B4.... What pinion should I use?

[BIGSCOTTD]

I've just got into the 1/10th buggy's and i have bought myself a B4 and a losi 6.5 brushless kit and a bionic lipo, what pinion should I be using? its the standard gear 81 tooth I think.

Cheers

depends on the track , something between 20 and 25
just try it out

i m running currently a 23 pinion on a mid size carpet track with a 7.5t
has big jumps and a big wallride.

a 22 should be about right

I run 23 tooth no probs motor doesnt get hot and has plenty of go go

i run a 19/81 on a very tight grass/astro track
