+1 for HobbyWing

I was burned by one of the HobbyKing "blue" color ESC's, the BEC was faulty out of the box and shot 4S directly into the Rx which killed both my Rx and my servo, I've since made sure to check the BEC voltage on every new ESC I have bought, fortunately the problem has been isolated to the HobbyKing ESC and haven't seen it happen with close to a dozen other brands of ESC's I have used over the past 10+ years... but HobbyWing has become the only brand I have grown to trust.
