Design and development
The Calypso line all feature a strut-braced high wing, fixed conventional landing gear with optional wheel pants and a single engine in tractor configuration.
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 {{convert|8.84|m|ft|1|abbr=on}} span wing has a wing area of {{convert|11.6|m2|sqft|abbr=on}} and is supported by "V" struts and jury struts. The cabin width is {{convert|61|cm|in|abbr=on}}. The acceptable power range is {{convert|40|to|65|hp|kW|0|abbr=on}} and the standard engines used are the {{convert|40|hp|kW|0|abbr=on}} Rotax 447 or the {{convert|50|hp|kW|0|abbr=on}} Rotax 503 two-stroke powerplants.
The Calypso 1A has a typical empty weight of {{convert|155|kg|lb|abbr=on}} and a gross weight of {{convert|285|kg|lb|abbr=on}}, giving a useful load of {{convert|130|kg|lb|abbr=on}}. With full fuel of {{convert|40|L}} the payload for the pilot and baggage is {{convert|103|kg|lb|abbr=on}}.
The standard day, sea level, no wind, takeoff with a {{convert|40|hp|kW|0|abbr=on}} engine is {{convert|61|m|ft|0|abbr=on}} and the landing roll is {{convert|46|m|ft|0|abbr=on}}.
The manufacturer estimates the construction time for the Calypso 1A from the supplied kit to be 300 hours.
