Also my friend bought a used hyper 10sc and it came with this little cable that I can't identify. It has a female plug that looks like the esc or servo would plug into then goes into a circuit board and back out to a male plug that looks like it would plug into the receiver. The board has a tiny button on it. They guy he got the truck from said he didn't even know what it was for. Could it be just a fancy on/off switch?
