The Aerotique Parasol is an American ultralight aircraft that was designed as an ultralight version of the 1926 vintage Heath Parasol. The aircraft is a parasol-wing aircraft and is strut-braced, has conventional landing gear, a single seat, an open cockpit, and a single engine in tractor configuration. It was originally produced by Yesteryear Aviation and later by Aerotique Aviation. The aircraft was supplied as factory-built only.
The aircraft was designed to comply with the US FAR 103 Ultralight Vehicles rules, including the category's maximum empty weight of . The Parasol's factory standard empty weight was .
The aircraft's fuselage is built with an aluminium tube structure, with wooden wings, all covered with doped aircraft fabric covering. Early production models used wooden wing ribs, while later models transitioned to aluminium ribs. Its span wing uses parallel lift struts supported by jury struts and flying wires. The wings are removable for transportation or storage and take about an hour to remove. The factory installed engine was the Rotax 277, single cylinder, two-stroke powerplant of . Other than the engine and the wheels, all parts are certified aircraft parts.
The Parasol has conventional three-axis controls, including half-span ailerons. The main landing gear is bungee-suspended and the tail has a steerable skid. Brakes were optional and taxiing the aircraft without them was described as "a little tricky".
As is the case with many parasol designs where the pilot sits directly underneath the wing on the aircraft's center of gravity, the cockpit access is restricted by the close proximity of the wing.
