Just MHO but Ivo should have made their prop so that it twisted to flatten the pitch for take off and relaxed into the cruise position. The rotary has enough power for most of the airframes builders talk about installing it in, that a minor degradation of in takeoff and climb could be offset. Let's face it, cruise performance is where the rotary can make up for its high BSFC. I'd much rather go from 1000 fpm to 800 fpm climb than lose that 10 knots at cruise. If I do get the cruise lose I'd rather it came from my hand on the throttle. I save lots of money by using 65% power, our club charges by tach time.
