Align under 6cell Li-Po battery, it can squeeze out more 30% torque. The new motor features power-saving for general flight and , sustained power-output for extreme 3D flight. Maintenance free, high torque, high efficiency, stable and quiet. Japanese made high-speed ball bearings, powerful magnetic outrunner rotor. These new brushless motors are designed with a new radiator system. The motors are built with an integrated cooling fan and has air ingress/egress vents, circulating cool air inside the rotor continuously. The motors efficiently lower operating temperature.
