Team checkpoint motors
 

Can someone tell me the break down as to how many runs you can get out of each wind of these motors with the stock timing settings before it needs to be cut or new brushes need to be put in them? 6,7,8,9,ect. I have read that some of the milder mods get up to 60 or so runs, but have not seen anything about the hotter mods. Is there any maintance required to keep these motors running strong between cuts and brush replacement?

You should check out the Checkpoint thread. http://www.rctech.net/forum/showthre...65#post1946265
This is discussed quite a few times in there.
