MGM fried immediately

Generally speaking, the MGMs are like any other piece of electronic hardware. If it starts up on the first try and runs as it should, odds are that you won't have any trouble with it. I have two 22418s. The first fried on the first day that I had it, so I bought another to run while the first was on its trip around the world. I took around two months to get it back. The second that I bought hasn't given me any trouble. I have since gotten the first one back and it hasn't given me any trouble either. With the switching bec, I liberally swap among 4S, 5S and 6S lipo with my 1515 2.5d. I've also recently been running the Compros with the Align 600XL (1650kv) motor and I think I like it better than the Neu in terms of the way it runs. Heat issues are still undetermined, since I haven't had the time to really give it a run for an extended length of time.
