Pinion/Spur advice?
 

Using a bog stock B4RS currently with the Brushed motor/ESC.

Bought from here a 13.5 turn brushless system for it. Tend to race mostly indoors on carpet at a smallish track, any ideas of pinion for the new brushless motor that will be a good start point. Want to keep costs down so use the standard spur that's fittted, but just get a pinion if possible.

Just a good base to work from that hopefully won't send any temps through the roof for motor/esc/battery!

id try about a 28 and see how you go from there mate. Are you using decent lipos?

Cool, I'll try that....using GP 28C 2S 5000mah hard case packs.....Seem pretty good, what do you think?

should be alright mate. Just try it and see. Have a temp gun handy if poss
