A gyro is a simpler device than a helicopter. No collective needed except for jump-takeoff machines. There's no reason to complicate matters. One rotor with two-axis cyclic works quite well.

Control seems to be achieved for a Qaudrotor collective pitch powered quad and the results are remarkable. . I wonder what could be achieved with unpowered rotors with a pusher or puller prop.
Wow! That thing is cool. I had to watch it twice to wrap my head around how the reversible pitch blades function in flight. If they could build one to carry a pilot you could make a killing at airshows.
