I used the support leg function on the Tamiya MFU to control my carson tipper using a seperate battery and ESC they are connected to the MFU via a 3mm headphone jack and socket with the red wire removed to stop any cross interferance between the ESC and MFU because the ESC I used has a BEC circuit and that was not needed to run the Tipper motor
I also built the trailer as a two axle one because it is a real pig to reverse because the wheel base is too short,
the red shrink wraped item is the ESC and the large coil of wire is for the the trailer lights
this shot shows the trailers connections to the tractor unit, just the black and white wires are needed to run the ESC
