Quark Woes --- Need help please

[zeropointbug]

He is using the Quark.

When mine was doing this, after a few minutes of running, the truck would just stop, alot of the time when I would go reverse/forward. But I don't remember if I lost steering or not, but I had to switch off the controller, then on again. It was not thermalling, the case was quite cool. This was actually after I saw the capacitor electrolyte on the outside of the controller (collected dust). So I guess one cap was still working, it was weird.
