looking for help cat 930 build

[crusher]

Hi, I have been lurking around this forum for some time, I have started a scratch build of a cat excavator, it is not true scale but something close to 10%. I am looking for help as to the electrics for the build. I am planning on electric motors for the tracks and swing with hydraulics for the rest.
When it comes to this part of the build I am completely in the dark. I have a Futaba 9 channel radio and pcm receiver from my last hobby. I see posts talking about escs, bec etc. all foreign to me. Does anyone know of a schematic or a good place to get the info I need?
Thanks for any help you can offer.
Terry.
