Horizon Hobby X-Vert VTOL for Devo 7E

While I've had my Devo 7E for a couple of years and love it, I STILL can't seem to figure out how to properly set up a new model config.

Does anyone have a good working config for this craft. My 7E is modded with dual 3-poaition switches. Would like for SW B to be the modes switch and HOLD to be arm/disarm.

I'm including a pic of the manual that explains the channel assignment requirements
