I have a 28% plane that I'm looking into putting a Spektrum DX7 in to. I need to be able to put my elevator servos on some kind of Y and for personal preference, I would like to either using the Equalizer 3D or a Power Expander. I currently have your BatShare going into your Regulator, which is the one with 2 inputs and 2 outputs.

Could I use the Equalizer 3D on the elevator channel and plug the 2nd output from the regulator into it to attain redundancy?

If not, could I just plug the 2 outputs from the regulator into free servo slots on a Power Expander Sport?
