autogyro

I don't know what the overall efficiency of an autogyro is, I'm guessing there might be an issue there.

Crypto is closer to autogyro than automobile in adoption, and there is no guarantee that will ever change.

Sounds like an autogyro, indeed one of the lightest and cheapest ways to build a plane.

Once airborne, autogyro planes can safely descend without relying on power or even a functioning engine.

Well you could make a drone, but a lot of drones are used for hovering and an autogyro cannot hover.

That video scares me on multiple levels, but shouldn't an autogyro be able to slow down horizontally and autorotate to the ground?

The complexity of the conventional helicopter method is not only providing control, but also a considerable amount of safety by enabling autogyro capability.

That said, if it were to build a flying-machine an autogyro is the only kind I'd be willing to get into and fly slowly over the water like JP does.

All I want is an electric or hybrid autogyro equipped with cutting-edge technology and sensors.

The inertia of the rotor helps a lot stabilize an autogyro.

Most helicopters can autogyro - that means they can land without working engine, using air flow to speed up the rotor, and then using the rotor to slow down the fall to relatively gentle landing.

* Can't autogyro, so running out of fuel is much more serious!

This lack of autogyro is already restricting the quadrocopter setup to "let it crash" dimensions and the same well be true for this admittedly very clever duocopter.

The only transition that occurs is change in pitch of rotor blades to go from “powered” state into “passive autogyro” state.

Really, as far as most procrastinators are concerned, you might as well call procrastination "Autogyro Congee 4000" because at least that rewording might seem novel enough to warrant some hope.
