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.
