B4 Gearing

[strobe]

What tooth pinion would you use with a Checkpoint 11x2 motor and VTech 4200 cells on Astro or a Grass track. Using a Standard size spur gear which comes with the Factory team kit.

Any one got a good setup for Coventry astro track and Kiddy's multi-surface track for a B4 FT.

i think a good staring point would be a 22 or 23 tooth pinion
