Im a bit confused.
Are you racing your XSC right out of the box? because you are really stressing the break in break in. I have about 3 tanks on mine and I havnt had a single part break.
I unboxed it, spend several days going over every inch of it. Locktite on everything that needed it. Pulled all the steering links and checked the measurements. Clocked all the ball links to get the slop out of them, just basic prep.
My truck is 100% stock, bearings are all tight, servos are holding, (new ones already ordered) heck im even running the stock failsafe till my killer bee arrives.
So either its Operator error or you got that one in a millon lemon.
All the flaming you are doing to the XSC is a bit over the top.
I have had a few ppl contact me questioning the quality.
At the end of the day its an entry level (price) kit.
Its intended to be upgraded, your acting like all of them are crap.
Please stop blaming the XSC.
