An in flight adjustable prop is something like an automatic transmission in a car. You can better match the takeoff, climb and cruise performance for your engine and airframe. It works great on a 215 horsepower T-34B. However, a KR-2S application may be somewhat unknown. Down side is the increased weight and complexity plus there is another control to properly use. You can also easily destroy an engine with improper use of the prop pitch control. Some engines, such as the direct drive VW, will not long tolerate the heavier weight and gyro loading of a controllable pitch prop trying to break the crank shaft.

Is it wirth the weight and money? Or should I buy next year(S) a ground adjustible 3 blade. I planned a 95 HP engine. Stef Stef and Ted are building the KR-2S see http://www.masttotaalconcept.nl/kr2
