just curious as to what type of brushless systems people are running. I was told at one of the shops that the 6.5 novak system was the most popular. i wanna buy one but do i buy the 6.5 or the 3.5 or what? I wanna be in the same boat as everyone else so thats why i ask. i plan on running it in my touring car. and can i run a momba or not, because its not roar approved. also as far as batteries go are the mod\brushless guys running lipos or nimh?
