Does anyone know the internal gear ratio of the XX4 and also a site that lists gear ratios for the car.

Thanks.

Cheers mate i found that one last night but i'm not sure if the internal ratio is correct on it?!?

2.3:1 is my understanding

Cheers Phil, this seems to be the correct ratio your the second person to mention it to me.

Any rough guides for gearing an LRP 5.5 on a purple 84? spur?

[bigred5765]

depends on the track but start at 14-15 tooth pinion

Just follow the recommended gear ratios that came with the motor and you will be fine.
