I have broke several things on my Maxx, spur gears, driveshafts, motor mounts, ripped tires off rims, skidplates, body, bulkheads, A-arms, fuel tank and lots of other stuff I can't remember. I have a big sack that I keep all the broken parts in. The worst looking incident had to be breaking the bulkheads. Head on into a curb at almost full speed.....
