will never know will we? Here is a CFD on a P51. Would you put a

Paul, is it available to show the bottom of this P51 in CFD.
CFD would clear up a lot confusion for all our varitiy of aircraft if

it is

available for all the various configurations.

That is about the only one I have. I might have an RV around here
someplace.
Wait a minute here are some on a twin pusher and an RV6.

Note also on the RV the high pressure on top of the fuselage toward the
back of the empennage.

Al

There is a vertical tail sticking up that adds to the pressure. The opposite of
a pusher with a sucking fan.
