Model was made for DEVO10 - I use full set of 12 channels. Config works good on Pixhawk and APM. I use some other set of MIX and AIL DR switches to get 6 Flight modes.
MIX0-AILDR0     FM1
MIX1-AILDR0     FM2
MIX2-AILDR0     FM3
MIX2-AILDR1     FM4
MIX1-AILDR1     FM5
MIX0-AILDR1     FM6
FM1 - In most cases is Stabilize
FM6 - RTL
That setup gives really easy changes between flight modes without too many shifting switches, and is quite straight. I didn't find anyone use setup like that before (or I didn't found it anywhere).Voice works correct for all flight modes, Last switch for Ch12 is one of unused trims and controls camera trigger.
