Ultrafly C/13 Series brushless, sensorless motors are not only the industry's first to feature an internal cooling fan that doesn't require an external power source — they're also the lightest 200W motor ever made! Designed for helicopters and planes that demand superior power-to-weight ratio, the self-cooled C/13 transfers 200 watts of power, yet weighs only 1.6 oz (45g). Even in installations where there's little air movement, such as scale planes with enclosed cowls, the unique fan design still keeps the motor core to just 90∞ at a constant 180 watts of power. High-quality construction and CNC-machined fan blades that are integrated into the head of the motor enable C/13 motors to operate in a high rpm range without significant vibration. They can even handle up to a 6-cell LiPo pack with ease!

C/13 motors are the perfect choice any time you need a lot of power from a small package.
