Testimonial from Uli Schwenk
„You can feel the passion and the sensitivity of the Jonker brothers.“
At first I want to thank Laurens Goudriaan for inviting me and organizing a glider for me to fly at the Qualifying Sailplane Grand Prix at Worcester, Western Cape, South Africa.
This was an opportunity to visit a gliding site that I had heard so much about but had not visited before. Now I know why the pilots have talked about Worcester so enthusiastically – I am also now enthralled by this venue and the amazing and fantastic flying conditions.
I feel very honoured and indebted to Attie Jonker who so very kindly allowed me to fly his glider AJ. On New Year’s Day together with Laurens we had a training flight when we flew 400 km. at a speed of 180 kph. It was incredible.
I had never flown in a JS glider before, so the first flight was my first introduction to the Jonker Brothers’ JS glider and it was a wonderful flight – I was totally at ease and comfortable and it felt so easy to do a flight at a speed of 180 kph – it was as if the glider was made for me and that it ‘talked’ to me.
Despite flying at high speeds I could still feel the air and whether the lift was off to the left or right – it was so easy and the glider was totally in harmony. Also when flying at high speeds the cockpit noise was minimal
and talking on the radio was excellent and not problematic, and the ventilation in the cockpit was extremely quiet and yet very effective. The wing profile is so good and this meant that the flaps do not need to be used so often and it was so comfortable to fly. It was a real pleasure and a joy to fly in all conditions and at all speeds.
I felt very safe in the JS1b 18evo
The workmanship is very professional. You can feel the passion and the sensitivity of the Jonker brothers and their team, that they have incorporated into their designs when you fly with this glider. It has been my incredible and utmost pleasure – thank you for this incredible opportunity, Attie – it has been amazing.

Die JS1 ist einfach eine dieser Konstruktionen, die man unbedingt geflogen haben muss. Dieses Sportgerät erfüllt für mich die Aspekte eines echten „Schiffes“ gepaart mit einer hohen Agilität. Einfach ein toller Fluggenuss.

Man setzt sich rein und fühlt sich wohl. Das Gleiten fühlt sind gar nicht mehr an wie mit einem Segelflugzeug und das Kurbeln bringt einfach nur Bock. Fühlt sich einfach toll an!

Dieses Flugzeug ist für hohe Geschwindigkeiten gebaut. Ohne Anstrengung und mit konservativem Flugstil waren hier 134 Km/h drin. Tagessieg.

Der Jetantrieb überzeugt mich ohne Einschränkung. Er ist sicherer als herkömmliche Systeme. Er ist kräftig und hat ausreichend Kraftstoff (Diesel) für 100 bis 200 Kilometer je nach Nutzungsweise an Bord.

The JS1 soon showed its impressive potential, consistently pulling away from comparable gliders as we carried out long glides throughout the speed range in good soaring conditions.
