I also was using a Monster V2 with the Castle BEC. It was running great for 7 min in my buggy then it stopped working. It smoked my receiver and the Castle BEC was outputting 15 volts and burnt my receiver. I did checked the new receiver with a seperate 6v batts and everything seems fine. Then I hooked up the Monster BEC to the receiver and then the smoke came out of the Monster ESC. This sucks but they are at least replacing it or repairing the ESC when we send it in. Goodluck to all that runs the Monster Max, hopefully some are actually having fun instead of worrying about having a dead ESC.
