This is one of Top Models most interesting sailplanes. The Kulbutins full-flying elevator is capable of 90 degree throws. With the massive elevator throws and large, full span ailerons, "Slope 3D" is possible. The tall but narrow fuselage design gives the Kulbutin great knife-edge flight characteristics as well. Although designed for the slope, the Kulbutin's light wing loading means that it thermals well and performs well in light wind conditions. With addition of electric version you do not need slope with strong wind, from now on you can enjoy this 3D capable sailplane anywhere you want. The synergy of low weight and strong structure is very unusual in a production sailplane and can only be achieved with careful attention to design and construction. The details are outstanding, all seams are sealed, the covering is tight. This model comes with high quality European hardware and a fully illustrated instruction manual. This airplane is incredible stabile and predictable flyer, suitable for beginners as well as advanced pilots.

Absolutely unique, first ever, 3D electric sailplane. Slope, soar or fly 3D aerobatic routine with this machine.
