This is a place to discuss support for dual-motor tailsitters with ArduPilot. This is for any fixed-wing airframe which sits on its tail to startup, and has two forward motors for thrust. The motors use differential thrust for roll when hovering, and elevons for pitch and yaw.
Support for this type of airframe is in master now, but has only been tested in a simulator. We're now waiting on the first real aircraft flight tests. Mark Whitehorn may well get there first, as he already has one flying with PX4 and has indicated he is interested in trying it with ArduPilot.
The only real-world tailsitter testing with ArduPilot so far has been with a 3D AddictionX (see http://discuss.ardupilot.org/t/ardupilot-flying-3d-aircraft-including-hovering/14837/14 for details and flight videos). That went very well, but didn't test dual-motor support.
One possible issue is yaw torque caused by differential thrust. I think the addition of a feed-forward parameter between differential thrust and body roll would reduce that to a manageable level.
Please share your designs for dual-motor tailsitters here, and any flight videos (successful or not!)
