Source sentences:
text: If the pilot pushes the cyclic forward, the rotor disk tilts forward, and the rotor produces a thrust in the forward direction.
text: Each rotor produces both a thrust and torque about its center of rotation, as well as a drag force opposite to the vehicle's direction of flight.
text: This mode allows the rotor to produce a thrust upwards (by using negative pitch) which, when the model is inverted, allows sustained inverted flight.
