Pinions and Stuff
 

When i was racing yonks ago, anything higher than a 22th pinion on my motor generated a fair bit of heat. So I got conservative and stuck a 19th in the new car (and it was the only one i could find at the time) But reading about, it looks like this could be too low.. motor is a losi 6.5.. Spur is just the Cat kit standard.. any recommendations for an indoor kinda size which will get decent economy?
:thumbsup:

if its a cat sx your talking about.and indoors any were between 20 and 24

Aye sorry, it's the SX. will stick a bigger one on :D

I run a 23 tooth pinion on an 83 spur. Nice!
