The BG-6 was introduced in 1939 and produced in both complete and kit form. It has no devices for glidepath control. A few factory-built ships were used as training gliders in World Was II.
The BG-12 series has established an enviable record as a homebuilt sailplane with around 350 kits or sets of plans having been delivered to customers. The prototype flew in 1956 using a modified BG-6 fuselage. The –12 A production version has a 15% thick 3-piece wing. A lighter 2- piece 18% thick wing was developed…
The Astir CS Jeans was of similar configuration to the CS 77, but with fixed wheel located ahead of the center of gravity, and a tailskid. This was followed by the Club II with similar fixed gear. The Club III has a fixed main gear ahead of the center of gravity, and a tailwheel. The…
The ASK-23 is a composite structure flapless early solo/ club sailplane designed as a successor to the Schleicher Ka-8 and ASK-18. It is the single-place counterpart of the two-place ASK-21 with cockpit layout similar to that of the latter’s front cockpit. It has a fixed gear and Schempp-Hirth type airbrakes.
Schleicher’s entry to the composite two-seat sailplane market, the ASK-21 first flew in 1979 and is approved for a number of aerobatic maneuvers. Schempp-Hirth type airbrakes (upper surface only), ailerons and elevators are operated by pushrods in ball bearing; the rudder is cable-operated. Wings attach with a tongue- and- fork connection and two pins. The…
The ASK-14, which first flew in 1967, was a low- wing, powered version of the Ka-6E with a 2- cycle, 2-cylinder Hirth engine driving a featering Hoffmann propeller. It features a retractable, single-wheel landing gear and spoilers. ASK-14’s took the second, third and fourth places in the single-place class of the first international motorglider contest…
The ASK-13 two-place tandem trainer was a development of the earlier Ka-7. The performance improvement was marginal, but the mid-wing design and improved canopy made for much better pilot visibility. The landing wheel is fixed and sprung with rubber cones, and the ship is fitted with airbrakes. In later models, a nosewheel was substituted for…
Designed as a dedicated 18 m. sailplane rather than an extended-tip 15 m. model, flapped self- launching ASH-26E claims better performance from being optimized for this span. The Midwest engine installation is distinctive from most previous mast mounted retractable engines in that the engine remains in the fuselage when the propeller is raised, permitting reduction…
The Astir CS (club standard) was the first sailplane designed and serially produced by Grob. It features composite (fiberglass/resin) construction, a large wing area, a T-tail and water ballast. A Standard Class Sailplane, the large wing area gives good low speed handling characteristics. The main gear retracts. A slightly improved version, the CS-77, was introduced…
