Need help with my pinion and spur gears

[Matt King]

I've got a 1/8 buggy
A 19 tooth pinion and a 70t tooth spur, will they go good together or should I get different ones, the pinion gear is from my 1/10 buggy tho so I'm not totally sure.
Help!!

More than likely no... we also need kv of motor and how many cells or voltage of fully charged battery ...the pitch of a 1/10 scale and 1/8 scale are different....
