Hangar 9’s giant-scale legal Sundowner Formula 1 80-inch ARF is a true sport performer with an aggressive racer fuselage design that makes it look like it’s traveling 100 mph even when it’s standing still. This sport performer looks great, down low on the deck. And then, experience a high-flying adrenaline rush as this spirited, agile racer streaks into a turn at high speed. Because of its smooth flight characteristics and precise sport handling, pilots will feel comfortable even at 120+ mph, making the Sundowner the perfect plane for entry-level giant-scale racing. Although the Sundowner is characterized as a racer because of its fiery body design, it is truly a sport aerobatic model geared for performance. The 1.80-size Sundowner ARF can be powered for performance using a variety of gas or glow engines, or converted to electric power for clean, no-fuss flying.

The two-piece plug-in wing and stab make transporting this giant-scale aircraft a more compact process. A removable top hatch provides admittance to the plane’s interior, and the servo hatch located at the rear of the plane provides access to the rudder and elevator servos. This ARF includes high-quality giant-scale hardware and aluminum wing tubes which provide extreme durability at low weight. Hangar 9 even outfits the Sundowner with a lightweight, painted pilot figure—complete with racing helmet.
