Aircraft Description

The GT- 500
The first & only Sport Airplane in the world to receive FAA certification in the Sportplane class of the Primary category.
It is remarkably docile and easy to fly. The dual three-axis controls are responsive without sacrificing low speed stability. The adjustable trim and flaps allow for positive slow flight and gentle stalls at about 39 mph. The GT-500 cruises from 55-80 mph, with a top speed of around 90 mph. Only approximately 140 feet is needed for the take-off roll. A generous useful load capacity (see specifications) can easily accommodate two people and some extra gear.

The Sport 2S is the latest evolution in Quicksilver's open cockpit design.

The Sport 2S development program began with the goal of producing the best side-by-side trainer ever. Featuring strutted wings, wider cockpit, rugged aluminum steerable nose wheel, and larger wheels, the Sport 2S combines the many suggestions and comments of ultralight enthusiasts and professionals with Quicksilver's extensive designing, engineering, and R & D testing to full fill that goal.



is ideal for the recreational flyer and flight schools. Its high lift partial double surfaced wings give it an exceptionally short take off roll and predictable handling at very low flight speeds. These characteristics make the MXII SPRINT easier to learn to fly than anything in its class. When equipped with floats, the MXII SPRINT's high lift wing will get you out of the water quicker and landing slower. Like all Quicksilvers, the MXII SPRINT's simple design and bolt together construction make preflight inspection and maintenance a breeze.
