We chose to reproduce the magnificent South African glider of JONKER company for next seasons GPS triangle sailplane competitions.
The aerodynamic design was entrusted to Franck Aguerre, a talented aeronautical engineer and well known modeler. For this formula 1 of the air, he specially designed a very thin wing airfoil (8% thick), the FAD22.
The fantastic wing has an exclusive system of adaptive twisting. The twist of the wing of the JS1 evolves according to loads apply to the wings, with the effect to twist (negative twist) the wing tip at High-G maneuvers. As a result, in conjunction with the aerodynamic choices made on this wing, a gain in efficiency in tight turns and better locking of course in roll and yaw during this type of maneuver.
The massive use of carbon and kevlar for the construction of the airframe, the latest technology and the know-how of the manufacturer provides an empty weight, ready to fly, truly amazing for a scale sailplane of 7 meters wingspan of... 13kg!
Of course, and to stick to the rules (wing Max load 115g/dm²), the water-ballast located both in the fuselage and the wings allow to raise up the weight to 15.65kg to turn the triangles on top speed when the weather is convenient!
