I am thinking about planning for using APM in a big flying wing that has split elevons and rudder. The control surfaces at the wing tips are elevons, and the inner control surfaces are elevators only. This alone takes up three servo channels, plus one for the rudder, and one for the throttle. However it doesn't seem like APM supports rudder at the same time as elevons, not to mention elevons + elevators... The wiki says:
Yaw/Rudder channel only used when ailerons are configured for Roll Control
So, does this mean I couldn't use a rudder with elevons? Also, is the combination of elevons plus elevators out?
Differential ailerons were added recently and apparently flaps are coming too. For a flying wing with split elevons, flaps could be done with combined differential ailerons and elevators that move in opposite directions. I suppose this is called "crow"?
If support for these kinds of control surface combinations is being or will be developed, I suppose the amount of servo outputs will be 1 channel for elevator, 2 for elevons, 1 for rudder, 1 for throttle.
The plane in question would be the Hercules Gentle Giant. For those building it with two motors... and since I'm already in wish-list mode... how about independent throttle channels for increased yaw authority? :-)
Here's a clip that shows the split elevons. Also, a massive payload on that thing.

I know this thread is old, but I have the Hercules Gentle Giant and am in the process of trying to map the split elevons with an APM 2.0. I was wondering if you made any progress in figuring out how this would work.
