Hey Guys

I have a Slash 4x4 i bought used and it has stock VXL Brushless set up

Using a 3S 4000 pack 20C and after a few stop and go runs then full throttle it seems to go into safe mode

The LED Goes from Green then Stays Red

Then the initial full throttle punch is no longer there

I have to unplug and replug the battery to reset the ESC

Button is NOT Stuck

Any ideas how to fix it so it stays green?

I have 3 new batteries and it does it on all 3 batteries

Thanks
Mike
