A variable speed pitch control (or vari-speed) is a control on an audio device such as a turntable, tape recorder, or CD player that allows the operator...

move in a desired way. To tilt forward and back (pitch) or sideways (roll) requires that the controls alter the angle of attack of the main rotor blades...

variable-pitch propeller is a type of propeller (airscrew) with blades that can be rotated around their long axis to change the blade pitch. A controllable-pitch...

technologies improved, motor speed and pitch control could be achieved electronically by servo drive system circuits. A pitch shifter is a sound effects unit...

effects unit and intended for live performance. Pitch control is a simpler process which affects pitch and speed simultaneously by slowing down or speeding...

RC helicopters exist, of which some (such as those with collective pitch control) are more maneuverable than others. The more maneuverable designs are...

horizontal surface besides its main wing. The aerodynamic control and stabilisation functions in both pitch and roll are incorporated into the main wing. A tailless...

contrast, pitch control allows the blades to be feathered, so that wind speed does not affect the stress on the control mechanism. Pitch control can be implemented...

(the latter two also colloquially known as a control or joystick), governs the aircraft's roll and pitch by moving the ailerons (or activating wing warping...
