Historically, TOPMODEL (France) became known as a pioneer in 3D flight. Today this reputation is further enhanced with the launch of the world's first production model 3D sailplane.

The Kulbutin is a sailplane for the more experienced modeler who is looking for something different or, perhaps a new challenge. Looking at this plane you will know it is unlike any other sailplane. Its generous side area and large rudder allow for unbelievable knife-edge flight. An exclusive new mechanism provides incredible elevator control by allowing the full flying stabilizer to rotate through almost 180° (see picture below). These extreme control throws allow aerobatic maneuvers never before possible with any sailplane. We strongly recommend the use of dual rates. New figures are now possible such as the “Kulbuto” Plunge or the "Parkinson” Loop (see drawings below). This sailplane is so capable of wild maneuvers, you will soon be inventing you own. Due to its light wing loading, the KULBUTIN can also fly in very light wind conditions, a rare characteristic for an aerobatic sailplane. Designed essentially for slope soaring where you can obtain long duration 3D flights, the Kulbutin can also be aero towed to enjoy 3D flying at your favorite sod farm or thermal field. With the Kulbutin, sailplane enthusiasts are finally able to enjoy the thrills of 3D flying. This is a very complete kit that goes together quickly. A fully illustrated manual will ensure an enjoyable assembly experience. All components are pre-finished and are of top quality. A large decal sheet will allow you to dress up your model to look just like the one pictured here. The Kulbutin is a super fun model for the third millennium that breaks down so you can take it everywhere!
