Default Southern's Sorghum

I've used it for more than 20 years for sheeting foam wings. It works great. It was originally sold by Southern R/C here in Pensacola, FL. It's basically just liquid latex rubber, but I've sheeted a number of wings and never had a problem with it. I tried the epoxy method of sheeting about 10 years ago, but went back to Sorghum! Also used it for many other things, like sticking sandpaper on discs, etc...

I don't sheet foam wings very often, I prefer the built up type, but I did sheet a wing for a 30% Extra 230 with Southern Sorghum and it worked just fine. I still have the wing several years later and the sheeting is still just fine, never came loose.

Default SOUTHERN SORGHUM

Used that stuff many moons ago. I think the urathane glue like Elmers Pro-Bond has come into being a very popular method of bonding skins. At least for me it has. It penetrates the foam with a foaming action and is much lighter then the latex glues. Now you can make any wing heavy if you spread enough glue on it, but when done properly you can achieve excellent results. since its a one part glue it is much, much easier to use then epoxy.

Use what ever floats your boat and if Sorgham works for you then have at it. The urethane also cures harder then latex which stays somewhat plyable even after cured. So I can only think that urathane makes a stronger wing by increaseing the compression quality of the bond bewtween balsa and foam.
