Nice work, Jonker Sailplanes Team! You can see the smile of PURE PRIDE in workmanship in that ship as he helped get it to the line. These expensive ships provide jobs that give people something to be proud to be a part of - and produce things that bring others joy in ownership. I hope to one day join the ranks of JS owners. It looks like a wonderful Team you have gathered together. Good luck, blessings and peaceful soaring at Uvalde and beyond.
@@Ljet600 You've got it the wrong way round. Glider pilots want to get rid of any small drag they can, to the point that many competition gliders have bug wipers to get rid of the tiny drag created by dead bugs on the wings. On the other hand, extra weight can be an advantage, as the best gliding speed for a heavier glider is higher than a lighter glider, so the heavier one will be faster between thermals.
Very impressive, outright. One question, however. Did you increase the flutter testing with a 20 km/h step? Calculations, for instance with NASTRAN show that above a certains speed the damping very fast reduces an becomes negative. The FAA advises hence to step up with 4 kts (7 km/h) steps for each increase in speed. By taking larger steps you could pass unintensionally the critical damping area, and enter the danger zone.
I believe, that the absolutely key has to be, to built a complete new wing profile. Wind resistance by 250 km/h with glide ratio of 1:80 should be similar to a pinguine body. This ones swim enormous fast with a huge water resistance. That means their shape is absolutely optimized. Dolphin also. How reachable? Look at the front nose/body profile.

Jonker Gents , AP & Uys, Please allow us to come and do Celebrity-Drive or perhaps a Celebrity Fly interview at your most convenient opportunity. We are based in the Cape, so if you guys can give us some time, we will make our way there! Looking to experience the "JET" power glider!
Wow that's a beautiful glider! Thanks for a great video and to all who were involved in designing, building and bringing this amazing state of the art bird to fruition. Its awesome!
Very nice and usable, but that power knob may be much more responsive, isn´t much safe to rotace this knob too much times to get full throttle. It may need only 1 or 2 rotation, because isn´t necessary to have it so sensitive.
