Design and development
The single-seat Calypso 1 is made from a combination of wood and metal with its flying surfaces covered in doped aircraft fabric and a fibreglass cowling. Its 8.84 m (29.0 ft) span wing has a wing area of 11.6 m2 (125 sq ft) and is supported by "V" struts and jury struts. The cabin width is 61 cm (24 in). The acceptable power range is 40 to 65 hp (30 to 48 kW) and the standard engines used are the 40 hp (30 kW) Rotax 447 or the 50 hp (37 kW) Rotax 503 two-stroke powerplants.
The Calypso 1A has a typical empty weight of 155 kg (342 lb) and a gross weight of 285 kg (628 lb), giving a useful load of 130 kg (290 lb). With full fuel of 40 litres (8.8 imp gal; 11 US gal) the payload for the pilot and baggage is 103 kg (227 lb).
The standard day, sea level, no wind, takeoff with a 40 hp (30 kW) engine is 61 m (200 ft) and the landing roll is 46 m (151 ft).
The manufacturer estimates the construction time for the Calypso 1A from the supplied kit to be 300 hours.
By 1998 the company reported that 12 kits had been sold and five Calypso 1s were completed and flying.
