I am buying a used 32-3 actro motor and plan to use on a 10s lipo config. What pinion should I use to target the headspeed to 13-1400? I have setup that is now 32-4 with 22 tooth pinion. Thank you for the help.

One more thing need to help determine the pinion and that is the number of teeth on the main gear. If you are running 1400 now with the 32-4, it looks like you have somewhere around a 252T main, just working it backwards.
