I have a local racer who's been using MMM for some time now. It seems like those he got always gave him problems. I read his posting and he got flamed by the Chief Engineer of CC. Just to let everyone see and decide for themselves.

Alan,
Sorry it has taken a little while to get back to you, we have been a bit short staffed the past week. It may have simply been a defect in the controller which does happen from time to time, no product is infallible and we'll be the first to admit that. Our controller does have very low internal resistance, which allows the motor to pull more curent, so it may be pushing the batteries harder; which would explain why it failed on ours but not the lower rated controller because it's not allowing the motor to reach its full potential, so it isn't pushing the batteries as hard. We'll get the controller replaced and get you back up and running. Please let me know if you have any other questions or concerns.

Your post was a troll post. "Trolling" is when you post something just to be obnoxious, and not to add any good content to a thread.
If you have had issues with the MMM V3, then you should post here about your problems, and maybe we could help you out. It doesn't do anybody anything useful to just post obnoxious inflammatory posts. ESPECIALLY when you come into my forums and start flaming my products.
