We are seeing problems with certain set ups with the MMM v2. Most (over 2400) work great with no problems. We cannot recreate these problems no matter what we do to the ESC and its BEC. The failure points are not consistent and we are trying to track down what the problem is. Whatever this is, it will be fixed. If you want to help, and have not already done so, fill out Thomas’s request for information sticky on the forum.
A failed MMM will be repaired/replaced at no charge within one year from date of purchase. If there is any work on the circuit board or other obvious modifications, or there is crash damage, the ESC is out of warranty and will cost $70.00 for out of warranty replacement.

Thanks Bernie.
Very clear.
Glad to hear you guys are on this.
The only thing I am having a problem understanding is the low percentage failure rates CC is currently reporting. I personally know of 4 MMM V2s in my local area. All 4 have failed. I know this is a very low sample size, but if all 4 of us got one of the 1.5% failure rate I am going to go and buy a lottery ticket right now. The odds on that are astronomical. (Edit: did the math... odds are over 19 million to 1 of this happeneing at 1.5% failure rate. I'm not that lucky, or unlucky)All 4 are running different setups in differnt types of vehicles. The setups on the setup data collection thread are all very different accross the board. The only common thing I see in all of the reports is that the failures were using the on board BEC to power the Rx and servos.
I just got a 2nd MMM V2 and am planning to run this one with an external BEC. So far in that data collection thread not a single faiure has been reported while using external BEC or Rx pack.
Do you know of any failures reported from people runnig the MMM V2 with an External BEC ort Rx pack and the red wire pulled on the rx wire? Id be wiling to run this way if it will insure reliability.
