Tricopter Settings & three position switches.

Does anyone have suggestions or .ini files for creating a good setup for a mini tricopter?

I am having trouble getting my setup to interact correctly with a naze 32 flight controller. My devo 10 is only giving me two working switch positions on FMOD (and MIX), whereas I need to have three in order to select between "Horizon" "Angle" and regular flight mode.

In down position and in middle position of the switch I get "Horizon", in up position I get regular (ie self level algorithm "off"). Trying to set up my channels, I see the transmitter only gives me two positions, even though I have tried both three position switches.
