Please, tell me about this hubmotor. It looks very unique and has the potential to save a lot of weight and space.

i'm bad at explaining things so read this instructable about hubmotors http://www.instructables.com/id/Make...b-Motor/#intro
i actually did not make the hubmotor, i bought it from the guy who wrote the instructable on it. i really don't have the patience to wind motors...

Very cool, thanks. It seems like a simple concept. I even got to know an LRK winding pretty well when rewinding an ebay motor for a 150g about 6 years go. If it runs astray, gobrushless.com has lots of supplies to make your own (or repair).

i was going to make the hubmotor myself but it was cheaper and easier for me to buy it from him when he was clearing out old projects.
