E Mail Within the last few years both Hartzell and McCauley Propeller have designed and tested new technology propellers. With this advance in technology we are able to install these optional propellers on a variety of aircraft. These STC Kits will include new Propeller(s), new Spinner(s), all Mounting Hardware, and the necessary STC Paperwork and Instructions.
Select the Aircraft Manufacturer name to see a listing of the Kits that are available for their aircraft. Please note these listings cover the popular kits and other STC's might exist for these installations. We try to offer the highest quality kit available and can recommend those propellers listed.
