As a minimum:
Two 2200Mah batteries reciever, and one 1200 Mah ignition. Each through a separate switch, as you stated.
NiCads are fine, but a little heavy - 4 cells direct or 5 cells with a regulator.

Agreed with you up to this point. WIth 5-cell packs, either NiMH or Nicad it is NOT necessary to use a regulator. You can plug these packs directly into the RX.
Lithium packs will require the use of a regulator to bring the RX input voltage down to 6 volts or less.
I run 2 5-cell 2700 mAh NiMH packs on my 33% Edge throught 2 switches plugged directly into the RX. I also use a 2700 pack on ignition, also 5 cells (DA ignition). No regulators anywhere.
