I don’t know what the outlaw is, but you need to find a little box that the servos plug into. Follow the wires, it could be protected inside a removable cover of some sort. Do you have a manual for it?
Welcome to RCT. There are lots of different RC's with the name Outlaw. There is the FTX, Kyosho has an Outlaw Rampage, Tyco had an Outlaw years ago. So let us know what you got and we can point you in the right direction.
