Still, waiting for the local shop to get my Kimbrough spur gear in for my F103rs. I hope they get it in today, so I finally have it ready for the track.
Whats a good pinion to run with a 75 tooth spur. I'll be using a P2K w/RC1700 cells for a 5 minute race with foam tires.
Also, should I go up or down on the pinion if I switch to the rubber tires instead of the foams.
