at this point his design is fine or it wouldnt last multiple runs before failure. there are certain components - fets and becs that arent living up to the ratings that castle thinks they are buying- read made in china.
this is classic - vendor supplies samples to win the bid. they are tested and no issues. then sends 2500 of them that have 10% yield failure.

I don't buy ANY materials out of China, and most of my parts are direct from the manufacturer.
So no, this isn't the case.
We are investigating right now -- but the failure rates are not all that high (regardless of the noise on the boards...)
We have also seen that most people don't have a problem, and then others toast 3, 4 or 5 controllers in a row. We are trying to figure out WHY some people toast many controllers, and others are just fine. It might be broken servos (we have seen broken digital servos damage switching BECs) or it could be bad motors, we just aren't sure yet.
