Details
Built for fixed-wing aircraft and VTOL tail propulsion, the F5055 delivers stable output in a compact 50mm class motor.
A detachable structure makes maintenance simple while the vented housing helps move heat away during high-load runs.
Pairing options like a 15×8 prop highlight the motor’s torque and efficiency for aircraft propulsion setups.
High-temperature copper windings (rated to 220°C) support reliable performance when sustained power is needed.
Dimensions, mounting pattern, and test data are provided to help match the 250KV or 550KV version to your voltage and prop.
