My 7 yeas son often has a stock TT-02 (LaFerrari) with 2 upgrades: GPM Aluminum Front Knuckle and Bearings.
He often crashes and the front dog bones are very often coming out (and then the outer joint is ejected).
Any suggestion to prevent that?
I did not put o-ring inside. I noticed that for TT-02S there is this o-ring and it seems to be also provided with the kid.

How do you fit a Kimbrough Medium servo saver ? The top hole is not high enough and can touch the shaft.
