ZENAIR CH-601

DURANDAL-3
I thank you for your good advice that allowed me to change my Warp-Drive propeller for your E-Prop on my Zenair 912. I am extremely satisfied, and of course there is no question of returning it. I have seen the speed increase by 20 km/h. The comfort of flying is now perfect.
Thank you for these innovative propellers which bring us a lot.

Impressive propeller on my 601.
I had a wooden propeller on my Rotax 80hp. I changed it for a Warpdrive. It was already better.
But now, the difference with the Warpdrive is really noticeable: I gained at least 60 ft at rolling, 300 ft/min in climb and 8 kts in cruise.
The E-Props are more responsive and lighter. The carbon spacer system is very ingenious and helps reduce vibrations. In short, I am conquered and I promote it.

This ultra-light propeller leaves the other brands (Duc, WarpDrive, Peszke) far behind. On my Zenair 601 912, all flight parameters increased. The Durandal is the perfect product.

Try this am of the e-props propeller.
First impressions therefore because no reliable figures with a wind of 20/25 kts in altitude.
In any case zero vibrations, a plane climbing trees, a playful 220 at 4900rpm and a max rpm of 5550rpm at 240 which still rises timidly I think I'm good!
For those who say that this propeller brakes less on approach, just pull on the stick and don't forget the role of a downwind leg.

A good propeller for my CH 601, better than the Duc Swirl and the Warpdrive I had before. But the Warpdrive was vibrating, speed was not very good, and the Duke was taking a long time to take off and climb. The E-Prop is better for all parameters.

We have experiences of the DURANDAL-3 propeller on my Zenair and the one of my best friend. We would like to share :
– engine runs smoother
– Take off performance and climb performance are better, by 10% (appr.)
– Fuel consumption appears to have decreased by about 8%
– The noise level is much more quiet.
– The customer service is perfect good, thank you very much.

Flight test after 7 hours of local flight operation.
Zenair 601 XL 912S take-off weight about 460 Kg.
Propeller E-PROPS DURANDAL-3 3-blade in 170 cm equipped with its carbon cone in 230
Conditions of the day : Temperature 11°, less than 10 km/h wind, 4000 feet QNH, hygrometry not measured, 5000 rpm 24 inches of intake.
Three branches at 120° of about 100 km each.
Maximum speed in level 235 km/h.
GPS reading: 306 km in 89 minutes, an average of 206 km/h. Fuel consumption 15.5 L/h
The old two-blade variable-pitch propeller in flight did not perform better in these conditions.
PLEASE...
Continued: Good evening, Yesterday nice flight and what a satisfaction with your E-PROP propeller.
A marvel (French ) and a purchase that I do not regret!
I should have thought about it long before... Good evening and see you soon I hope.
