A QuadPlane is a combined fixed wing and MultiCopter aircraft. This sort of aircraft brings the benefit of vertical takeoff and landing, significantly greater speed and range of travel, and the ability to hover and perform copter-like tasks at the destination.
QuadPlane is built upon Plane, but adds control over between 4 and 8 horizontal rotors. Additional modes and commands allow a QuadPlane to take off, land and fly like a copter, and to smoothly transition between the Plane and Copter-like modes in both automatic and autopilot-assisted modes. The additional rotors can also provide lift and stability in normal Plane modes.
Installing the Firmware¶
QuadPlane support is in APM:Plane releases from 3.5.0 onwards. The normal instructions for installing the Plane firmware apply.
When you install the plane firmware and look in the parameter list you will see a Q_ENABLE parameter. That defaults to zero, which disables QuadPlane support. Setting Q_ENABLE to 1 will enable QuadPlane support. You then need to refresh your parameter list to see all the other QuadPlane options. All QuadPlane specific parameters start with Q_.
