I used to build a lot of indoor foamie airplanes, especially for other people. This was extremely popular. I like it a lot.  But,  epoxy works just fine. This glue is flexible, where epoxy is not.

Epoxy tends to be heavy, and way stronger than it needs to be to get the job done -- but it does work.

Depending on the job at hand:

GG (Gorilla Glue) the white stuff works very well. Most combat builders use it on foam to anything else.

Yeah I buy it at hobby people. But I belive hobby town usa carries it.
Also, like Tim and Ken said, the white gorilla glue is awesome. I forgot about that one

Depending on the job at hand:

  • epoxy with lots of microballoons mixed in
  • Canopy glue (like "RC56" -- names often have "56" or "560" in them)
  • foam-safe CA
  • "low temperature" hot glue -- it's heavy unless you really control the film thickness, but it's fast and effective
  • My favorite for crash repair on Phil Cartier-style foam wings is Gorilla Glue.  Follow the directions on the package -- it needs water to kick it off.  If you need to fill a big void, squirt some on a card and mix in a bit of water, then pour it in the hole.

I broke my cheap float

Gorilla glue.  If that doesn't last, rebuild the mount with a 1/8" thick plywood plate that's about twice as wide and twice as long.

For that, I too nominate Gorilla Glue. Its all I use on foam and a lot of wood now too.
