L13 L19 The original L13 Blanik was built in 1958 and several thousands of them are flying worldwide. The two-seat, all-metal L13 evolved into the L23 Super Blanik. The new glider retains the excellent flying and maintenance characteristics of the L13, while visibility and handling are further refined. Among the many improvements are the new more »


Gus Briegleb began designing and building sailplanes in the 1930s. In 1940, he came up with his sixth design,the BG-6, and initially sold it in kit form. As a utility-training glider, it had a lift-to-drag ratio of 16 and a minimum sink of about 3 fps. The BG-7 was an improved version using the same more »


Designer R.E. Schreder built the RS-15 to OSTIV Standard Class specifications. Licensed in the amateur-builtexperimental category, its assembly is relatively simple with most major components pre-made to cut buildingtime to about 500 hours. The shoulder-type wings are all-metal with the exception of polyurethane foamribs. Provision for a 200-pound water ballast is inside the wing’s box more »


A quick glance at the gross weight or wingspan of the Calif motorglider or sailplane should tell the enthusiast that the pair are not ordinary aircraft. With 66.9 feet of wingspan, the A-21SJ is the only production turbojet-powered sailplane in the world. It offers side-byside seating and all-metal construction. The engine retracts into the fuselage more »


DG300 DG600 DG800 DG1000 Gerhard Glaser, owner of a civil engineering business, and Diplom Ingenieur Wilhelm Dirks, founded the Glaser-Dirks Flugzeugbau GmbH company. In 1972, they built their first glider, the DG-100. Glaser-Dirks produced 105 DG-100 and another 222 units have been produced later at the Elan factory. In 1977 the 15-meter class sailplane DG-200 more »


The Katana X-Treme was born in Austria in 1990. The all-composite two-seater flies with 80, 100, and 115-hp Rotax engines, operating as both a sport plane (under the name HK36 Super Dimona in Europe) and as the Eco Dimona, a variant modified for surveillance and observation. This model features a movable Wescam camera and cockpit more »

GROB G-103

The biggest improvement for the G-103, the successor to the Twin Astir, came from modifications to the ailerons. Pilots reported a substantial improvement in feel (with the steel control pushrods) and overall roll re-sponse for greater aerobatic performance. The mains, which sits aft of the aircraft’s center of gravity in a fairing, features a hydraulic more »


Libelle 205 Kestrel Hornet 206 Mosquito 303 Glasflugel 304 Glasflugel was founded by Eugen Hänle in 1962 and carried the logo of a dragonfly (in German “Libelle”). In May 1975, financial problems lead to a co-operation with the firm Schempp-Hirth. Until 1979 Glasflügel carried the name “Holighaus & Hillenbrand” and was then dissolved in 1982 more »


Vernon Oldershaw’s motorglider features a retractable power plant that can be used for takeoff and climb to soaring altitude. A 31-hp Yamaha snowmobile two stroke flat-twin engine drives a wooden pusher propeller and feeds from a N-gallon fuel supply. The shoulder-type wings are built with a spruce spar, plywood ribs, and plywood skin; the wing more »


  The Orlik 2 first flew in 1938, and an improved variation, the Orlik 3 competed in the 1940 Olympic Games. It had airbrakes beneath the wings. The design briefly held a world altitude record in 1948 of 30,000 feet.


  The PIK motorized glider has a manually retractable engine and propeller. The Rotax 503 500cc two-stroke two-cylinder engine produces 43 hp at 6,200 RPM. With double carburetors and resonance exhaust system, the whole snowmobile engine has been redesigned and built to aircraft requirements. The propeller is belt driven giving a 1:2 reduction. When not more »


  The only glider manufactured by Swiss aircraft manufacturer Pilatus was the B4. About 300 were produced beginning in 1972 until the Japanese company Nippi bought the rights to the design. The P4 is all metal and economical to maintain, and has good acro capabilities.


This sleek motorglider is essentially a stock KR-1 with longer wings and a bigger tail. For a wing curve, an RAF-48 standard KR-1 airfoil was used for the center section and the GA(W)-2 airfoil for the replacement outer panels. The outer wing section provides a clean and responsive curve for use with a spoiler/flap control, more »
