I have just started running a 416X I bought used with the thin Exotek chassis in a Spec GT class on asphalt. Class limit is 21.5 motor, blinky ESC and no less than 5.5 FDR. I'm at 5.56. I'm running a Novak Ballistic with maximum motor timing and a MMP ESC with a Venom 5000 25C Lipo.
Car handles wonderfully but I'm getting my butt kicked on speed. The car has a Spec R gear transmission in the rear.
Can I still use the 2.055 internal ratio for calculating FDR with the Spec R setup?
