Brushless Motor for FPV Drone FT 3115 800KV 6S–8S

The FT 3115 800KV motor is designed for large-scale FPV platforms and 9–10-inch long-range builds. The combination of an oversized stator and an 800KV rating provides high torque, allowing the motor to operate efficiently with large propellers and maintain thrust under load.

Thanks to the Ø37.5 × 41 mm rotor and 800KV rating, this brushless motor delivers high thrust and efficient operation in configurations with large propellers.

The motor has a peak power of up to 1724.6 W at a maximum current of up to 65.9 A. The idle current is 1.7 A, and the low internal resistance of 35 mΩ minimizes heating during long flights.

The FT drone motor for 9-10″ propellers is optimized for heavy-lift FPV platforms and long-range drones, where high thrust, smooth throttle response, minimal RPM sag, and sufficient maneuverability are crucial.

This brushless motor for long-range drones is designed for an operating voltage of 6S–8S (up to 33.6 V) and requires the use of an Electronic Speed Controller (ESC) capable of sustaining a continuous current of 70–80 A.

The Ø19 mm (4 × M3) mounting base and the high-precision 5 mm hardened shaft with an M5 nut ensure secure propeller fastening. The 250 mm long 18 AWG silicone power wires simplify soldering when building on frames with long arms.
