He was killed test flying the Canard after a small number were sold. If my memory serves me correctly the developer of the Canard, Dipl-Ing Hans Farner was a university professor. I was told they were no longer for sale but I made a trip to Switzerland anyway to try and talk them into selling one of the remaining 4 gliders. I came across the Canard in "Jane's All The World's Aircraft 1982-83" (the sailplane version is featured in the 83-84 issue) and contacted the factory for information. I was living in Scotland at that time and was interested in flying wave so I was looking for a foot launchable glider with higher usable airspeed. I was looking to buy one of these wings back in 1984. Velocity to never exceed, Vne 100 km/h (62 mi/h).If you can help, please send me any information you have. I don't have more information at the present, nor pictures. Its planform may have inspired the later ultralight design, the Goldwing. It had fiberglass construction with 3-axis controls, bomb-bay doors for the pilot's feet, and good performance. All flight speeds and all the different positions of the flaps refer to a generally good control and manoeuvrability behaviour of the Archaeopteryx and gives a feeling of safe flying to the pilot.The Canard 2FL is a canard rigid-wing model developed in the late 1970s or early 1980s in Europe by Avifiber (Dipl. The very harmonic and not tiring control behaviour is the result of a careful tuning optimization considering the effects and loadings of each rudder. The highly efficient fullspan flap and the airbrake are controlled by a lever located on the left handed side. Ailerons and elevator are controlled by the pilot with a right handed stick, the rudder with pedals. ControlsĪ conventional control mechanism is implemented in the Archaeopteryx basically used as in all common planes. A landing gear with a low touch down speed complete the safe landing procedure. The slow landing approach velocity and its effective airbrake allow a small spread landing approach on hang-glider sites. For all the different flap settings it shows a very friendly stall characteristic, avoiding dropping and risks of spinning during straight and curved flight manoeuvres. The around all axis aerodynamically contolled wingflap glider is flown like a conventional sailplane with comparable characteristics of flight, fight behaviour and controls. The takeoff speed of the Archaeopteryx is far less compared to common rigid wing hang-gliders and includes stability advantages of the longitudinal axis. Propertiesīesides the main launching method by foot, alternative methods like bungee, car-towing, winch-towing and aerotow using microlight vehicles are possible. Besides, the concept includes a high performance in fast and uncritical gliding as well. Excellent climb rates and an efficient riding out of extremely weak and slim thermals (microlift) are possible. Primary targets were set to minimize the mass, allowing slowest possible flight speeds and providing good manoeuvrability based on a friendly stall behaviour. Here is a description of the Archaeopteryx from the builder's website: ConceptĪ conventional aeroplane layout was followed for the Archaeopteryx, to avoid well known problems of flying wings. The Archaeopteryx is equipped with flaps, allowing for the performance necessary for a foot-launch. The design is intended to be foot-launched, car-towed, aerotow-launched, or with some other assistance. The Archaeopteryx is a foot-launchable ultralight glider being designed and built by ZHW (now Ruppert Composite) Archaeopteryx Archaeopteryx by Ruppert Composite
