Besides greatly improving the aesthetics of your airplane when parked on the ramp, reduced vibration and noise are one of the biggest advantages of a 3 blade propeller. The 3-Bladed McCauley Propeller D3A34C401/90DFA is offered for your airplane in 5 choices of diameter. The extra blade adds static thrust, which improves take-off acceleration and climb. A three-bladed prop lessens the vibration and noise levels in the airplane in a way most people find more comfortable. Contact Air Plains for more information.
