I have a giant scale warbird using 12 channels. The radio is a futaba 14sg with R7008SB receiver. The plane is set up with conventional wiring (no sb) and I will need two receivers. I want to use the Power System Sport in the plane, Couple of questions.

1) How do I get power from the Power System Sport to the second receiver?
2) Does the on-off switch turn the second receiver on & off?
3) The second receiver controls only lights, canopy, and other no-flight functions. Do I connect directly to the second receiver with the servo leads?

Thank You
