Oh, I was constantly having issues with it. Not all were major though but after 11 months even the small things get to you. I don't think I ever had one run without issues. I was one of the few agreeing with you on the Traxxas' forum
I got a 6T and I have finally broken two things; the rear shock tower which slightly cracked from repeated landings up-side-down when doing back flips and a lower front a-arm. Missed a landing and the jump had a curb which the wheel got stuck on while the rest of the truck was in the air so the a-arm and wheel took the hit.
Wing and body is starting to fall apart but those break on whatever car you'll get. At least if you drive them like I do
