I have the novak and its pretty nice but its large size makes life a pain when mounting. I have actually had BEC problems sometimes when I got my Axial really wedged in tight, funny I go to a sidewinder micro and the problems seemed to go away [&:]. The FX-R is extremely popular in crawling circles for comps.... I think the Rooster should be fine for your SCX10. Just do remember it can only handle 2S lipos max which is a bummer if you wanted more power. The Novak 55T is nice and torquey yet smooth. I have run a zillion battery packs through it and not even touched it to check the brushes....
