Hi Paul and group,

An engineer, from Texas related to the NexusMustang Yahoo groop, has
sent me this link.  It is not related to rotary engine.  But I would
like to share this link with all of you.

That has been around for years. Airfoils are VERY VERY easy to test
for lift to drag ratio performance. If it was any good Boeing would
be using it.

Where are the lift to drag ratio curves? The web site is all BS.
A waste of your time.

Buy this cheap book and you will know as much as anyone knows about wings.
