I believe it needs to see netural when switched on or it won't work. Its a saftey feature. My Heli esc's all work like that. As with all electroincs I always power down and back up when something strange happens.

Sounds like you pack can't handle the load at that point and the draw drops it below the LVC. Search the forums here there are others with mgm lvc issues.

I realy don't think that my pack can't handle the power. I've a brushless system who's make to go in a heavy 13lbs+ monster truck, and it's in a 8lbs buggy.
I think that's this *(&%%$%(? MGM LVC who's the main trouble. And i've the latest 3.21 version:whistle:

MMM or CC HV110 with pistix is near to be my next purchase.:yes:

It does seem pretty unlikely that your pack would not be able to handle the power but it is not impossible. I just sent in my 2s trakpower 4900's for replacement because neither were able to hold voltage under load like they should. There are going to be defective cells from time to time no matter where they came from.

But an easy way to check should be to put your controller in race mode and run as you normally do until you either exceed your general runtime @ 3500mAh or the first signs of decreased performance. This should be a good indication of what is causing the problem.

Sadly my 16018 that had been running good on the old 3.12 firmware went up in smoke during my first try at running 6s on it and is taking a leisurely trip to it's homeland. I wonder if it will return before I receive my mamba monster that was ordered during the 2nd presale...

I hope you get your issues worked out soon.
