Default Different battery voltage when using 2 batteries for retracts/receiver

I'm setting up an aircraft with mech retracts and would like to use different batteries for the receiver and retract servo. I'll be using a Y connector with the center wire removed from the plug at the receiver gear socket and a switch and battery on 1 leg and the retract servo on the other leg. Can I use a 6 volt battery for the receiver and a 4.8 battery running the servo?

Thanks,

Chris

As long as the positive terminals in each network are isolated, the answer is YES.

Thanks for the response - I'm using JR components so removing the center (positive) lead from the Y connector plug in the gear socket on the receiver will do the job as far as isolation of the positive leads is concerned?

Yes. I have a nice diagram I will try and find on how to operate the retract servo off the receiver but under an isolated power pack. Though it's pretty much as Rodney said.

"Cut the red wire" (Isn't that also what they say in the movies with the ticking bombs?)

Here's one:
