Driven the XXX-nt many times and all RC's have weak points. IMO the XXX-nt's are Turn buckles and ball cup ends. The RTR has a weak exhaust couper and mount as a decent jump knocks the muffler off the coupler ending up with an annoying sound. It is fast out of the box. I would get the XXX-nt or AE RC10 GT and upgrade to Titanium turnbuckles and RPM arms for sure and upgrade the Muffler and engine.
