3-shoe setup on both my Lightning Pro and my son's ofna buggy. in both cases, the shoes point clockwise. thinking about it, the engine would spin counter clockwise (if you're looking at drive shaft). i guess flipping the shoes to point the otherway (counterclockwise, with the rotation of the engine) would produce the bite you're talkign about?
i had a 1/10 scale clutch apart once, but I can't remember what it looks like in there.
