How do helicpoters fly?

Answer 1

That depends on if you're asking how they're powered or how they're controlled. Helicopters are powered by an engine that goes through a series of gears to the rotors at the top. They are controlled by the cyclic (control stick) in the cabin and the collective (throttle (more or less)). The cyclic then connects to the squash plate at the rotors and adjusts the angle of attack on the blades as they reach that point. That then maneuvers the helicopter. The collective pushes the squash plate up to the rotors to increase the angle of attack to take off.
