I just got introduced to this stuff, and it is tough as freakin' nails. Has anyone started using it in lieu of good old 5 and 15 minute epoxy for airframe construction? Seems to be about the same weight as epoxy, but I don't know if it's strong enough to stand up to rigorous aerobatics. Sure is easier to use, though, since no mixing is required. Opinions?

Works great for CA hinges, especially if you have to re-hinge as it expands.

Here is my experience with the stuff. I scratch build most of my aircraft so weight and strength are two considerations. For sheeting foam wing cores this stuff is amazing. Just remember to put it on THIN. Pull the glue out until there is just a sheen to the foam, LIGHTLY wet the balsa skin and tape it down. More glue is not better! This stuff expands and I mean expands as it dries. I have used it for Robart hinges, once again doesn't take much, just be sure to oil the hinge pin and watch the glue for overflow to the hinge. Just wipe it off before it sets up. For planking a fuse, very thin coat to the edges of the planking with some ca to hold things in place, gives a strong easily sanded finish. Play around with the stuff. Just remember it expands, more is not better, it likes a little moisture so set.

I use it all the time. Very rarely use epoxy anymore.
It works perfect for joining ARF wing halves too.

If you are using it next to covering line the edges with masking tape. The foam will pop right off.

Kinda funny ... I fly with a guy who uses this stuff for everything. Which is exactly why I've been turned off to it. The problem is this stuff seems to expand to great proportions. My friend's repair jobs all have globs of Gorillia Glue everywhere. The stuff looks as though its been extruded from his repaired joints. Nasty ...

For now, I'm sticking with Epoxy.

From the sounds of other posts, if its managed properly, its a good medium.

Use it on Epp, Depron, Aluminum, Styrene, and Wood. Or a combination of all the formentioned items. Great for repairs where a few beads or slivers were lost, by filling the small voids. But I usually fly aircraft less than 20 oz and strictly electric! I started with the Gorilla Glue but now use the Sumo instead, because it foams less and dries clear/white-hued ocassionally.

There was/is a new glue called "SUMO" that was suppose to be better than Gorilla -- never tried it but it was not suppose to expand as much. Anyone used it?

Gorilla glue is amazing, but use it sparingly, and clamp the joint. I use it in many places.

Yea......why did you use four times as much glue as you need?

Insanemoondoggie

I have to say , thats glued really good !

If you're going to use this stuff stay away from the high priced "Gorilla Glue" and buy PROBOND POLYURETHANE GLUE from Elmer's. Exact same stuff at 1/10 the price. Buy it at any hardware store.

Gorilla glue seems very popular but it seems to me that a glue that expands would be the last type of glue you'd want to use. Doesn't this characteristic cause problems when framing?

exactly, when used properly you cant beat the bond of gorrilla glue.

MasterAlex

I am falling on the floor ... you must know my flying buddy! That's not far from what his repair jobs look like!

ok,,sounds great but what about some specifics. like how long to set up and cure. how much does it wieght compared to epoxy. and last how hard is it to sand. Thanks

Here is the story.
A buddy of mine owned a hobby shop and was closing his doors. Obviously he calls someone with a truck. One of the things he had was a Lanier Predator. I didn't know he had it and he just gave it to me without a second thought. He told me he thought there was something wrong with it but couldn't remember. It sat around in my shop for at least 9 months before I even opened it to see what I had scored. When I was messing around I found what was wrong...the wing was kinda wiggely. Being a high performance plane I thought I better check more thoroughly. The wing was totally busted with the cover being all that held it togeather.
I toyed with buying a new wing or even making one then had the stroke of brilliance to give it a try. All I had to loose was some glue, balsa, and carbon tow. Like I said it was two pc and all kinda fractured. I stripped back some balsa and cut some new pieces for a patch, gave everything a healthy spritz with water put the glue to it along with some carbon tow under the balsa, taped it up and clamped everything togeather. You saw the pic of what I woke up to in the morning. The unibrain!

I let it set for a week or two cause honestly I was a bit intimidated by how much sanding it would need and thought it would most likely have a horrible twist to boot. After a night of drin...er...thinking about how to tackle it I just did the grip and rip as mentioned earlier. To my surprise all of that came from a small gap in the balsa patch! The big glob popped right off and I had it all sanded ready to cover in less than an hour.

I have been flying the plane for over a year now with a Jett .50 and not a second of worry about failure.

I am a gorrilla glue believer!!!

Buy the small bottle. You most likely will not use the honkin big one before the bottom third goes bad. I learned that after it happened twice. Probond is fine too. I have used both.

Cool story , thanks for sharing. I really like the way you can sand/tool it.

Here are some pics of the clamping. Ol Rube would've been proud.

And the finished product. The first engine I had on the plane was a TT.46 till it sucked the bearing cage[:@]

The plane is awsome.

Gorilla glue is great if used correctly.

I only use gorilla glue if I can check on it every 5 or 10 minutes for the next couple of hours. That way if it foams a little to much you can catch it.

Its great for wing joiners and other areas where the foaming really locks it in place. I use titebond and gorialla glue probably 90% of the time. I use epoxy less and less not (mainly for fillets or to put down fiberglass cloth)
