DYN AERO MCR 4S

The MCR Evolution 4S is the only four-seater aircraft combining speed (240km/h), STOL performance and high payload (395kg).

GLORIEUSE-3
This Glorieuse is exactly what I wanted for my MCR4S. Ultra-light and really high-performance, with great responsiveness when you go back on the throttle. I love it and don't want another one.

GLORIEUSE-3
We've just fitted a Glorieuse propeller to our MCR, and the drop in fuel consumption is amazing. Before, we were burning around 18 litres/hour at cruising speed. Now, we're doing the same flight with just 16 liters/hour. What's more, it's light and quiet. The best of the best.

GLORIEUSE-3
I've just fitted a Glorieuse to my 4s rotax 914.
I had an e-prop durandal at high pitch, so take-off and climb performance was a bit sluggish.
With the Glorieuse, I'm back to fantastic take-off and climb performance, taking off at 700 kg in 180m, climbing at 800ft/min at max continuous and 160 K/H for 10 min as requested in the test flight program. With the 914, I kept this climb rate for the whole 10 min, and no CHT or oil overheating.
Engine cooling is no longer a problem, as it sometimes was with the Durandal.
Cruising speed of 220 K/H at 75%, as with the Durandal, which was stalled at high pitch, so it's normal.
The empty weight is now 368 kg (+1.4 kg), with the center of gravity at 22%.
I did the assembly in Sisteron at e-prop, (more or less 6 hours of work) and the test flight also in Sisteron, with a ground temperature of 24 degrees.

DURANDAL-3
The MCR4S of the NGO Pilotes Volontaires that we use has been equipped for a few months with a new Rotax 912S (instead of the 914) and an E- Prop.
This assembly made by Se.Aviation gives us satisfaction, we carry out missions of 6/8 hours off the coast of Libya thanks to the long range tanks and note a consumption of about 17l/H => or with 200l an autonomy of 12h! ( much more than our bladders ?)
I was inspired to decide on these modifications by the always enlightened advice of Michel and Dominique de Cholet.

DURANDAL-3
As agreed, you will find in PJ the results of the test flights carried out with the MCR 4S as part of the replacement of the original propeller by a DURANDAL 100S 155cm.
The results are in line with what we expected.
