Glue recommendation

[runway14left]

I'm looking for recommendations on which glue would be best in this situation.

I need to glue wings onto a new fuselage. I hear people saying such good things about hobby tac, but in my experience, it hasn't seemed to hold all that strong. Would epoxy be better?

And if epoxy, are they all foam safe, or how do you know if they are foam safe?

The short answer is it depends. Which kit and do you have photos?

You got any more information on your particular application? On a model I will use different glues for different things. I use tacky glue to help hold screws in wood, loctite on metal to metal stuff, the supplied contact adhesive in the white tube that comes with freewing models for most other items on the plane, silicone to put on clear light covers or exhaust cones, and CA to help hold a carbon rod centered while I place the wings on.

If you have any extra material from the kit, test a piece. I would think epoxy with micro balloons or maybe milled glass might be better than clear epoxy. And rough up the surfaces before you glue. And don't glue over paint.

This application is EPO foam to EPO foam. and yes, paint will be removed before gluing.

Foam-Tac....

I always lightly score with an Exacto knife in a crosshatch pattern before gluing foam. Especially, if I'm using epoxy. I try to use E-6000 contact cement in most cases. Epoxy cures hard as a rock and makes it difficult and damaging to remove and replace a wing, stabilizer, etc. I only use epoxy in cases where extreme strength is needed. Knowing what glues are best for the situation mostly comes with experience, but we are here to help! Good luck! Doc

As Tired said, Foam-Tac is undoubtedly the top product but to throw another alternative that I also use extensively is Gorilla, the 1hr white(not the 2hr amber). I have snapped fuselages in half on 57" 7lb EPO warbirds and they are still flying because of the use of both of these glues.

FoamTac doesn't hold well if you don't do it correctly. If you just put it on and slap the 2 pieces together and leave it, that doesn't work so good. You have to put it together so the glue gets onto the other half. Then you yank it apart and let the air at it for 1/2 minute. Then put it together again and take it apart again, wait 1/2 minute. Repeat one or two more times until it gets very tacky to pull apart.
Also, it depends on how the wings go together. Are they 2 halves that get glued together in the middle, then get glued to the plane? Or are the 2 halves that get shoved into the sides of the plane? Is there a CF spar running through the wing halves? Just saying EPO to EPO doesn't tell the whole story.

Foam-Tac should always be used like a contact cement and let sit for several hours.

I think part of my problem is I bought HOBBY Tac. Its not FOAM tac.

Another vote for Foam Tac here.

I agree, Foam-Tac and Gorilla Glue are the way to go! All the planes in 'airplane triage' were repaired using these two glues and all are back in the air.

I was in this dilemma just a short time ago when I sheared off the landing gear on my Devil 3D. What should have been an easy fix turned into a nightmare. I used E6000 and it softened the surrounding foam so badly I had to cut out a large area of soft foam. Seriously, it spread like some disease. Anyway, my conclusion with E6000 is that it can be used but NOT for larger areas. Now what I'll promote is Gorilla Glue CLEAR. It's meant for foam, among other things. I tested it on two pieces of foam. It take 2 hours to set and 24 to cure so this isn't for quick fixes. The next day I stress tested the foam. I bent the piece until it broke and it broke in another area...not the glued area. I swear by this crap and now use nothing but.
