Yes, indeed! and that tells us something important: the gyro can be simple and inexpensive to build. It's a local optimum in design space. But you pay for that in controllability.
Here's how I described it in the post:
Taking off in a fixed-wing airplane is fairly easy; you shove the throttle to full power and steer in a straight line, and when the airspeed indicator says you're going fast enough, pull gently back on the yoke and away you go.
In a gyro, not so much. First, line up on the runway and push the stick full forward. Then, holding the brakes, move the throttle up to about 2000 RPM, or the engine will stall when you do the next part. Release the rotor brake (wheel brakes still on) and engage the pre-rotator. You have to slowly edge the throttle up as the rotor accelerates, until it reaches 200 RPM. Now, in quick succession, release the wheel brakes, pull the stick full back, advance the throttle up to about 4000, and steer straight down the runway. As you accelerate, the relative wind will bring the rotor up to about 400 RPM. This enough to begin generating lift, which pulls you up onto your back wheels, doing a wheelie down the runway. You must accommodate this instantly with the stick; otherwise the angle change of the rotor shaft with the wheelie will tilt the rotor too far back and pull you over backwards.
Congratulations! you have now formed a wing. Still balancing on your back wheels, use it to take off. Continue accelerating down the runway, noting that the torque from the propeller will be trying hard to make you turn left; counteract this with pressure on the right rudder pedal.

The best way to visualize the rotor disc as a wing is to see that it induces the same lift-producing circulation patterns as a solid wing, but notice that the airflow can go
through the disc. As you see, the flow is coming up through the front and going down through the back part of the disc. This pushes up in front and down in back; but by the magic of gyroscopic precession, it tries to tilt to the right, so push the stick to the left to counteract it.
Now the quadrotor is also a local optimum in design space -- look at how many there are. With a quadrotor, you don't have to worry that every maneuver is going to turn your craft into a pendulum, and leave you trying to counter the resulting oscillations. You don't get the extreme pitch excursions a gyro does even in normal operations. Combine them and maybe, just maybe, you could get something that is stable, agile, and controllable at the same time.
