Does anyone know of a reset for the 4pk? I'm having major issues that I thought were, until recently, my ESC, but now it happened again in a DIFFERENT CAR. The radio is the only common link. Someone told me there is some sort of master reset that can wipe out EVERYTHING and potentially be a fix. I've already jotted down my important settings for my 4 vehicles stored in the transmitter. If anyone knows anything about this, please help. Thanks.
