I guess it had to happen eventually. I flew my E-flite Apprentice 15e in winds that were a little too strong yesterday evening and flew it head-on into a light pole. I got off pretty easy, I think. I'm going to need a new motor mount, cowling, and wing. I've removed the servos and hardware from what's left of the old wing and noticed that they are held in by some sort of white adhesive that is fairly soft. I need to get the old stuff off and then will need to buy some to put the servos into the new wing. Can anyone tell me what this stuff is?

Thanks,

It's hard to be sure but I'd say its a polyurethane type glue. I think one type is called gorilla glue. I've never used it in modelling but I know people do and it's very good stuff and doesn't dissolve foam like a solvent based glue would. Whether it sets soft, like you described, or not depends on the glue specification. Some polyurethane glues will set pretty dense. Others can form a lot or air bubbles and so the glue expands as it cures. The extreme of this being expanding foam which is also a type of polyurethane.

I guess tree is one of the right formula for modelling. I don't fly foam so I just use wood glue and the ever helpful CA (superglue ).

Im pretty sure that's a silicone based caulk type glue. (it's NOT Gorilla glue )
(it should come off with 'Goo Gone' or regular old lighter fluid... they SHOULDN'T eat the foam, but test first. )

Lately I've been using Beacon Foam Tac glue with great results.
it doesn't matter what type foam either, pretty good stuff.

Thanks for the tips. I've used Gorilla Glue in my shop but thought it was basically a wood glue. Apparently there's more than one type. I'll have to look up Beacon Foam Tac. Again, thanks!

The WHITE gorilla glue is really good for foam repairs. But here is a tip on fixin' foam crashes.
If you have compression in the foam AKA "smooshed foam" remove all the electric gear and pour HOT water from a tea kettle over the SMOOSHED area SLOWLY. It will expand to close to new. As it was molded each little cell is flat on the outer surface but now will have a bump to it. Iron these bumps with a COLD can of your favorite beer or pop RIGHT after the hot water. Now you can use your favorite glue to re-attach the parts. Clear packing tape over gorilla glue seams helps keep parts aligned and control the OOZE. Don't try to fiddle with the ooze till its set though.

Always pick up every little scrap of crash debris balsa or foam or whatever. Keeps the landowner happy AND if you decide to REKIT the pieces are there. Foam crashes are just as rebuildable as balsa....snow storm crashes excepted!

Tip keep your trash bag in the fuse so it handy at the crashsite...I know that's an OLD joke but it fit here!

Thanks for the great tip! I think you just saved me from having to buy a new stabilizer and rudder.

Me personal i would not use the gorila glue. I have descovered a type of glue that holds as strong as epoxy but is better. This glue is call fabritac. It is a ten dollar bottle, but i think it is the best.it doesnt dry like epoxy or most glue. It comes out of the bottle real thick and dries like cocking. It is a rubber type of glue that will give that little bit of flex where other glues dont

Stormrider is definitely in the running for the Busted Prop award this month.

Hey, I've only had to replace ONE prop! It's motor mounts I've been hard on.
