Inrunners: Magnets on the inside mounted directly to the shaft; winding coils and stator are mounted to the inside of the can and surround the magnets. Can is stationary.

Outrunners: Winding coils and stator are inside fixed to the bearing tube; magnets are placed in a rotating can that spins around the windings.

Outrunners tend to have lower Kv and higher Kt values for a given motor size and are more commonly used for directly driving props, whereas inrunners are usually used with gearboxes or in high-speed applications running a small, direct-drive prop.
