The Sting S3 is the latest in a generation of LSAs that have
been a part of the Sport Pilot scene for a number of years. The
airplane is manufactured in the Czech Republic by TL-Ultralight,
sro. A predecessor, the StingSport was the fifth light sport
aircraft to be certified in the USA. The S3 is the fourth
generation in a line of distinguished aircraft that includes the S3
(2008), the StingSport (2004), the Sting Carbon (2000) and the Star
(1996).
The design of the Sting S3 is a product of Miroslav and Petr
Kabrt, whose Vanessa Air company, in collaboration with Czech
Technical University of Prague, specializes in the design, analysis
and testing of whole-composite aircraft and aircraft components for
civilian and military applications.
The Sting S3 is a low-wing, tricycle-geared, single-engine
airplane manufactured from composite materials with two
side-by-side seats. The wing of the Sting S3 uses the MS (1)-0313
airfoil profile and is tapered. Wings are removable in as little as
30 minutes, and lock together through the fuselage in a manner
similar to sailplanes. The standard 100 horsepower Rotax
liquid-cooled, four-cylinder, four-cycle engine swings a 68-inch,
ground adjustable, three-bladed carbon composite propeller. The
airplane is designed to perform to the limits of FAA-specified
performance envelope for light sport aircraft.
The S3 has a cruise, (75% power) of 116 kts, a clean stall of 39
kts, dirty stall of 34 kts and a demonstrated crosswind component
of 17 kts. Climbing 1000 fpm at best rate, the S3 uses 295 ft. for
takeoff (over a 50 ft. obstacle, that translates to 745 ft), and a
landing roll of 345 ft (50 ft. obstacle -- 1020 ft).
