We finished our FAA required 40 hour flight testing last week and the Airmaster prop has been a joy to operate. The initial installation was simple and well documented.
The Airmaster propeller takes full advantage of the 914’s full takeoff power to 8,000 feet and full climb power to 16,000 feet pressure altitudes with 75% cruise power at even higher altitudes. Cruising at 17,500 feet the Airmaster allows a 32% faster cruise than a fixed pitch prop at sea level."
