Seagull Models Pattern Kwik Fly MK III 63in ARF .46-55 GP/EP Yellow RC Aircraft Kit - SEASEA406Y

The Seagull Models Kwik Fly MK III is a 63-inch wingspan ARF aerobatic RC plane designed for intermediate to advanced pilots who want classic FAI pattern performance with modern build convenience. Finished in an eye-catching yellow scheme and carrying the SEASEA406Y style code, this fixed-wing aircraft is based on Phil Kraft's legendary 1967 world championship design — a low-wing pattern plane renowned for its balanced, predictable flight characteristics that groove through aerobatic manoeuvres without drama. The Kwik Fly MK III supports both glow and electric power systems, accepting .46-.55 two-stroke or .52-.72 four-stroke glow engines, a 10cc petrol engine, or a 0.35-0.45 size brushless motor with a 50A ESC and 4S-6S LiPo, giving you genuine flexibility in how you set it up. With a wingspan of 63 inches (160 cm), a wing area of 744 sq in, and a flying weight of around 6.6 lbs (3 kg), this RC plane sits in a practical size class that's capable at the field without being unwieldy to transport.

Key Features

• Balsa and balsa-ply airframe construction keeps the finished weight down to approximately 6.6 lbs (3 kg) while maintaining structural rigidity for aerobatics.
• Plug-in wing design makes field transport and storage straightforward — no tools required to remove or reattach the wing.
