This is a vectored thrust flying wing. It is based on the ExtraSpecial, but the graphics have not been updated to reflect the changed airframe (I don't have the tools or skills to do that unfortunately). I'm using this to develop support for vectored thrust wings for the ArduPilot open source autopilot.
The control inputs are setup for ArduPilot. Elevons on channels 1 and 2, motor tilt on channels 3 and 4 and motor thrust on channels 5 and 6.
The airframe this is designed to match is this one:
it is has a very interesting control system that allows a dual-motor flying wing to hover well, but also land flat.
If anyone has the time and skills to help me get the graphics right (even approximately) that would be appreciated.
