The Sub250 M2 1002 14000Kv is a smaller motor designed for 1.6-2" propellers in combination with a 2S battery. It will serve especially well on small Toothpick drones. Even with the small size, the motor uses strong N52H magnets as well as ball bearings. The motor is equipped with 40mm long cables that are terminated with a connector for easy connection to the AIO board. A 1.5mm shaft is used.
