On the 12th December 2016, the 10 years maiden flight anniversary of the JS1 was celebrated with the first test flight of the JS3 Rapture.
Five years of intense CFD work done by the company's chief aerodynamicist Dr Johan Bosman, resulted in this revolutionary new model. Jonker Sailplanes' design philosophy with the JS3 was to create the ultimate competition glider for highest performance in weather conditions ranging from weak survival weather to the strongest desert conditions, without compromising feel and handling ability.
The JS3 is currently the 15 meter glider with the highest wing loading on the market, but with an exceptional ability to carry this load, while retaining the feel of a light glider.
The JS3-15 was introduced to the world at the 34th World Gliding Championships in Australia achieving 2 day wins and the fastest task speed in the competition.
The JS3-15 can be ordered with interchangeable 18m wingtips.  See JS3-18 for details.
