how to setup a hyrauilic excavator on a 6channel?

[cosworth34677]

ya the problem is my turn table is runnig off a big 1/4 sclae servo and i will only run on 6v.
i really thinking of gutting the 1/4 scale servo and running it off a esc. but its a bruder convert and with the pump valves batttery bec and rx there is not much room.

wonder if there is a way to run the servo off 6v and the others off the safer 4v ?

this will work scroll down on the link to view the wiring setup, just get 3 of them and put them between the servos and receiver.
