The AddictionX is a popular model plane allowing for spectacular high precision acrobatics. In addition to more common barrel rolls and vertical loops, its extremely light wing loading and high motor thrust to weight ratio provides expert flyers with capabililies such as precise vertical hover and knife edge maneuvers.
What if this kind of flying could be performed by an autopilot? Lead Arduplane developer Andrew Tridgell and the Ardupilot development team got started towards doing just that. Building up on previous VTOL work such as Ardupilot support for quadplane, tail sitter, tilt rotor and tilt wing VTOLs along with fully autonomous inverted flights, Tridge interfaced Ardupilot to the popular RealFlight flight simulator, and successfully flew the simulated AddictionX model, including vertical hovers, with Ardupilot.
Coming up in the near future: Tridge actually owns an AddictionX, and expects to fly one with Ardupilot. Also coming up with Ardupilot: ArduSoar, a soaring "extension" of ArduPlane for gliders. Stay tuned!
