Problem with mgm 16018 under acceleration

[munarin]

Hi,

Just wondering if anyone has a problem with their mgm esc under acceleration?

After reading much on this forum the finally setup I decided on was 2 venom 5000mah 2s lipos in series, so 4s into an mgm16018 speedy into an 8xl motor. The setup is perfect, no temps too hot but after I have run the thing for 10 mins with no problem, under acceleration (ie. fast squeezing of the throttle) the savage launches and as soon as it looks like it is about to really get going in dies. If I wait a sec, (trigger back to neutral) the motor is away again. I pulled the batteries and my voltmeter was indicating 7.234 volts per pack. My understanding from what I can read is that the mgm cuts power at 3.3 volts per cell so I am short of that as I have the setting on the controller to cut motor power once at the lowest voltage.

I have tried to find any other posts in the forum searches but have not turned up much that is helpful.

Any help would be great.

Thanks
