Super Floppy EPP


Gentlemen , we were given a big box of ~ 1/4” EPP sheets that is so soft and floppy , we’re trying to figure out what to make out of it … I guess i could brace it with skewers, or put tape over it ( stressed skin) , but it would be Nice to make something superlight out of it … You guys have any ideas ? We have about a dozen sheets of it … hate to see it go to waste …

Super floppy EPP would be good to use to skin a structure such as wing ribs or a built up fuse. 1/4" however is very thick. If you could put it over a built up balsa structure the weight may be reasonable.

John , I’m trying to retain the Elastic properties of the EPP ( for crashing purposes ) , but you did give me a great idea … use EPP ribs and spars inside .. we have some of the stiffer EPP too …That would work … Thanks !!!

I used it on this Turkey Vulture. More for esthetic purposes to give it a more realistic 3D look. Main box fuse is $ Store foam.

Spritz it with 3M77 (or ??) and double it up. That's what I did with my thin stuff to make it more adaptable and it worked like a charm.
