When I click on the link, it opens a window and then immediately opens Windows Media Player and the video runs.

This model set is quite an accomplishment.

That guy is real good.

Gorgeous!

Guess it is supposed to be recreation of Yeager flight of X-1. Also think that Model is not the $21.94 Father's day special at WallyWorld.

Jetdrvr,
Thanks for sharing that. I'm sure impressed! Would one of you pilot-types out there please explain how a plane can fly that long upside down? It seems to me that the lift would force the craft down. Can it be countered with the control surfaces?

Here is another one of a B52 that is quite impressive.

I can't imagine putting all that work into that B52 and having it go down like that. What a heartbreaker.

Hmm, yes, so you doubt the basic theory of flight? You have noticed the obvious, where as most pilots ignore what they see.

The thing is that a plane with an upside down fuel and oil system can fly upside down indefinatly. When designed to do so especially they will do it just as well as upright.

How they do it,I think is obviously the same either way up. IE If needed for lift, have the leading edge up a few degrees into the relative air-flow. This should insure the air-flow leaves the trailing edge moving downwards which will "push" the wing up, as an equal and opposite action/reaction.

When not designed to fly efficiently upside down, things are not so easy. You then need more angle of attack for more lift (downwash).

The controls also then tend to run out of ability to hold the nose up etc.

Another amusement was being taught that diheadral was a big help in keeping the wings level. So when I was upside down, the instructor commented on how stable we were, and reckoned the air was getting trapped in near the fuselarge. I tell ya, they make these things up as they go along.

Turning when upside down was another slight confusion for a while. I had to lead with the rudder which was obvious to go left or right, and then cross controls to bank the wings the right way to suit.

My little semi-aerobatic plane's Max dive speed was limited by the engine's red line as it would wind up even with the throttle back past yer elbow.
What fun.

I always ignored a lot of what I saw, hoping that it would just go away...
