This outrunner motor is mainly designed for micro size helicopters, such as Walkera V120D01, D02, D03, D05 4G6, 4G3, 4#6, etc. with 14t to 16t pinion. For maximum life, please ensure that the bearings are maintained properly; put a small drop of bearing oil on each bearing every 5 flights. And please make sure that a sufficient gap is left between the pinion and main gear during motor installation to avoid binding and causing over load to the motor.
