The K 8 was derived from the earlier Ka 6 design as a simple single-place sailplane with dive brakes using construction techniques similar to the Schleicher K 7, simplified for amateur construction from kits. Emphasis was on rugged construction, good climbing ability in thermals and good handling characteristics.

Seagull's Ka8B Glider is a beautiful rendition of this timeless piece of sailplane history. With its graceful 3 meter wingspan, optional speed brakes and fixed landing gear, this Ka8B is sure to be an exciting airplane for any sailplane enthusiast.


  • Perfect for ridge slope soaring or towed to height looking for thermals
  • Efficient airbrakes
  • Designed as an intermediate to advance sports trainer flyer
  • High wing airplane that is easy to fly and quick to assemble
  • The airframe is conventionally built using balsa, plywood and veneer to make it stronger than the average ARF glide
  • Fixed undercarriage for great "run on landings
  • Releasable tow hook point
  • Detailed scale cockpit with ultra lightweight pilot included
  • The current popular color scheme which makes the KA8B stand out and look timeless
  • Covered in genuine UltraCote
