- Nota adicional1
- Since the fuselage of the helicopter, with a single main rotor, is suspended from a single point and has considerable mass, it is free to oscillate either longitudinally or laterally in the same way as a pendulum. This pendular action can be exaggerated by over controlling; therefore, control movements should be smooth and not exaggerated.

Because the helicopter´s body has mass and is suspended from a single point (the rotor mast head), it tends to act much like a pendulum.
