Default Wiring help for separate retract batt for JR S791

Am using a JR S791 retract servo that only runs on 4.8V.
Am using a 6V pack for the RX supply on an AR7000 to supply control surface servos.
Am using a separate 4.8V pack run thru a switch to supply the retract servo so in case of a retract issue RX pack won't draw down or go into brownout.
2 QUESTIONS.

Will running 6V to the RX cause any issues as far as the signal to the servo?

Is my wiring schematic correct for hooking this up?

You will also need to connect the black wire to the RX. Without it, there will not be a complete circuit for the pulse. As long as the red is separate, the batteries will be isolated.

Thanks Chuck.
Thanks Alan. Wish I'd have thought of using a Y connector before I cut up my switch lead to solder the RX input to it..good schematic.
