GLORIEUSE-3
This morning I tested the Glorieuse propeller on my BRM Citius 100cv. It exceeded my expectations!
The performance speaks for itself: 185 km/h at 4,800 rpm, 25.5 PA, and an insane climb rate—four digits! Truly top-notch.
The takeoff distance is also impressive. A pilot waiting at the runway holding point even called me on the radio to ask what I’d done to my microlight!
On landing, same story. Before, it was hard to descend smoothly below 100 km/h. With the Glorieuse, I can do whatever I want.
It’s a no-brainer!

My co-owner and I are very satisfied with this epro propeller on our BRM Citius. We're delighted with its responsiveness, and there's no vibration. The carbon parts are a real success. We warmly recommend it.

This morning with the Durandal on Citius 912ULS, we had 191 km/h at 5000 rpm on a check flight before delivery

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!
