Great videos but I urge you to have Roger repitch your prop so you don’t damage the engine. Your RPM is way too low on takeoff. 5200 minimum per the Rotax manual. Talk with Roger and he’ll explain it even better. You are over stressing the engine/crankcase and really hurting your climb rate, cruise speed and fuel economy.
Yeah, thanks for the heads up. Roger and I talked about that during the last annual. I haven't done the test he suggested, but will make sure it is addressed during the annual next month. Thanks again.
