FWIW, all of my jets have a dual battery system. My F15 has a separate battery allocated to the elevator servos, and just as well, because it seems to cop a hammering each flight judging by the readout from my on board volt logger. All of my new jets have incorporated a powerbox, but I have noticed that power consumption from the batteries seems to be greater than I expected. I guess the powerbox itself consumes a reasonable amount of power to perform its signal amplification and other functions. Anyone else noticed this? David, what have you seen on your systems (I am only using nicads at the moment with mine.)
