The F40 Pro 2305 2400KV motor has been designed and built specifically for racing. It features a steel shaft and a unique rigid design to prevent shaft bending and rotor deformations during crashes. At the same time, the motor is very powerful and reacts quickly.
T-Motor motors have long been among the best and most powerful motors for FPV racing drones on the market.
