It looks like an inner rotor type with a rotor inside, but in fact, this is an outer rotor type brushless motor, and the outermost case does not rotate.
The lead wire comes out from the back while being attached to the aircraft with the front case.
Since the outer rotor does not rotate in the fuselage of an airplane or glider, you do not have to worry about the wiring and other mechanical arrangements.
Ideal for F5J gliders which weighs less than 1.8kg.
