Master Airscrew 9x4 Plastic RC Propeller - MAS9040

The Master Airscrew MAS9040 is a 9x4 plastic propeller designed for fixed-wing electric RC aircraft requiring a 9-inch diameter, 4-inch pitch prop. Master Airscrew produces propellers trusted by RC flyers for consistent balance and reliable performance across a wide range of electric powered aircraft. The 9x4 size is a common choice for mid-sized fixed-wing models where a balance of thrust and efficiency is needed at typical electric motor RPMs.
