I a gorilla glue fan myself. Plenty of set time and it expands to fill in any gaps and I think forms a better hold on formers and ribs since it not only glues the top of the rib or former but as it expands it grabs around the edges too.
Plus you can glue about anything with it, it's non-toxic, non-acidic, 100% waterproof, heat resistant, and I could go on and on. I originally discovered it while looking at wooden homebuilt aircraft.
Plus it's sandable, paintable, and stainable so it's easy to work with after you've glued anything together with it.

The trick to it though is to use it extra sparingly since it expands 3-4 times (at least that) so if you glob it on well you'll have an extra strong joint lol. I like to apply it with a small foam brush just enough so you can tell it's on there, and then clamp the parts together. It's important to secure the parts together though otherwise as it expands it will actually try to push the parts away from each other (still hold them just not good when things need to be aligned perfectly). If you brush it on though it's not really a problem.

As well it seems to make a much stronger structure than CA, probably closer to something built with nothing but 30 min epoxy but without the weight of epoxy.

However when they say it's sandable it's not that sandable. It would be different on harder wood but with balsa you want to either mash down (it sort of foams up) or scrape off any overflow before it cures. Once it hardens it's like brick but doesn't gum up when you sand it unless it isn't dry. Like I said though if you put it on sparingly thats not really a problem.
