OK Leo L-B, time to step in; curious minds have questions.

Like many, I've been following the Jonker JS1 18-21 self launcher webpage found here http://www.js1.co.za/js2selflaun.htm . First thing I noticed was JS2 in the URL. So after awing over all the pictures (I love that kind of stuff) curiosity set in. Why would Jonker go to the expense and trouble of designing a new fuselage for the SL when the current JS1 fuselage was a "knock-off" of an outstanding self launch fuselage being the ASH-26? And, why would they show a new wing mold when there isn't an announced wing change to the 18-21 EVO? Obviously, they get only so many "pulls" off a mold before it has to be replaced but it came across as a "something different" mold.

The recent SA FAI SGP YouTube broadcasts got my attention when the JS3 was mentioned...news to me. Even more surprised to learn Jonker discussed it at 2016 Nephi and that "scoop" didn't make it to R.A.S.

What does make since...at least to me...is the pictures on the above self launching site are actually the JS3 which I understand will have a 15-18 wing and not a 13.5-15 wing that has also been mentioned. New fuselage and wing molds certainly make sense here.

Shaking my head in disbelief that I'm agreeing with Sean, I think the Jonker brothers have taken the lead in current competition sailplane design. Great job Team Jonker.
