This motor is a “classic transitional model” in the development history of racing drones, bridging the early “aerial photography era” of multi-rotors and the “racing and freestyle” of modern high-performance FPV. It provides relatively efficient and reliable power for 3-5 inch propellers (5 inches was the mainstream at the time), but the overall performance is more moderate and focused on range than extreme power.
