Something that's been bugging me is a curious thought. Do helicopters have throttles like airplanes or are they just always full throttle?
Helicopters with a piston engine have a motorcycle twist type throttle on the end of the collective pitch lever. As the load on the the rotor system is increased by raising the collective pitch lever, more throttle/power is required to maintain the required operating rpm. Helicopters with a turbine engine run at a constant rpm and a device on the engine senses the changing load and automatically maintains constant rpm. Engine rpm in a turbine engine is so high that it's not really possible to control it manually. Many turbine powered helicopters have throttle levers on the center or overhead consoles, similar to airplanes. At least that was how it was with the ones I flew.

But....choppers do have wings. They just rotate!
Actual at every chopper has at least 2 wings and some have 4 or more wings ...

Actually, speed is controlled by a combination of of increased or decreased collective pitch angle of the rotor blades and the cyclic pitch control (aka, control stick) which controls forward and rearward movement of the helicopter as well as lateral movement. In flight, the throttle is used to maintain a constant rpm.

Great, Funny- I never heard that one (most likely originated by someone that likes 'wings')

Airplanes fly. Helicopters just beat the air into submission.

That's quite an accomplishment. Then they use that air to do things airplanes can't. I really enjoyed flying helicopters.

Obviously you understand helicopters

I think we used to use the term, "Thrashing the air."

A helicopter is by definition a rotary-winged aircraft, but the "wing" sure looks more like a blade to me, too.

That is how we used to refer to them as--blades.

Unless they're Hueys, then they're "barn doors"!
The real principle of helicopter flight is mirrors and magic!

I can't recall any mirrors except when the crew chief was inspecting the Huey, but I do remember a lot of magic in those old birds.
