Re: Hovercraft

You're right, max output of a CIM is somewhere in the 300 W range. For these back of the envelope calcs, I was assuming 100% efficiency in the CIM motor (and in the gearbox, and in the fan). 12V * 40A = 480W is the maximum input to the motor. It's not 100% efficient. But, you could always use two of them put together if you wanted to...

Also, can you provide some documentation about motor outputs? I though CIMs output about 300 watts.
