Trike cosmos phase ii
The Cosmos Phase II and Phase III are a series of French two-seat flying wing ultralight trikes that were produced by Cosmos ULM of Fontaine-lès-Dijon and now by Cosmos Ultralight of Puente de Ixtla, Mexico. The aircraft are supplied as factory completed aircraft and are not available as kits.

Design and development
The series was developed from the earlier Cosmos Bison, adding larger seats, landing gear suspension and a new engine mounting system to reduce vibration. It was designed to comply with European Fédération Aéronautique Internationale microlight classification. It features a cable-braced hang glider-style high-wing, weight-shift controls, a two-seats-in-tandem open cockpit, tricycle landing gear and a single engine in pusher configuration.
The aircraft wing is made from bolted-together aluminum tubing, with its single, or optionally double-surface, wing covered in Trilam sailcloth. The wing is supported by a single tube-type kingpost and uses an "A" frame control bar. A variety of wings and engines can be fitted, each with a different model designation. When equipped with a 37 kW (50 hp) Rotax 503 or 48 kW (64 hp) Rotax 582 two-stroke engine the aircraft is designated as a Phase II and when equipped with a 60 to 75 kW (80 to 101 hp) Rotax 912 four-stroke engine is designated as a Phase III. Wings used include the double surface Top 12.9, Top 14.9, Chronos 16 and the single surface Zoom 19. The wing designation reflects the area in square metres. The landing gear features gas-filled shock absorber suspension on all three wheels, nose whweel steering and a nose wheel-mounted drum brake, as well as a parking brake. The aircraft can be disassembled for storage or ground transportation, taking half an hour for set-up.
The series has a wide range of options, including a glider aero-tow kit, floats, salt-water protection, ballistic parachute and dual controls for flight training.
