AEROPRAKT A22

The A22 : the all-terrain airplane! More than 1000 A22 are flying around the world.

I flew this recently and trained a pilot converting from gyro. Smooth - great on climb - great in cruise. My next prop will be an eprop.

E-Prop all day! My last plane had a much heavier prop and can’t be compared to the E. Smooth, quiet, and a few more MPH!

I’ve done around 100hrs on my new e-Prop and the performance is exactly as advertised. Just get one!

Client installed it on his A22 and he got about 5-10Kts more on Cruise (power pitch setting) .. Same as on our A22LS , first notable is vibrations one was used to or thought it's normal are less, and noise are less ..
Take off distance - depending on your preferred pitch setting- it's the same.
Did about 200hrs since Dec 2022 on E-Props with A22 which includes: flight training, bush flying, anti poaching flights where all scenarios were thoroughly tested like low and slow, short distance take off's 60-100m, gusty winds of 35knots in 39°C temp where you on your limits 90% of the time when it comes to power available and power needed etc. and the list goes on.
To date, I couldn't find anything that's of concern..

Very impressive this in-flight variable pitch propeller. My A22LS is completely changed. I take off in less than 50 ft and fly up to 117 kts. The propeller is responsive. The assembly is easy.

A nice all carbon propeller for my AEROPRAKT A22. I am very happy because it pulls hard while being very light. The engine appreciates it. To be recommended to all A22 pilots.

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.

I now have a A22L2 + Rotax 912s 100hp + Eprop Durandal Titanium. I think I have the ideal aircraft for my use. It climbs at more than 1000 feet/minute and flies at more than 180 km/h. Safety and speed.

As agreed, here are the parameters of my A22-L2 Aeroprakt with your Eprops 3-blade:
* very short take-off. I couldn't measure it, but it's shorter than usual.
* climb to 900 ft/min
* cruising at 4800 rpm speed TAS 158 km/h
* at full power I get 5,560 rpm which gives a maximum speed of 184 kph TAS.
* no vibration
* noise in the cockpit very reasonable, correct without headphones
Thank you for your good advice. The setting of my propeller seems perfect.

That's a great propeller! It's very thin, but it pulls really hard. I'm happy with the French excellence. Your sales department is also very attentive: I had lost a screw from my spinner - I received a complete set in 2 days. Thank you very much!

Thank you for your job. Good prop, very smooth, good efficiency. So nice with the fine blades.
My friends told me that so fine blades cannot give thrust, but they were wrong! And now they all want this prop.

Tests of an e-Prop propeller (170cm) Durandal on AEROPRAKT A22L2 / Rotax 912S)
Weight with screws and bushings 2 900g (-2500g)
Ground clearance: 35 cm ( = )
Setting: 20.6°.
5,370 rpm at take-off 120M on high and wet grass (= probably lower in identical conditions)
Tx Rise 800 ft/min at 120km/h (+150ft/mn) 2 POB
Tx Rise 950 ft/min at 120km/h (+300ft/mn) 1 POB
180 km/h at 5,200rpm (+15km/h)
RPM drop during cut-off tests -30 rpm
Noise pollution to be validated by measurements but lower (inside and outside)
Significantly less sensitive vibrations
Really great work.
Congratulations to this French success, and it is beautiful!

This propeller is the best compromise on my A22. Light, powerful, solid. Thanks to the team for the help in reassembling it, and a weekend.

Since May 2014, I have been using a Durandal 3-blade propeller purchased from you on 28/12/2013.
It is installed on a ULM A22 Vision with a Rotax 912, and after more than 100 hours I am satisfied.

Have changed my kievprop for the 3blades durandal : absolutely AMAZING!!!
I have a NEW aircraft now. So smooth and efficient and nice.
How are you doing that guys???
THANK YOU so much!!!

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]
