I need some help with gearing on my Tamiya F103. I have searched but can't seem to find my answer. I have a Novak GTB2 ESC and Novak SS 17.5 I plan to run on 2S. What Kimbough Gears will fit on the F103. Should I use 48 pitch or 64 and which Spur and Pinion should I use for best ratio for parkinglot running?
