Aerostar products, known as good quality airplane components brings its accessory line full circle with their series of wooden propellers for electric and gas applications. These high quality wooden propellers are precision machined for efficiency and great balance straight out of the package. Pre-drilled with a slightly under size propeller shaft hole, this allows you to ream to the exact diameter of your electric motor propeller adapter. For added safety and good looks we have painted the tips of each propeller to better see the prop arc when your motor is running. Each propeller is then clear coated to seal the wood providing years of use.
Aerostar offers a wide range of sizes and pitch combinations to suit most airplanes from parkflyers all the way up to giant scale airplanes.
