Yeah. It's just gorilla glue brand 5 minute epoxy.
Keep in mind like most epoxies what 5 minute means 5 minutes working time before it's too hard to use. Almost every available epoxies I've come across require 24 hours for full bond strength regardless of its stated working time.
It is VERY important that you do your best to mix equal parts together and that its mixed really well. You should ALWAYS mix more than you think you need so theres plenty to work with.
What I do is mix the equal parts on photo paper as it's nice and stiff with something small enough that it mixes well and you dont end up with a glob of one part and not enough of another. Sometimes I use a toothpick if it's a small amount and go up from there into maybe the end of a cheap small painters brush (like you would paint a picture with) as I like to be able to roll the stick over to help it mix. The other trick I use to really mix well is I buy those boxes of regular razor blades from harbor freight. After I do maybe a 30 second mix with a stick I take the razor blade and scrape the glue over itself over and over for maybe 1-1.5 minutes longer so I know it's super mixed. All I can say is you get a feel for how long to mix compared to how well you need it to flow and I'm not sure how to explain it any better. The bottom line is bec as use its 5 minute epoxy you dont have a lot of time to mess around as once it starts to harden quick if you dont have it where you want it it loses its holding strength. You want to get it where you want it while it still can spread easily or you really are going to struggle with it and it's just not going to hold anywhere near as well as it could. It sure would be great if I was there to help. It's not like it's hard to do. I just want you to succeed.
So depending on where you need to get the glue sometimes you can use a toothpick to get it there and sometimes it's just easier/better to use a finger. You could wear a thin rubber glove but to be honest it's easier without one. Of course you tend to leave your fingerprint though without one
Again, you must toughen up the area the glue is going to touch as the surface area you create by doing so adds a tremendous amount of strength compared to a smooth surface. To be honest all I usually do is take a razor blade and scrape up the area both on the flat and right on the sharp edge to create a bunch of different edges for the glue to grab. Try scraping or cutting in shallow gouges in all directions as the rougher the better.
You should be able to find that glue practically anywhere from a grocery store to hardware to home stores and any place like a walmart/target etc. I'm betting almost every car parts store has it too. Gorilla glues and tapes are extremely popular.
This reminds me that anyone who regularly uses epoxy and tapes like duct should watch the tests between different brands on youtube. It's amazing how good/bad some are at certain things and not others. It's not like the stuff is super cheap so why not buy what works best for your application.
So as far as the strength required for what you need it to do, fortunately the breeze isnt very heavy and I personally believe if i had it i could easily make it strong enough to not be a concern. By taking a few more pics I'm really hoping your repair will give you enough confidence in it that you wont be really edgy about flying it at its limit.
What I do with ALL my repairs or lighting additions is test them out maybe 4-6 feet in the air whacking the controls all over the place to attempt to shake it apart. I havent had any issue with my repairs/mods as I'm a bit paranoid of potentially hurting someone so i overdo it. I would rather carry around a couple extra grams than take the chance of having it fall out of the sky.
OK, time to mess with a parabolic antenna booster build I've wanted to try. I'll check my messages from time to time.
