Design and development
The Questar Open Aire was designed to comply with the US FAR 103 Ultralight Vehicles rules, including the category's maximum empty weight of {{convert|254|lb|kg|0|abbr=on}}. The aircraft has a standard empty weight of {{convert|220|lb|kg|0|abbr=on}}.
The aircraft features a strut-braced high-wing, a single-seat open cockpit without a windshield, fixed conventional landing gear without wheel pants and a single engine in pusher configuration.
The Questar Open Aire is made from bolted-together aluminum tubing and wood, with its flying surfaces covered in doped aircraft fabric. Its {{convert|28.66|ft|m|1|abbr=on}} span wing has a wing area of {{convert|124.0|sqft|m2|abbr=on}} and is supported by "V" struts. The acceptable power range is {{convert|30|to|40|hp|kW|0|abbr=on}} and the standard engines used are small {{convert|30|hp|kW|0|abbr=on}} two-stroke powerplants.
The aircraft has a typical empty weight of {{convert|220|lb|kg|abbr=on}} and a gross weight of {{convert|450|lb|kg|abbr=on}}, giving a useful load of {{convert|230|lb|kg|abbr=on}}. With full fuel of {{convert|3|u.s.gal}} the payload for the pilot and baggage is {{convert|212|lb|kg|abbr=on}}.
The standard day, sea level, no wind, take off and landing roll with a {{convert|30|hp|kW|0|abbr=on}} engine is {{convert|100|ft|m|0|abbr=on}}.
