In one more attempt to test the abilities and push the limits of Bill's UAV DevBoard, I removed the winglets from my tailless design so now there are no horizontal or vertical stabilizers.
The video is in three segments; the first showing manual flight with stabilization disengaged. You can see the difficulty I had flying a tight figure eight pattern. The next segment displays flight in stabilized mode which is noticeably smoother and the last shows turns at three waypoints.
Even without the vertical stabilization, there is some yaw stability due to the wing sweep but it is obvious and pretty impressive that the DevBoard firmware can still handle a plane with marginal roll, pitch and yaw stability. Enjoy the cheesy music----- Note: cheesy music replaced with cool music.
