Helicopter Style Drones
Similar to a plane, a helicopter has specific components that control its movement. A helicopter (and quadcopter) will be able hover in one spot, unlike planes.
Parts of an Helicopter:
Swash Plate: controls pitch, angle of main rotor blades, and direction (and hover)
Flybar: stabilizes flight
Rotor Blades: Provide lift
Tail Rotor: counterforce to the rotor blades and helps to steer
Tail Fins: keep helicopter stables
