Now that I'm caught up on the thread. Last wed night when I first got back I had a fun race...a heavily modified (anything metal that can be on it was, except the chassis) Slash 4x4 ended up going backwards at speed on the straight after blowing a jump. Full blast into it head on...the Slash flipped but I just didn't need to brake for the end of the straight...I just kept on driving without any issue with the car. I thought for sure something would be bad so checked it over quite well after the race, but no problems. I love this thing!
