Quicksilver Aeronautics GT 400
These figures describe a typical build. Each aircraft of this design was built by its owner, and the one you are looking at may differ.
The Quicksilver GT 400 is a single-seat strut-braced ultralight-type aircraft from 1984: a 30 ft Dacron-covered aluminium-tube wing, a pusher two-stroke of about 50 hp, tricycle gear and a 125-hour assembly kit. Air-Tech's figures are 64-78 mph cruise, a 29 mph stall, a 65 ft ground roll, 1,450 fpm and 264 lb useful on a 306 lb airframe.
Most GT 400s are single-seat ultralights and the ones in the registry are those an owner chose to register as experimental or light-sport, so the paperwork and what it permits is the first question; the two-seat GT 500 is a different aeroplane with a primary-category type certificate. Ownership is an ultralight's: a two-stroke that lives on careful mixing, decarbonising and rubber changes, sailcloth that sunlight destroys, and a 60 knot machine for the pattern and the local area. Everything else is whatever the builder fitted, and the aircraft's own weight-and-balance and condition inspection history are the record. Quicksilver and its dealers still sell parts and sails. No asking price for a flying example was found.

- Liquidity: class median 20.
- Each of the five categories places the model within its peer class, from 0 (the worst of the class) to 10 (the best): a position among comparable models, not a grade. The overall score is the sum of the categories shown that are scored, out of 10 for each (50 when all five are); it is given only when at least 4 of the five are scored, and it can be set against another model's only when both are in the same peer class and scored on the same categories. When accident record and severity cannot be scored because the model has too few records, the other three give a partial score out of 30, labelled as such; it is never set against a full score.
