MMM killing motors?

[Nephre]

Anyone else that have had their motor ruined by the MMM?
I´ve got a MMM from the first batch that I thought worked fine untill today when it killed my third feigao. First it killed my 7XL in late may and I didn´t think anymore about it, Feigaos aren´t that great to be honest, they are cheap but the quality leaves more to ask. Ordered a Neu from CC, thought that I´would get myself something better and while I waited for it to show up I threw in another feigao I had laying around, an 7L. It lasted for about half an hour but I thought that since it´s not as strong as something from the XL-series, it probably died from the abuse, I don´t think the L-series are ment to be in such heavy cars as an 8th-scale buggy. After a while I got tired of waiting for the Neu (still haven´t got it) so a few days ago I got myself an 8XL that lasted for about three packs before it gave up on me in a trail of white smoke. First I thought it was the monster that died but after a quick investigation I realised that the smoke came from the 8XL.
Later this evening I checked the monster with a smaller motor, plugged it in and gave it some throttle. Everything seemed fine for about two seconds, then it started to cog and threw quite a lot of sparks and flashes at me. Holy mother of god, this can´t be right!! Well, I came to the conclusion that the monster probably killed all of my motors and I really don´t want to kill my Neu as well so I´m sending it back to CC, hopefully I´ll get a new one when the second batch is ready (when it comes to be serviceminded, CC kicks some serious butt ).
Anyone else that had similar problems? Or heard of anyone that had these problems?
