If it went up in flames -- it wasn't a BEC failure. Most likely it was over current -- setup incorrect, and possibly demagged the motor. Every major failure like this that we have seen have been setup problems where the current rises from a damaged motor so quickly that the over-temp doesn't have a chance to kick in.

Mine burned. I put the Max back in and it is fine. Same motor, same connectors. The only difference is one is a MMM and one is a MM...and one works and one doesn't.

In that case, it could just have been a bad FET, it could have been a bad solder joint on a FET, or a solder joint could have cracked on a FET.

Send it in, we'll fix it up. :)
