The DX7 manual is virtually identical to the JR XP7202 which by the way
has the synthesizer programmed via the menu, not switches like on the
modules.
I put togther a 6 servo program on the 7202 for sailplanes. This gives
you the following mixes/presets
Aileron to Rudder
Aileron to Flap Coupling
Elevator to Camber, full span
Two Camber Presets (Launch and Reflex if you have a TD ship)
With a 7 channel RX, you can do the following.
Channels on a 7 channel JR RX
Thro - Left Flap
Aile - Right Aileron
Elev - Elevator
Rudd - Rudder
Aux1 - Left Aileron
Aux2 - Right Flap
Setup
Wing Type - Flaperons, V-tail as required
Switches, Aux2 [Inhibit], Aux2 Trim [Inhibit]
Flap [System], Flap Trim [Inhibit]
Left 3-position switch will be down for launch, up for reflex
Programmable Mixers
Aile - Rudder +10, +10 (Only one aileron to rudder mix is available,
but you could turn it off)
Elev-Flap Mix +20, +20 (This is elevator to camber for the ailerons)
Mix1 Elev - Throttle, +20 +20 (This is for elevator to camber for
the flaps)
Mix2 Aileron - Aux2 +50, +50 (Part of Aileron to Flap mix)
Mix3 Aileron - Thro +25, +25 (Part of Aileron to Flap mix)
Note that the numbers are different for aileron to aux2 and aileron to
throttle because the Aileron to throttle changes both flaps so Mix2 must
negate that. That is why the value of Mix2 is double Mix3
Mix4 Flap - Throttle +70, +70 (This is lap system preset mix into the
flaps, Use Flap System meny for preset settings for the ailerons)
Mix5 Thro - Elevator 0, -30, 100 Offset (This is your elevator
compensation for landing)
Mix 6 Thro - Aux2 -100, -100 (This is to get second flap mixed in.
Note -100 values)
Flap System, Use Up Flap value for Reflex and Down Flap value for
Launch. You can also use elevator presets in there if you need a little
elevator offset for launch or reflex. (Or you can use reflex and camber
if you don't need launch like on the slope)
What is missing is from the program that you normally have in a
sailplane program:
Multiple aileron to rudder mix settings.
Change differential in launch or other flight modes
Changing aileron position when landing for crow/butterfly
You could probably trade off crow mixing of ailerons with aileron to
flap mixing if you wanted.

Jim, I'm reading the Spektrum manual and I don't see any wing type for 4-servo
wings with separate flaps and ailerons. I'm probably missing some obvious
work-around, but on first glance it doesn't look as if they gave the sailplane
boys much of a thought when they designed the programming.

I am all over this, full range spread spectrum just announced
today... the day is getting close when we will never bother with
frequency pins again. ;-)
