Alpla AVo 60 Samburo / AVo 68V Samburo
This Austrian side-by-side two-seater motor glider was designed by Werner Vogel with the assistance of Professor Dr Ernst Zeibig, and is intended for training as well as cross-country an pleasure flying.
The cantilever low wings are of conventional wood and fabric construction with spoilers in the upper surfaces, and can be folded back to an overall width of 32ft 9.5 in (10m) for hangar storage. The fuselage is a fabric covered steel tube framework and the rear section of the two-piece cockpit canopy slides backwards for the pilots' access; the latter have dual controls. The cantilever tail unit has a low-set tailplane with a trim tab in the starboard elevator. The undercarriage consists of a non-retractable monowheel recessed into a fairing under the fuselage, and small outrigger wheels on nylon legs under the wings at about 40% of each half-span; there is also a steerable tailwheel, and the main wheel brake can also be used as a parking brake.
It first appeared as the AVo 60 Samburo with a 60hp Limbach SL 1700EA 'flat four' engine driving a two blade fixed-pitch propeller and with a slightly smaller fuel tank. The production AVo 68V first flew in 1977 and has a 68hp Limbach SL 1700E4 engine driving a two-blade variable-pitch propeller, and has higher weights than the AVo 60.
A total of 16 Samburos had been built by the Alpla-Werke Alwin Lechner OHG by the end of 1977, but production ended in January 1979.
