Hi everyone, I am trying to create a flying wing with spoilers on the winglets for yaw control; everything works as it should in manual mode but my problem is that in FBW-A and STABALIZE modes the “yaw” servos on channel 4 do not move at all no matter how much I move the airframe about its’ axis. Conversely, both elevons work just fine in all three of the aforementioned flight modes.
The enclosed diagram shows how I have my system wired, the relevant parameters are included; the ones I think are most relevant are highlighted and my parameter file (burdwing.param) is attached to this post.
My guess is that with ELEVON_OUTPUT set to anything other than “0” there is some sort of bug where the yaw channel (CH4) is turned off…but I’m not sure. Any suggestions would be a great help.
The enclosed pictures show my system; the mechanical yaw winglets have not been built yet, the yaw servos are on the pink midsection; I want to get the avionics working before I tackle the airframe-architecture part.
My setup is somewhat unorthodox; I tried to follow these directions as close as possible:

…but couldn’t get my elevons to work with the recommended settings therein.
So to recap: the elevons are working and this wing flies! (see pic below) but I have no ability to yaw outside of manual mode. Again, any help would be appreciated.

Just a little above my pay grade, I have an idea but best let Tridge see this post! I wanted to say that is perhaps the clearest setup diagram I have ever seen on DIYD well done!
