The TeST TST-10 Atlas is a single-seat, standard class sailplane, with a 15 m (49 ft 3 in) wingspan, manufactured by TeST Gliders in The Czech Republic. It is available both as a pure glider (TST-10) and self-launching glider (TST-10M).^[1]

Design and development

The TST-10M Atlas was designed for recreational, club-class flying, enhanced by the convenience of self-launching. It is made mostly of composite structure. The fuselage is made in the negative mould together with the fin. The wings also use composite material and have no ribs within the wing. Early iterations of the Atlas utilized a wooden spar of built-up construction; current versions utilize a carbon fiber spar. The typical sailplane monowheel landing gear is fixed; a castering tailwheel and wingtip wheels assist powered taxiing.{{Citation needed|date=September 2011}}

Assembly of the glider is typical of modern gliders, with forked wing spars joined by two steel pins. The wings each weigh only 32 kg (71 lb).{{Citation needed|date=September 2011}}

The self-launching version is powered by a 30 kW (40 hp) Rotax 447 engine externally mounted on a retractable mast which drives a two-bladed wooden propeller. Engine extension and retraction is performed by an electric motor.{{Citation needed|date=September 2011}}

The published glide ratio of the Atlas is 40:1. Best glide speed is 88 km/h (55 mph, 48 kn); V_NE is low for a contemporary glider at 180 km/h (110 mph, 97 kn).{{Citation needed|date=September 2011}}

An improved variant, the TST-10MB was released in spring 2008. It differences from the original TST-10M in having a retractable undercarriage, automatic connection of controls for wing to fuselage assembly, a new seat shape, a larger fuel tank and optimized winglets.{{Citation needed|date=September 2011}}

Operational history

There are roughly 40 TST 10M Atlases flying, two of which are in the United States, where they have been registered with the FAA in the Experimental E-LSA category.{{Citation needed|date=September 2011}}

In mid-2010 15 TST-10s appeared on civil aircraft registers of European countries west of Russia.
