Master Airscrew RC Propeller 12x5 - MAS1250

The Master Airscrew MAS1250 is a 12x5 RC propeller designed for fixed-wing electric aircraft requiring a 12-inch diameter prop with a 5-inch pitch. Master Airscrew propellers are a well-regarded choice among RC fixed-wing pilots, offering consistent balance and reliable thrust output for sport flyers and larger electric models. The 12x5 pitch specification makes this prop suited to mid-to-high torque brushless motors where a moderate pitch is needed to balance speed and efficiency.
