    I use the stock 70 tooth spur and 20 clutch bell and like the performance.

    From the manual:

    Nitro Sport comes with a 70-tooth spur gear and a 20-tooth pinion (clutch bell) gear. This combination will provide the best overall acceleration and top speed. If you want more acceleration and less top speed, then use a smaller clutch bell gear (fewer teeth). For more top speed, use a larger clutch bell gear.

    Check out page 8 in the manual for a helpful gearing chart
