A real-life A-10 Warthog weighs in at 30,000 lbs, and its engines produce 18,000 pounds of thrust. True to its nickname, the fighter isn't among the sleekest-looking things in the air. Rather, it's built to take—and inflict—a beating. Within a cockpit protected by a titanium "bathtub," a pilot can drop up to eight tons of bombs or fire a 30mm Gatling gun at 4,000 rounds a minute. With both wings attached, Selby's 5.5-to-1 scale model—constructed mainly of fiberglass, Kevlar, carbon, and aircraft-grade aluminum—stretches 10 feet across and weighs about 65 lbs dry. That made it among the largest models competing at Top Gun 2008.
