Does it go from the Tx to the Rx, then from the Rx via the same wire that it receives power from to the Esc??
Right now I have the roller and motor/esc. Can I use my Spektrum dx3s with the Rx from my nitro buggy? Then be good to go? It just seems that there is a missing link, maybe because I am used to the double servo's. If someone has a detailed schematic that would be awesome.
You've got it right. There are three wires connecting the ESC to the receiver. The "+" and "-" power the receiver and other things that are plugged into the receiver (servo, transponder). The third wire provides the communication from the transmitter through the receiver to the ESC and to the motor.
