First of all, you system does not have to be very complicated. I am flying an 89" Carden Yak with an 80cc equivalent electric motor. I have two Hitec Digital servos for the Ailerons, two Hitec Digital servos for the Elevators, Hitec Digital servos for the Rudder, a Castle Creations ICE HV160 ESC for the Throttle. I use a 2cell LiFe Rx 2500mah pack for the Rx. Most Gas Engine Electronic Ignitions run on 5v or 6v. A LiFe 2cell pack is 6.6v. It is light and suitable for Rx or Ign. If you use LliPo packs, you can use a Castle Creations BEC Pro for the voltage regulation and adjust it to 5v or 6v. If you use Redundant Rx packs, you need a separate Switch Harness for each pack. I have not used the Powersafe Rx's, but I do not believe you can charge both packs from one Switch Harness.
