Upgrade your RC airplane with the sourcing map propeller adapter spinners. Designed for brushless motors and speed controllers, these 3.17mm aperture and 5mm output axle adapters give you a secure connection between motor shaft and propeller. Made from solid aluminum, each spinner is lightweight yet strong, resisting wear and vibration during high-speed flight. The silver finish adds a clean look while the precision machining ensures a perfect fit, so you can swap propellers quickly without extra tools. Because they are small and easy to carry, the three-piece pack is ideal for on-the-go builders and hobbyists who need a spare or want to experiment with different prop sizes. Installation is as simple as unscrewing the old adapter and threading the new one onto the motor shaft-no drilling or modification required. Whether you are tuning performance or just replacing a damaged part, these adapters provide reliable power transmission and help keep your aircraft balanced and efficient.
