Schweizer SGS 2-8 / TG-2 / LNS-1


Ernest and Paul Schweizers 2-8 two-place was the first large scale production Schweizer design and the first dozen were built for private owners and clubs.

An all metal glider has a strut braced wing with upper surface spoilers for glidepath control.

A batch was built for the U.S. Army Air Corps for the intial instructor training class at Elmira and subsequently more were ordered as the TG-2. Production was limited by the availability of aluminum. The U.S. Navy and Marines ordered 2-8’s which were designated LNS- 1. Pre World War II civilian gliders were impressed into the USAAC as the TG-2A. After the war. TG-2’s were sought after as they were light, rugged and all metal, despite a low 116 kph/ 63 kt/ 72 mph redline.

Even so, Bob Stanley and Ernie Schweizer made a goal flight from Elmira Washington, D.C. (373 km / 232 miles) and Dick Johnson set a 499 km./ 310 mile multi-place distance record, both in 2-8’s.

The ship is unusual in that it is mainly fastened with PK self-tapping sheet metal screws and there are very few rivets. The empty weight of 204 kg / 450 lb is the original published figure. 2-8’s which remain active have empty weights in the 236-263 kg / 520- 580 lb range. The sturcture is metal/ fabric, 1-spar, 1-strut-braced wings; metal/ fabric tail; steel-tube/ fabric fuselage.

An example of a LNS-1 belongs to the National Museum of Naval Aviation at Pensavola, FL.

The Vintage Sailplane Association has copies of the military manuals, drawings of the color schemes and paint chips available.
