26t pinon with a 8.5

does that sound a little tall with the stock spur ? i would try it if i had one spare. if u guys think it will be ok will get one

feeling some speed runs.

well i have just been told to run a 19 with a 12 brushed so it sounds way to tall i would say 20 or 21

at the moment im running a 21t pinon and 8.5 brushless motor it stays cool, feel i can go taller.

might just drop the 6.5 in there ;)

With an 8.5 indoors i have been run 9.573 overall ratio on small tracks
and 9.157 on large tracks on B4

21 sounds about right
