Excellent propeller for my Citius. I really appreciate Eprop. I won on all points and I have no more vibration. The sales department is very friendly and very attentive to the pilots. I predict a great success for this company.

Thank you for your welcome and your availability. We gained a lot by changing propeller: At least 10km/h in cruise.

A first feedback with a propeller set according to EProp data (my Duc was a priori set according to DUC data: 23° (from memory) with maximum speed at go-around of about 5,200 rpm):
- a much higher take-off power with a shorter taxi and a higher rate of climb (+200 ft/mn)
- to have the same cruising speed you need more turns than with my Duc but a priori the AP must be a little lower (consumption a little lower)
- the EProp argument with the same rotation speed in climb and cruise (full throttle) is checked
- less vibration
- a much softer stop for the gearbox.
In fixed point I have 5,500 rpm then 5,400 in initial full throttle climb and I will, in the next few days, slightly increase my step to go from 24.3 to 25 / 25.3
These data are from about 5 hours of flight with this new propeller.
EProp gives -100 rpm for + 0.6° of pitch. To be refined with additional tests.

Same take-off distance as with the original propeller, and + 15km/h cruising speed!
