Stoddard Hamilton Sportsman 2+2

The Sportsman 2+2 is a four-place general aviation aircraft that is a tail-dragger, trike, float ready, wing folding, trailerable, high-utility aircraft, with ano ptional second row “jump seat” for 2 rear-seat passengers (up to 5’ tall).

“The Sportsman is the Glastar’s big brother”, said Ted Setzer, V.P. of Research & Development at Glasair Aviation, and the project manager on the Sportsman. The Sportsman has a nearly 1,000 pound useful load, and, with 2 pilots and full fuel, the Sportsman will not only haul over 300 pounds of gear, cargo, or extra passengers, it will easily handle all of the bulky stuff” said Setzer. Loaded, it can cover 600 miles in 4 hours and still have a ½ hour fuel reserve.

The Sportsman was test flown in the tail-dragger configuration on Goodyear 26” tundra tires. The prototype Sportsman was outfitted with the optional second row “jump seat” and powered by a normally aspirated, 180 hp Lycoming O-360, swinging a Hartzell 80” constant speed propeller. Even though the prototype was being flown with the draggy tundra tires and without any wing-to-strut or strut-to-fuselage fairings, it is seeing cruise speeds of 147 mph/130 kts and yet stalls at 49 mph/43 kts. With the 26” tundra tires, the Sportsman boasts 18” of prop clearance even with the 80” Hartzell propeller. On standard 6.00 x 6.00 wheels and tires and a 74” cruise prop, pilots can expect to have similar clearances for rough field operations.

Based upon Glastar floatplane performance data, the Sportsman is expected to have takeoff runs in the 9 – 12 second range.
