I'm trying to decide which mod motor I want. I know I want a smooth motor to help learn how to drive a 2wd. I have a 8.5 sitting around but I'm thinking that may be a little too powerful. I will run on a medium and a medium/large track w/ different layouts every other week. I believe I am in the market for a 10.5, I know some guys run a 10.5 at the larger track. So I'm looking for some options on "smooth" motors. Thanks guys
