Pinions for a 502x

[dobber]

Hi,

Just wanted a few opinions on pinions for a 502x

Im going to be running a 6.5t losi bl motor, the track will be tight and technical with a mid length straight. (Grass track racing at SHRCCC). At the moment I have a 21 and a 22 tooth pinions but not sure if they will be suitable. Suggestions please.

Id recommend you start off on a 21T, i used to run a X12 6.5t on a 21, and on bigger tracks a 22 so youv'e got the perfect pinions really.

I run at 20T, with a 7.5T Novak motor on a fairly tight track. All the speed I need.
