs.
The CTLS is approved with E-Props propellers and it's with these propellers that they offer the best performance.

I received my propeller. Well packed, smooth delivery...
I mounted it yesterday on my CT (Rotax 89 hp Injection) following the assembly video.
I set the pitch to 24.30 as recommended in the video. On Saturday, I gave it a try, but the windy conditions weren't conducive to a serene test.
Today the wind died down and I was able to test the propeller in good conditions.
The results are truly impressive: the CT takes off (at 5078 rpm) in 150 m less (at the very least), climbs 400 Pds/min harder, but it's above all at cruising speed that the progress is most spectacular (160 km/h at 4100 rpm, 185 km/h at 4650 rpm, 205 Km/h at 4900 rpm. I've finally got the performance I was hoping for from a CT. Previously, I was struggling to reach 180 Km/h at 4900 rpm and 200 Km/h at full throttle (at 5700 rpm!). I think the setting of my previous propeller wasn't too bad: it took off at 5050 rpm, struggled to keep that speed in the climb, and screwed up when levelling off, not a 'constant speed' behaviour at all! In the process, the CT lost 6kg in the nose (-4kg propeller and -2kg with LiIon battery) without too much impact on the balance.
Of course, the propeller isn't cheap, (but it's comparable to other French manufacturers...) but I feel like I'm getting my money's worth!
It remains to be seen how it will hold up over time, but I think there's now some hindsight.
So, thank you e-props for making such good propellers!

As the pilot of a CTLS equipped with an E-Props propeller, I have to say that I'm extremely satisfied with its performance. The combination of CTLS and E-Props has really exceeded my expectations and is a real pleasure. The combination of outstanding performance, light weight and noise reduction has made me a satisfied and confident pilot.
I highly recommend E-Props to all CTLS owners.

Still loving these props on our CTLS's !
Have over a 1000 hrs on one and 700 on the other.

A 3 blade propeller of 2 kg; I did not believe it. Bravo the carbon. Perfect efficiency, very aesthetic propeller. I have now 170 hours of flights with this propeller and I am still delighted. It is a real advantage for my CTLS.

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.

We are having great success with your props on Flight Design CT and everyone flying them has great reviews.

Much better than my old heavy and fragile Neuform. Glad to know that the Eprop is now OEM at Flight Design. It's about time they went with better material.

On my CTLS 100hp, the eprops propeller is very powerful. It allows short take off and high cruise speed: 220 km/h. I am very satisfied.

Thank you for letting me know. You and your company have been wonderful to work with. You know what customer service is.

To have changed a Neuform by an Eprops on a CT, it is obvious, the eprops is much more powerful in all fields and the hub and spinner assembly is of a very high quality. The eprops staff is also very competent, reactive and friendly!
So I bought a second Eprops for another machine and I'm still happy with the quality and performance!

We received our new E-Prop and have now flown it on one of our Flight Design CTLS aircraft for about 30 hours. I have to say I am very impressed with its quality and performance! The climb rate and takeoff performance has been enhanced, cruise performance is similar, and it runs very smooth.
We will likely order another for our second CTLS soon!
Attached is a picture I took during unpacking of the product, it shows one of the spinner backplate rivnuts dislodged from the plate. Not sure if it occurred during shipping but just wanted to make you aware for quality purposes, it was a easy fix and no issue.

The cone of the new propeller for my CT LS is perfect: longer than the 1st cone. It's much prettier that way. The propeller has the right parameters and with its titanium shielding it is very strong.

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.

I've just come back from a series of test flights today because the weather was nice at home. I am hallucinated by the performance of this propeller! Nothing to do with my Neuform which has more "normal" blades than yours. According to my indicators I had to gain 15 km/h in cruising speed and the ultralight takes off shorter than before! I will send you all my test results in excel file. Congratulations to your engineer Jérémie!
