Catto Propellers designs propellers for a variety of aerobatic styles that are strong enough to withstand the demands of advanced aerobatics. With a light weight fixed pitch, the engine can run up to 3000 RPM providing the same performance of a constant speed while reducing crankshaft stresses by taking an average weight savings of 40+ pounds off the nose.
