Ouch!
Broke my chassis Saturday.
Cant recall any hits hard enough that I thought should have done that.
broke at the front left rear hinge pin mount
Just enough to make it sit wonky and handle like shit.
$$$$

Car felt super dialed for 1st 3 practice days at Tamiya USA track, had some bumps during those days also.
4th day, handling went in the crapper and couldn't figure what wasn't just right.
went thru setup process, tweek, droop, ride height, camber and just wouldn't hold front droop then noticed (well, someone else) slight irregularity at that hinge pin mount, the separate type on this 419x.

bummed but at least found it
