Just got my bone stock ax10 back, here's what I have & have done so far:

Novak 55
weight in wheels: front 6oz, rear 4oz
moved lower links in, moved shocks out
mirrored transmission

next to do:
bent rear links
extand upper arms (read it helped with articulation)
shocks - wanting to run internal springs, but curious what this will do for me? Also going to flip em upside down
move batteries to front axle

Any other suggestions?
