flying it as fixed wing only aircraft) the weight comes down to 3.7Kg, but that obviously requires a landing strip. By removing the quadcopter components (ie. All up weight in it's quadplane form,including batteries and camera, is around 4.8Kg. The wingspan of the aircraft is around 2m and the quadcopter frame is 1m (measured diagonal). Rather, this Instructable covers the mods required to convert the fixed wing aircraft into a hybrid quadplane, capable of autonomous flight and able to carry sensors required for technical tasks as mentioned above. This Instructable is not intended to deal with the basic steps required to build the kit into a "standard" RC model - those steps are fairly straightforward and covered in the manufacturer's instruction manual. The aircraft I chose as the basis for this concept is called a Quanum Observer, which is available as a kit from Hobbyking (it is also sold by other retailers under the name of Volantex Ranger-Ex). (the second video shows a typical photogrammetry/3D model application). High resolution hard-mounted stills camera for photogrammetry, terrain modelling, crop monitoring in agriculture, etc. Stabilized video for applications in conservation, security, Search & Rescue, surveillance, etc.(see first demo video).Ģ. The drone is dual purpose in the application sense too, because it can be fitted with two sensor types, depending on the task required:ġ. The reduced weight in this form gives around 80mins flight duration and 70Km range. If a runway is available to use for launch and landing, then the rotary wing components can be removed in a few minutes for fixed-wing only flight. A typical quadcopter can only fly for around 15 mins and will struggle to cover more than 10Km in a single flight, whereas this quadplane can fly for nearly an hour and cover around 50Km. The hybrid or "Quadplane" concept combines the best of both worlds: Duration,speed and range of a fixed wing aircraft with the vertical flight aspects of a rotary wing aircraft. The end result is a very capable multi-purpose drone, ideally suited to a range of technical applications. This Instructable shows how I built a VTOL (Vertical Take-off and Landing) hybrid drone, aka "Quadplane", starting with a very basic fixed-wing radio control aircraft kit and customizing it with off-the-shelf quadcopter components.
