ZENITH AIRCRAFT / ICP CH-650 Ei Rotax 912S gear ratio 2.43
Zenair 650EI or 650ER: the low wing ULM with the best ratio/price quality for leisure or towing. This model received the Kenblatt (German ULM certification: DAeC-Kennblatt 61196) in 2016 with a 3-blade E-Props propeller.
I am not a test pilot so I don't know if the performance is better or not from my old Duc propeller.
What I can say is that the new Eprops propeller does not vibrate. I had a vibration at 4800 rpm with the Duc. No more vibration with the Eprops. What a comfort.
Congratulations to you for your innovations. The explanations you gave about the unusual shape of your propellers convinced me. My Durandal propeller on my Zenair 650 Ei is probably the best.
This propeller gives the full potential to this exceptional machine that is the CH-650. Good job E-props.
Durandal is a good choice for the CH-650. It is very easy to mount with the adjustment tool provided.
3-blade E-Props on our CH-650.
We chose this propeller because the propeller and cone are very light.
The E-Props weighs 2.5 kg and the complete cone 0.5 kg.
The pitch setting you gave us gives 5450 rpm full throttle in level flight.
Climbing speed: 90/100 km/h.
We are satisfied.
Very silent propeller with excellent performance.
