Since we are discussing motor designs I have a few questions...

I had 2 of the old feigao xl can motors. 2 pole and cheap!!! I had a 14xl that I ran on 8s, and a 7xl that I ran on 4s. In the same weight vehicle with the same gearing (thus load) the 14xl ran cooler.

I am guessing the motors use the same materials and construction techniques. Are lower kv motors more effecient just due to design? Higher turn motors use thinner wire and more of it, is that inherently more effecient?

Just wondering. The 7xl was very gearing sensitive to keep temps down to "reasonable" levels. while the 14xl did not seem to mind. Amp draw must have some bearing, as less amps means less heat.
