RE: 6v or 4.8v reciever battery?
LargeScale88,
Something else to think about would be do you plan on going to 2.4 in the future? If so, 6 volts is the way to go since there are issues with brown outs and low voltage running 2.4. I have been on 2.4 for over a year and run 6 volts on all my onboard equipment.
