THE TELLIPSOAR is a high-performance, Standard Class RC sailplane that is rugged and gentle enough for the beginner. It was not an overnight dream, but was developed over a period of seven years. The original design was called the Ellipsoar and was published in Sailplane in 1970. The name came from the wing and stab design. The wing and stab were elliptical in planform, and the wing had elliptical dihedral. In 1969 the elliptical dihedral was very rare, but several years later Hobie Alter realized the performance advantages and incorporated elliptical dihedral in the Hobie Hawk.
