FLIGHT DESIGN CT2K

FLIGHT DESIGN CT2K : an ultralight from the leading German manufacturer of leisure aviation. A spacious cabin. An interesting autonomy. Irreproachable flight qualities and passive safety by its design. Ease of use and robust design.
The CT aircraft are approved with E-Props propellers.

I received my propeller, well packaged, smooth delivery.
I mounted it yesterday on my CT (Rotax 89 hp Injection) following the assembly video.
I set the pitch to 24.30 as recommended in the video.
The result is really impressive: the CT takes off (rpm 5078) in 150 m less (at least), climbs 400 Pds/min harder, but it's especially at cruising speed that the progress is most spectacular (160 km/h at 4100 rpm, 185 km/h at 4650 rpm, 205 Km/h at 4900 rpm.
I've finally got the performance I was hoping for from a CT. Previously, I was struggling to reach 180 Km/h at 4900 rpm and 200 Km/h at full throttle (at 5700 rpm!). I think the setting of my previous propeller wasn't too bad: it reached 5050 rpm at take-off, struggled to keep this speed in climb, and screwed up in level flight when the engine ran away, not an 'ESR effect' at all!
In the process, the CT lost 6kg in the nose (-4kg propeller and -2kg with LiIon battery) without too much impact on the balance.
Of course, the propeller isn't cheap, (but it's comparable to other French manufacturers...) but I feel like I'm getting my money's worth!
It remains to be seen how it will hold up over time, but I think there's a bit of hindsight now.
So, thank you e-props for making such good propellers!

Wow, this propeller is very impressive! I feel like I've changed aircraft. We fly faster, we take off shorter and we climb much better.

We already installed some ones (Durandal models) on CT2K and also on a new CTLS Super for our Flight school. With large satisfaction. AVIARE, Italy

I don't recognize my CT2K anymore: it takes off shorter and flies faster. I have to make comparative measurements, but I can already say that the difference is noticeable. It took a little bit of time to get the right setting; now it's ok, thanks for your help and congratulations for your quality equipment.
