formance but not for contests. The world is awash with very cheap used gliders right now which offer 80% + the performance of new ones so a kit of that performance is going to fail. Mike Borgelt Instruments - design & manufacture of quality soaring instrumentation since 1978 www.borgel

Re: [Aus-soaring] JS3s arr Benalla

Ian, In the "good old days" the regulator would most likely not have allowed the JS3 s to fly as they weren't fully certified aircraft. There was a glider called the FK3 https://en.wikipedia.org/wiki/VFW-Fokker_FK-3 and here http://www.fk-servicecenter.com/navid.17.dblid.12/fk3-1968-otto-fu

The actual video is 15 minutes, in case you think you don't have a spare half hour. Glider seems to be quite Schleicher like. Fuselage shape reminiscent of ASW20. Mike At 08:35 PM 1/1/2017, you wrote: New video up from GFA about the JS3. Uys goes into a very long discussion on all the de

Re: [Aus-soaring] JS3s arr Benalla

The tips are the JS1/18 Evo tips. I guess the 21M JS1 tips will fit, making the new JS3 18M glider. Someone may like to try that as there are 21M JS1's at Benalla :-) Aspect ratio would be 32.86 by my calculation. Higher than most 18M gliders by 10% or more. Only 18M glider like that at present

One more thing: by splitting the wing at that point the inner panels are mercifully lighter at 60 Kg. Mike At 08:31 AM 1/2/2017, you wrote: The tips are the JS1/18 Evo tips. I guess the 21M JS1 tips will fit, making the new JS3 18M glider. Someone may like to try that as there are 21M JS1's

Re: [Aus-soaring] JS1 at Benalla

Interesting how the Ventus 2 in 15M is the glider of choice and the ASW27/18 in 18M class. Yet the 18M Ventus 2 and 15M ASW27 aren't chosen in those classes. They are after all nearly aerodynamically identical with just a wingtip stretch to go to 18M. Superstition? Mike At 11:17 AM 1/6/2
