RE: Brushed Electric Motor Break-In Guide (Not Just For Heli's)
yeah, no prob =)
I do believe that carbon gives the better performance and the silver would last longer, although I am not really sure. I'm also not really sure if there would be anything special you would have to do, but I would say just break them in as normal =)
You could try a set of each and see how they perform and see which ones you like the best. The car guys might know more about what kind of brushes are good for which application. They would deal more with motors with interchangable brushes than us heli guys =)
