The center of lift would change every time you moved the flaps/LE slats. Those flaps dont just go down they extend and make like 20% more wing area in the back, so there would be a huge change in the center of lift. Its amazing all the computer work done while loading the full scale. still and awesome plane, and very scale.

Unless he is going for total scale realism, internal structure and all, then I would agree that the model wouldn't stand a chance of flying, but then, whats the point for such a giant model?

But just because the full size 747 has fuel in the wings doesn't mean that is the best place to put the fuel in the model that is supposed to fly. Swept or not, finding the CG of a wing involes the same procedure.

well...here's a picture of a different angle from the same site...guess it DOES fly...

Really Good One

It looks like it doesn't use flaps/slats on the takeoff roll either, heh.

There's a video of a similarly sized Air France jet on AugustoHeli.com near the bottom of the miscellaneous section. It flies, as evidenced by the video. There's no reason to think that this model wouldn't do the same.

FYI, the guy who built the 747 used a similar airfoil from his large Airbus.

Wes;
I don't think thats rc, if you were to take a 747 and scale it down into an rc plane it wouldn't fly. There is no way you could ever get it going fast enough.
Using the same reasoning, there are plenty of P-51 Mustangs, P-40 Warhawks, Spitfires, DC-3's, F-16's, F-14's, F18's, B-17's, Bell UH-1's, Bell 47G's, Hughes 500's, BK-105 and 117 helis, Bell 212's, Extras, Lasers, Pitts Specials, C-130's, Stearman Bipes, .... that can't be RC or fly out there. Maybe someone should tell Vario to close up their scale heli shop, too. I guess my 1/5 scale Cessna 182 Skylane doesn't fly either.

Come to think of it, there are a lot of kits in the latest "Tower Talk" sales flyer that meet your stated criteria -- but a lot of people seem to buy them anyway.

Go to the "Photo Gallery" at http://www.amtjets.com to see more scale, turbine powered, RC aircraft that really, really do fly.

By the way, when NASA was thinking about putting the Space Shuttle on the back of a 747 so they could ferry it from Edwards AFB back to Cape Canaveral, Florida -- the whole kit and kaboodle was scale RC modeled and flown as a test bed.
