I plan on running a 2s 7.4V lipo battery on a 6V regulator in my 76" Edge540 to power the receiver and servos. Receiver will be Spektrum AR7000 and servos will be 4xHS-645 and 1xHS-5955. What battery capacity would be considered ok for this setup to get half a days flying out of the battery ? I was thinking maybe a 3300mAh might be enough but I'm just not too sure about the drain these servos would put on the battery.

Also if I'm not using a power expander/box and just running a single receiver is there any added benefit in running dual batteries on different switches, if you can do such a thing? Can someone give me some examples of a good power setup that doesn't require a power expander/box ?


Thanks, FJ
