The propeller has two types: Direct drive and Belt reduction drive. It’s direct drive type.

The VP3A variable pitch propeller is that can automatically (or manually) change the blade angle according to the flight speed and altitude during flight. Variable pitch is to change the installation angle of the blade section, the purpose is to make the section have the most favorable angle of attach, so as to improve the efficiency of the propeller. It has the characteristics of improving propeller efficiency, improving engine utilization rate and flight performance according to the engine height characteristic curve, and easily matching various working conditions (takeoff, climb, cruise, speed etc.).
