Spur and pinion suggestions... -

E-Revo transmission with V2 RCM hybrid diffs (with buggy diff) and 2200 kv CC motor on 6s. Can anyone suggest a good starting point for a pinion and spur?
This is for bashing so a balance between run time, temps and speed would be good.
using brians calc not sure if i'm completely correct on this
i just put in buggy diffs and your e revo trans
your motor is spinning at nearly 50k too on 6s
and gear lower may be an issue unless you mod a spur or are using mod.8 ie 32p
