I have put an E-prop on my Alto TG 912. It’s great, get an extra 4-5kts cruise and awesome climb rates. I previously had a Kiev prop

e have tried Glorieuse on ALTO and the performance is really excellent.
So far, our experience is that your DURANDAL ground adjustable pitch propeller is almost as good as other brands Constant Speed propellers, and that your GLORIEUSE Constant Speed propeller goes far beyond other Constant Speed propellers.

Did my first flight test in the Alto this morning with the new E-prop fitted , I thought I had a great propeller, then I got an E-prop, it is amazing.
So much quieter than my previous propeller and smoother in flight. A neighbour near the airport mentioned to me that he could no longer hear me take off!
I managed 5250 RPM so I still have to fine tune the pitch to achieve 5500 RPM.
Even at 5250 I managed to achieve a very impressive 125 kt TAS. My previous prop would only achieve 108 kt at the same RPM. Throttling back to 4800 RPM I still achieve 114 kt TAS with only 16.4 Litre/hr of fuel consumption!
Climb rate with 70 litres of fuel on board and a passenger was still an impressive 1000ft/min at 60kts IAS.
No noticeable difference in takeoff roll distance.
The propeller response feels much more progressive with the E-prop.
I am VERY impressed. I wish I had an E-prop fitted sooner !
Currently set at the recommended 27 degrees of pitch and achieved 5250 RPM so will adjust to 25.8 degrees (200 RPM = 1.2 degree adjustment) and see what RPM and speeds are achieved.
A couple of pictures attached and my first flight test data for your reference.
Thank-you to you and your team for such an amazing propellor !

Indeed, your propeller is incomparably better than the Fiti on the Alto. In every aspect. I am extremely happy with my purchase and I advertise it to all my friends.

The best propeller for the ALTO. I have tried several models from several manufacturers. The Durandal is exceptionally much better. I am very satisfied and I advertise you everywhere. You deserve your success, keep it up.

I gained 20 km/h by changing my wooden propeller by this carbon eprops propeller and it is also 4 kg lighter. Thanks to your team.

The E-Props is perfect on the Alto: powerful, light, pretty. An excellent set.

Incomparable! I had the original Fiti before, and with the Eprop, it's simple, I don't recognize my plane anymore. All, I mean ALL the parameters are better and especially the maximum speed which increases by 10 kt!
I couldn't imagine that changing the propeller would change the plane so much. Thank you Eprop for offering the Satisfaction or your money back guarantee because it allows you to try without taking any risks. Eprop is a company at the top and very attentive to its customers' needs, even after delivery.

Thank you for your great job.
