outrunner

Dog pulling outside

An outrunner is someone or something that runs ahead or beyond others.

In dogsledding, outrunners are the dogs positioned at the front outside edges of the team.

In electric motors, an outrunner is a brushless motor design where the outer casing rotates around a stationary inner core—the opposite of an inrunner—prized in drones and RC aircraft for high torque at low speeds.
