I am using the Hartzell 83" Trailblazer composite propellor. This was tested by Mark Goldberg of the Bearhawk factory (AviPro Aircraft). Everyone I spoke that has flown behind this prop LOVES it! Very lightweight and exceptional performance.
Hanging the prop is fairly straight forward. Hartzell technical service department was very helpful. I confirmed a few things with them from the manual. Prop governor installation and set up, prop hub orientation, safety wiring, etc. The manual tightening the prop hub to 40 ft lbs each bolt. There is a bolting sequence to be followed. You can't do it without a propellor wrench. Hartzell sells propellor wrenches, but the Ultimate Propellor Wrench works best! https://antisplataero.com/products/ultimate-propeller-wrench
