MCR 01 is derived from the COLOMBAN MC-100. It is characterized by high performance at a relatively low purchase and operating cost.
A perfect propeller for the MCR.
The results exceed those achieved with the PV-50. The cooling is perfect thanks to the special profile of the blade. The eprop design office has worked well.
My MCR with Glorieuse = the best performance ever, very light propeller, very reactive, no vibrations, a flexibility of use never equalled, and it brakes on approach. I like it and my MCR too!
I take this opportunity to inform you that we are fully satisfied with the Durandal 100 mounted on our MCR 912 s for almost two years.
After a few tests, we have adopted a compromise which allows us to take off on 200 m in two and to take 210 -220 of cruise between 5000 and 5200 rpm. Whatever the flights, we are at about 16 to 20 liters per hour.
With the three-blade E-Props, full throttle in low altitude level, I get 5600 rpm.
Cruising at 3000 ft, I have a speed of 250 km/h at 5000 + r/m and a fuel consumption of 15 l/h.
What could be better?
Competition propeller : I confirm 2.3 Kg, 1700€, 650 FT/mn and 120 Kt at the MTOW. Just happiness!
Mr Colomban may be proud to have designed, with the MCR UL, the fastest fixed gear ultralight (by far).
For my part, equipped with a propeller E props fixed pitch, I fly, alone on board, at 245 km/h at a speed of 5000 rpm and consumes 16.5 L/h.
On my ULC 100CV I have a 29° angle on the Durandal 1.6 m.
I'm set rather big step, the cruising speed at 5000 tr altitude 1500 feet is 245 km/h (see 250 km/h in cold weather)
I take off relatively short: 150 m alone on board (I have a 350 m runway, never had any problem at take-off)
I wouldn't change my pitch, that's fine.
Indeed, my first tests started with the E-Prop instead of the MT Constant speed propeller and the first results are very encouraging, no noticeable loss in take-off distance, climb performance and cruising speed with the propeller set at 28°, less vibration too, and I've gained over 30 pounds (I may have trouble with the aircraft's Center of Gravity).
I am therefore very satisfied, and I can send you, if you wish, a table of the performance measured on my ULC MCR.
Bravo again and thank you!
First flight today, in Grenoble, with my MCR ULC 80 HP equipped with its new DURANDAL 80 S.
I had a bad conscience to be unfaithful to my beautiful EVRA but after this flight I don't feel like it anymore: my DURANDAL and I are going to do great things together...!
On my MCR ULC equipped with a rotax 100hp, I have installed an E Props propeller since the end of July; it is the Durandal 100 S 1.60m.
I used to have a 3-blade 1.60m Woodcomp, rather set at high pitch.
It's really bluffing.
I won on all levels: short takeoff, high cruising speed (a good 240 to 5000 rpm), it is light (less than 3 kg) and very flexible on the engine = no couplings.
We must be close to the performances of the ARPLAST PV 50.
Note that the E-Props is only worth 1800 € against 5000 € for the PV 50.
