CC BEC ,design flaw.

Patrick,I threw 1 away but I'm actually pretty close to you so if you want to test the other 1 to see why it failed your more then welcome to it.I need to come in to your shop once you get some MM in anyways.But what I'd like to know is if all these can fail like this,and you know how to fix it,why not do it?BTW 1 of them had only been used with 4s and the other all 4s except 3 times with 6s and a couple with 5s.The 1 I threw away had some slight wire fraying on the receiver wire at the board.Which I couldn't see until I unwrapped it.But it didn't appear like it had been able to short.
