Pinion Calculation.

[Markoxx4]

Hi Guys,
can anyone tell me how you calculate what pinion to use.
i have a losi xx4 and a losi xxx 2wd
in the xx4 i have a 6.5 brushless lrp system on a 88 spur gear
and in the xxx i have a 19t with a standard spur(not sure how many teeth) but am going to change the motor in that so need to know how to calculate what pinion.
thanks for any help
Mark
