1.The outrunner high efficiency blushless motor was invented for T-Rex 250. Not only the superior torque and the explosive force, the 250 motor armature had a special balance adjust to improve the serious shaking problem that other tiny motors have.
2.Maintenance free, high torque, high efficiency, stable and quiet.
3.Japanese made high-speed ball bearings, powerful magnetic outrunner rotor.
