MMM took out rx and servos

[secondgear]

Ran 6S for the first time on my E-Revo. NeuCastle 2200kv motor 18/68.

Ran really nice and made nice power, but I ran into problems.

5 minutes into the run, the truck stopped responding.
Disconnected the battery and started looking around for what failed.
Found that the BEC on the MMM had failed. The RX was burnt out from over voltage. Both servos had failed.

The only thing I can see that caused this is the BEC failing and sending pack voltage through the rx to the sevos. Assuming the rx took the voltage, the servos failed and drew more current which took out the rx.

Anyways, this MMM was purchased back in 2008.
Is Castle replacing these older units? I assume that this is V1 or V2
