I've seen plenty of 3 and 4 rotor multicopters, but not many twins. Is the yaw controlled by rotating the motors fore and aft? Seems far more complex than tri or quad copters.
Yes, the motors tilt on this copter at 60 degrees, the original design called for 45 degrees. I have not noticed much difference between the two however at 60 degrees, there seems to be a little more forward speed. This may be due to my flying skills have improved over time.
Here are a few pictures of another one of my designs I have named Sweptback because of the configuration of the forward arms. The arms are swept to remove the props from the camera's view and because of this, other modifications had to be made to align the Center of thrust with the Center of Gravity. Original, this was a Tricopter design however I found this V-Tail configuration to be much more efficient.
The mission of this copter is to carry a camera payload to a predetermined altitude and location, hover about, then return home. So none of my video will be about proving how well this design can handle 3D or Sport Flying. First rounds of testings looks very promising, nice and stable in mild winds, gust about 10-14mph. In this video, only the Gyro and Accelerometer are used. Next rounds of testing will include GPS and Altitude holding.
