Rotax states “Take off RPM at WOT (wide open throttle) should not be below 5200 rpm to avoid over loading the engine.”
Having set my prop pitch to the 71.4 degrees specified in the Van’s KIA, my WOT takeoff rpm tends to be in the low end of 5,100 - 5,150 rpm range. Flattening the prop pitch to 72.0 degrees has resulted in little change of the WOT takeoff rpm.
What pitch have people set their two blade propellers to on their 912 ULS engines to meet this requirement?
Thanks.
