Seagull Models Kwik Fly MK III 63in ARF .46-55 (GP/EP) RC Aircraft Kit - SEASEA406

The Seagull Models Kwik Fly MK III (SEA406) is a 63-inch wingspan ARF aerobatic RC plane powered by either glow or electric, designed for pilots stepping into pattern flying and precision aerobatics. Based on Phil Kraft's iconic 1967 FAI World Championship design, this low-wing RC aircraft balances classic competition heritage with forgiving, trainer-friendly flight characteristics that suit pilots transitioning from basic flying into aerobatics. The ARF construction means the airframe arrives largely pre-built, reducing bench time and getting you to the field faster. With a 63-inch (160 cm) wingspan and a wing area of 744 sq in, the Kwik Fly MK III has the presence and stability needed for smooth, controlled aerobatic sequences.

Key Features

• Balsa and balsa plywood construction keeps the finished weight down to approximately 6.6 lbs (3 kg), supporting responsive, predictable handling in the air.
• Plug-in wing design simplifies transport and storage without compromising rigidity at the field.
• Large removable hatch provides straightforward access to the radio gear and flight battery, making electric setup and maintenance practical.
• Tricycle undercarriage supports stable taxi, takeoff, and landing behaviour on paved or grass strips.
• All hardware for both glow and electric power options is included — glow-powered pilots can run a 0.46–0.55 cu in two-stroke or 0.52–0.72 cu in four-stroke; electric pilots need a 0.35–0.45 size motor at around 830 Kv, a 50A ESC, and a 4S–6S LiPo in the 3200–5300 mAh range.
