trf 502x question
 

ive recently bought a 502x and was wondering if there is a recommended pinion size to use?

ill be running a speedpassion reventon pro and speed passion 5.5 motor.

the car is totaly box standard so also wondered if there are any recommended upgrades for the car too

thanks

recommended ugrades :

- DIFF BALLS DIFF BALLS DIFF BALLS
- change the steering geometry : the LM mod or the hopup angled steering I prefer the latter
- lower the inner ballstuds if you're running on high grip tracks : the Rudebits set or the Tamiya hopup. both do the job

Those are the essentials.

I was running mine on a med size astro track with a 6.5T and a 19T pinion..so I would go 17-19T depending on your tracks size..
Also get the upgrade pack if you can, it changes the car greatly.

Thanks for the replies guys. Ill see if I can find the upgrade kit too
