I would think it would be 48 pitch, like most 1/10 electric vehicles.

It is metric 48 pitch and that is different than standard 48 pitch. If its not that it is metric 64 pitch but still won't mesh well with American style gears.

If it's close to a 48 pitch won't mesh up quite perfectly, it might be Tamiya's metric "0.5" mesh. The Tamiya Dark Impact/Keen Hawk/AvanteII/DF-03MS uses these gears. You can get away with using an American 48-pitch gear (like ones from Robinson and Losi for example), but it just tends to be loud.

I'm personally meshing my 0.5 spur on my DF-03MS with a 48-pitch pinion. It's a little louder then usual, but it works. My main staple in my tool box are 48 pitch, but I'm starting to like Tamiya's 0.5 scheme. The tooth are nearly identical in dimension to a 48 pitch, but the diameter of the spur comes out slightly smaller for the same tooth count 48 pitch spur.

Its 0.4.

Things would be easier if America switched to metric, You will need to buy a Tamiya pinion.

That aside, Installing anything faster then a 19 turn motor and you will start to get slower, You can't gear the car to suit, You only have 2 pinion options.
