This is a typical servo/Rx./switch/battery set up used in large warbirds. This set-up provides redundancy on switches and batteries. Also you can fly with 1 aileron or even 1 elevator half and save the bird. I recommend using either a voltage monitor that is visible from the outside of the aircraft or on/off switches with charge jacks built in to check voltage before each flight. I put the volt watch in place of the instrument panel and it is very easy to read in this location through the canopy. Turn on 1 switch and read the voltage, now turn that one off and turn on the second and read it. If both are good, turn them both on for the flight. I normally only use 4.8 volt packs,1650ma in pairs. You can mix MA capacity packs like one 1200ma pack and a 700ma pack. Just dont mix VOLTAGES. You shouldnt mix a 6 volt and a 4.8 pack. Down here we have very high humidity and have seen some corrosion problems in connectors after years of exposure. I hard solder all my Y connections.
