For all you non-believers and skeptics that did not believe the JS1 had
been measured by the Idafleig at 63:1 please see the latest posting on the

Jonkers website regarding the JS2. Your really not as smart as you think
you
are.
How odd the 63:1 only occurs at the high wing loading in 21M, and not at the minimum wing
loading, where the L/D is essentially the same for the 18M and 21M wings.

I noticed the same thing. So there is essentially no reason to fly it in 21m dry configuration? And almost no situation where you would fly it dry in either configuration anyway?
