Seagull Models KA8B 3m White RC Glider - SEA137A

The Seagull Models KA8B Glider (SEA137A) is a 3-metre wingspan RC sailplane designed for pilots who want a large-scale, graceful thermal soarer with classic glider lines. Based on the iconic KA8B full-scale sailplane, this model captures the long, slender wing profile that makes the real aircraft so recognisable, and translates it into a stable, rewarding flying experience suited to intermediate RC pilots. The 3-metre span gives it excellent glide performance and visibility in the air, making it a serious choice for soaring enthusiasts.

Key Features

• 3-metre wingspan delivers a long glide ratio and strong thermal-soaring capability typical of classic sailplane designs.
• Based on the real-world KA8B glider, with scale-accurate fuselage and wing proportions finished in white.
• Large span improves in-flight visibility and provides a stable, predictable flight envelope suited to pilots stepping up from smaller gliders.
• Designed for electric power conversion or tow launch setups, giving flexibility in how you get it airborne.
• Part number SEA137A from Seagull Models, a manufacturer known for large-scale fixed-wing and glider kits.
