"Heavy Lifter" Foamy? My next project.

When I'm out photograhing airliners, it always amazes me when I watch those huge wings flex and lift the airplane into the air and then "relax" upon landing. After thinking about that for a bit, I've decided I want to have some fun with my depron sitting around and see just how much cargo I could carry in a foamy. I want the wings to be just strong enough so that you can see them "come to life" just as I lift off with a heavy load and then relax again once the wheels are on the ground.

I will give it flaps and operation bomb doors just in case I'm looking for some extra fun.

Right now the fuselage is a 40" long "triangle" obtained by scoring a sheet of 9mm depron into thirds and folding. The flat portion of the triangle will be the top so that I can put my micro video recorders on board the aircraft with a very thin plastic window. I figured this shape will produce perhaps a bit more (at least not a lot less) lift and is nice and strong.

The big delema right now is coming up with a planform for the wings. I think I will just copy the basic planform of a full scale heavy lifter and start from there.

As soon as I get something actually worth photographing, I'll have some pics up.

Sounds like a cool idea!!!
You would have to have some type of airfoil on the wings to be able to produce any lift unless your using motor/batteries of insane proportions to pull all that weight through the air on a flat depron wing Thats the only way that those big heavy lifters are able to even get off the ground is with a nice efficient airfoil. I'm interested to see what you come up with! Shaping an airfoiled wing out of depron is a bit tricky,
good luck! subscribed

Yah, don't use a flat plate airfoil, they are only good with light wing loadings. You can build an airfoiled depron wing and also add flaps for extra lift. There are quite a few threads on RC Groups of building airfoiled, hollow, depron wings.
