At the track I went to, they had a set of doubles in front of a table top. Most people were clearing the doubles and landing on the backside of the table top. Since it was my first time out, I nailed the jump going waaaaay too fast. I cleared the backside of the table top by a good 3 ft

and got a TON of air. Anyway, the chassis came down flat, and nothing broken.
I did enough cartwheels and crooked landings that my Pro-Line V2 (front) and V3 (rear) wheels are now crooked (I did check, and it's the wheels, not the tires!), and I didn't break anything. Only thing that happened to me is that one of the screws on the wing stand offs fell out (did not loctite them, and I was using the aluminum stand offs).
I'm not a good driver at all, and really punished the car, but man, I didn't break that much stuff in one outing!
I did a few nosedives after jumps, which resulted in some nasty end-over-end cartwheels. Did you do some of those after really BIG jumps? Those batteries look like they've seen some serious front-to-back impacts, which is what I'd expect to see from a car that goes head-on at full speed into a wall or curb, or even head-first (or tail-first) after a landing on a big jump. An impact like that could break the chassis braces too. While the car is very robust, if I ran it at 30MPH into a curb, I certainly wouldn't expect it to just bounce off without any damage!
Just fix the stuff and go back out there! Gotta get back up on the horse, so to speak.
