So we are thinking the JS2 will be the 20m 2 seat flapped glider to rival the Arcus?

I'm taking a big guess here, but isnt the JS2 their new self launcher ? Not yet released as far as I know.. No, sorry the new self launcher is called the JS1 Self Launcher not the JS2 :oops: <http://www.avcom.co.za/phpBB3/images/smilies/icon_redface.gif> Maybe the JS2 is still a secret.. --------------------------- Which is what the Jonker website calls the JS self launcher --- JS 1 self launch. The link may be tagged JS2 but they clearly call it a JS 1 self launcher Mike At 09:36 AM 12/13/2016, you wrote: JS2 seems to have become the JS1 self launcher, they give it away in their early promo material / website URL's I.e. http://www.jonkersailplanes.co.za/js2selflaun.htm On Tue, Dec 13, 2016 at 9:44 AM, Mike Borgelt < [email protected] <mailto:[email protected]> > wrote: Thanks Richard, Here's another link to another image. http://www.avcom.co.za/phpBB3/viewtopic.php?t=183997 Interesting. Note high location of wing and obvious section change near the root with drooped leading edge for better alignment with alpha flow. Retractable tailwheel. Note also locations of pitot static and TE probes on the tips of the tailplane. Not bad guys. The probes can be a lot shorter (should be a local chord ahead of the surface to prevent interference), the flow at the tip shouldn't be affected much and moving the probes there prevents the disruption of laminar flow over a substantial part of the fin. Other than that it looks like a scaled down JS 1 wing. Wanna bet that this will be a 15/18M glider? I can't see a huge market for a dedicated 15m competition glider nowadays but a 15/18M should sell well. The JS1 seems optimised for 18/21M. So what happened to the JS2? I'd say it is a JS1 with the JS3 tech incorporated. Mike At 08:05 AM 12/13/2016, you wrote: Just in case anyone missed it, Jonkers flew a 15m prototype. No word yet on whether it will be at Benalla or not. http://www.jonkersailplanes.de/js3-the-second-one/ Rich. _______________________________________________ Aus-soaring mailing list [email protected] http://lists.base64.com.au/listinfo/aus-soaring Borgelt Instruments - design & manufacture of quality soaring instrumentation since 1978 www.borgeltinstruments.com <http://www.borgeltinstruments.com/> tel:  07 4635 5784     overseas: int+61-7-4635 5784 mob: 042835 5784                : int+61-42835 5784 P O Box 4607, Toowoomba East, QLD 4350, Australia _______________________________________________ Aus-soaring mailing list [email protected] http://lists.base64.com.au/listinfo/aus-soaring _______________________________________________ Aus-soaring mailing list [email protected] http://lists.base64.com.au/listinfo/aus-soaring Borgelt Instruments - design & manufacture of quality soaring instrumentation since 1978 www.borgeltinstruments.com <http://www.borgeltinstruments.com/> tel: 07 4635 5784 overseas: int+61-7-4635 5784 mob: 042835 5784 : int+61-42835 5784 P O Box 4607, Toowoomba East, QLD 4350, Australia
