RE: Need help with "redundant" wiring system.
THe picture is from the old expander. Get the Expander Pro.
I just got the new one and it is great.
I had the old one in another plane.
I have the expander, two HD switches with dean's plugs (Smartfly sells)
And I have two 1800maH NiCad packs from Radical RC. (with dean's plugs)
THe system works great and only drops 0.1 volts at 2 amps load.
