Heat Issues and Cooling of Electric Motor
Hi,
I am currently using a 22cc rear-exhaust gasoline engine with a 19x6 propeller, which turns at maximum 9,000rpm at static conditions. The engine is the Moki 20 from Airworld Modellbau with details at www.airworld.de
I am going to replace this engine with the AXI5330/18 electric motor. Would anyone know which would generate more heat: the gas engine or the electric motor?
I will be using the motor on a hovering aircraft. May I know the options for cooling the electric motor?
Thanks very much

The big ones run just like the smaller ones. Heat depends on how hard you are going to work the motor. Watch your prop pitch and you should be happy with your results, motor heat will be mild. Push it with high pitch prop and she will heat up. Remember, work = heat.
