This helicopter has Speedometer (6 axis accelerometer) hooked up to the cyclic. Only two angular outputs of the speedometer are being relayed back in to the cyclic. This is shown in the start of the video where the swashplate delays in moving in to the same orientation as the body of the helicopter. The speedometer is applying cyclic to try and dampen the movement. The same as a flybar. Where via precession, The pitch on the blade are moved to dampen any change in orientation. Here I'm doing it electronically. The flybar lookalike on the hub is a precession bar. The idea on this unlike a Flybar is to increase the overall mass of the rotor disk. Therefor increasing it's tendency to resist motion, the paddles on the end of it are to create some air resistance. They basically act as a big air brake. It slightly improves stability and noticeably decreases vibration. Also the Rotor head semi rigid now, Therefor the blades can pivot relative to the main rotor shaft But are dampened so they will level out if moved.
