Gear pitches for caster buggy
 

Does anyone know what the gear pitch is for the caster ex1.5 buggy?

I'm looking to gear down but not sure whether to get 32dp or 48dp.

And would someone be able to explain mod1 mod 1.5.

Also, if you know the stock gearing for the buggy that would also be great as im looking to gear down to lower motor temps :)

Cheers
