Just picked up a leftover Crossfire 800sp 2009 and also a 141" 2.25 challenger track. I am trying to figure out if I need to put a set of M8 gears in it. Anybody have some experience with the same set up?
love the set up. I have the m8 gears, shift assist, power claw, with a 48-36 progressive helix, and a set of powder pros. When I raced it in Hill X I had every hole shot, I keep up with the HCRs just fine.
