Class is 17.5 blinky, Rubber tires on Medium bite carpet. I'm running 64p gears with a 96 spur.
You should include track size. Brand of car would also help if you are looking for someone to tell you which pinion to use with your 96 spur, instead of just the FDR. They have different internal ratios.
4.0 FDR is a reasonable starting point for a medium sized track. Lower for larger tracks.
Can timing...Crank it up, but check temps often, use a fan and make sure your drivetrain is as free as it can be.
