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 (80 inches to 88 inches in diameter, 84 landplane and 88 floatplane maximum). 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.

Another practical advantage of the three- blade is reduced maintenance. This comes from the reduced rotational stresses from the shorter blades, which can make a real difference, particularly if the conversion is replacing a two-blade propeller with blades more than 82 inches long.
