"What you are seeing is called aeroservoelastic instability. It occurs when the aerodynamic forces from an oscillating control system exceed the damping forces inherent in the structure. In other words, the controller and servos are shaking the…"
"If you do a search of"ArduVTOL-Wingcopter" you'll find that there is a tilt quad version without the front engine already flying. A servo tilts the quads and the autopilot changes as a function of tilt angle."
"If you go through the airframe design forum you'll find that someone has built this but tilts the quad rotor to provide thrust in horizontal flight."
"Jacob,
Great work on the video! I really enjoyed it.
The concept has a couple of significant problems, however. As the government found out with it's tail sitters, it is difficult it get the pilot into the aircraft. It sounds trivial, but you need…"

"The challenge with this is that you have to lift the weight of the fixed wing airplane with the quad rotor. On the other hand, the quad rotors don't do anything when e aircraft is in horizontal flight. The V-22 tilt rotor was developed to address…"
"The stall will occur at a fixed angle of attack for a given flap setting. The stabilizer position for the stall angle of attack is a function of the pitching moment that the stabilizer has to trim. The pitching moment is a function of flap position…"
