The maiden flight of any new product is such an amazing and exciting occasion. Imagine the rewarding feeling if everybody involved can be in the cockpit for that first take off… that ultimate moment for the design team. It was a bold step, but JS evaluated the risks and decided that the time was right
The JS2 Revenant, a high-performance, versatile, easy-to-fly self launcher! The name Revenant was inspired from the French verb Revenir, meaning “to return”. The JS1-C is now making a return with an amazing powerful self-launching system! Only 4 hours to go before our LIVE virtual “walk around” 15h30 UTC!See you there!!
Excitement is building as the JS2 Revenant nears completion….The R&D team developed and constructed the prototype in our new state-of-the art R&D facilities. Join us on Facebook this afternoon (Friday 26 March) at 15h30 UTC (16h30 Central European time) for a LIVE virtual “walk around” the JS2. Whatever you do, don’t miss this! Stay tuned…….
Despite the threat of Covid, South African and various overseas pilots were keen to compete in our annual national gliding competition. It was not until the eleventh hour, that the international Covid-challenges were trumped, and six international visitors made their way to Welkom. South African December holidays in the Highveld are typically associated with warmth,
The JS design team was thrilled when Idaflieg approached them to test the JS3’s performance during their 2020 Summer camp. Oftentimes, a manufacturer would be nervous at the idea that their glider’s published performance data may come up for scrutinizing and may even refuse to approve such a request at all, yet we see
Although South Africa (SA) is currently ranked amongst the top in the world regarding Covid-19 active cases, we are very grateful to report that the effects of the virus have not affected employees of Jonker Sailplanes. JS has taken all the necessary steps to ensure reduced risk of infection under employees, and not one Covid
Our chief design engineer did not want to give any performance away with the JS2 fuselage. In fact, he designed the fuselage with even less drag than the JS1C fuselage. Obviously, this raised some concerns to our marketing team if we would be able to fit our better built customers. As soon as the seat
Opening the molds for the first time it is like opening a treasure box. You expect something amazing – the result of years of design and many weeks of construction, revealing its BEAUTY. It is an amazing feeling for everyone involved seeing the real product matching the expectation the CAD models promised.
This week we saw a giant leap towards the completion of the REVENANT. After many weeks of accurately positioning components in the fuselage, verifying computer models and making small design changes, the JS2 fuselage was ready to be closed.JS spend a huge amount of engineering time to construct highly accurate tooling – this to ensure

The latest issue of the gliding magazine SEGELFLIEGEN has just been dispatched to shops in Germany and Austria. This issue covers the 2020 Helli Lasch Challenge in the 5-star game lodge TSWALU, South Africa where some of the world’s top glider pilots enjoyed a week of luxury gliding.

For those who missed the link in our latest newsletter, here is a copy of the article… Weight and balance is such a critical flight safety component – so often neglected by many of us aviators. Just imagine that the complete weight of an aircraft in flight is carefully balanced somewhere around the main wings,
The image shows a flow field around a wing tip without a #winglet. More precisely, it shows the extent of positive inflow angles at the tip region. The addition of a winglet would utilize this flow field and increase performance, only if it is inside the boundary of positive inflow angles. At higher flight speeds, the
