Wltoys 12428 differential spacer

thingiverse

I had problem on my Wltoys 12428, that front differential was way too tight, it was almost not working. Car was understeering a lot. Therefore I did spacer to make it work better. In my case 0.3mm was the best, but you can download variable thickness 0.15/0.20/0.30/0.45/0.60 Use as thin spacer as possible, if you choose too thick than there is a risc that tooths will slip.
