Reliable, Accurate, Safe!

Overview

 

The PowerMax is a three-blade tractor in flight adjustable aircraft propeller. The aluminum alloy hub consists of top and bottom flange with lid. The blade adjustment mechanisms are located inside the hub. Increasing of the blade angle is done by the actuator. For the opposite direction, the blades are adjusted through the resistance of spring located inside the hub. The carbon fiber blade has got an steel root part and is mounted onto the hub by a pair of axial bearings. The actuator is located outside the hub, above the engine reduction unit, and controls the blade adjustment by a hollow axis of the reduction unit and the propeller.

The propeller is suitable for the following engine types:

  • ROTAX 912 UL - 80 HP

  • ROTAX 912 S - 100 HP

  • ROTAX 912 iS Sport - 100 HP

  • ROTAX 914 - 115 HP
