A heliplane operates with a fixed wing at high velocities, and particularly at high advance ratios, while using a rotary wing maintained in motion at all speeds. At high advance ratios, the rotor wing eventually may be rotated primarily to maintain its stability, rather than depending upon the majority of lift. Meanwhile, a collective pitch control is provided and located between pilot and copilot. A single control provides control of both collective pitch and throttle by both pilots. One pilot will have to operate the control with the left hand, while the other may use their right hand. Nevertheless, both throttles push away from the pilot, regardless of which one is in control of the aircraft, while a single collective lever is relied upon.
