Gorilla glue has its strengths, but it makes me nervous thinking about using it for pin hinges.
Thirty minute (or longer) epoxy, on the other hand, is tried and true. Messy, but it does a great job.
Just thought I'd offer up my two cents worth.

Not trying to push this stuff. It's just an idea for those up for trying something new? I KNOW what it's like using epoxy to fasten hinges. I kept seeing notes on it's use here and other places online. It's proven effective, and fairly popular among those that have used it for this application. I tried it, liked it, so I thought I'd toss it out here for you guys to mull over. It does wipe up fairly easily prior to hardening.
Been building a long time, so I get how somebody that's been building a long time might be set in how things are done on their planes. On the other hand, I'm always on the hunt for tricks, processes, shortcuts, whatever, that let me build more efficiently? Stuff or processes that offers no downside, but might make building easier, faster, lighter, etc.?
Tom, not familiar with their white glue. This is the stuff I'm thinking of:

I have been using nothing but Gorilla glue on pin hinges for about four years now. There was a little bit of a learning curve at first. I practiced on some scrap wood. I swear by it as well and will never go back to using epoxy on hinges. I have had zero failures of any kind. You must learn how much to wet the wood and how much glue to use. If you use too much water if will foam like crazy and make a mess. I find the best time to clean around the hinge is about 15 minutes after installing. By then it has stopped foaming and is just getting rubbery. I twirl a Qtip over the exces glue and it lifts right off.

ahicks, two years ago we had a similar conversation.

Whatever glue I choose, it is still going to be some kind of process. I was looking at the DuBro packaging and they're suggesting CA. It all boils down to making sure the work is done to insure they are locked in. I'm appreciative of everybodies input. I got to get this project moved along. I spent the better part of the afternoon just getting the slots enlarged and cleaned out. It was nice to look over my shoulder and see the ailerons on the wing panels, ready for glue.

She's a beautiful lady, to be sure.
Whatever you do, I would NOT recommend CA for hinges, unless you're using CA hinges. Just remember, though; CA hinges = an expiration date for your plane.

It's too beautiful a plane to do something so slapdash. Take the time and effort to epoxy in Robart Pin Hinges. This plane deserves to live for many years. It is perhaps my greatest treasure, at least of my RC world.

Most people, me included, have had problems with the CA hinges on this plane if a gas engine is used. I don't think it matters what type of glue is used to install them. They will crack eventually, even the blue ones for giant scale birds. If you look at the video of the vibration on the tail of this plane, you will understand why it needs some tough hinges and pushrods. I went to hinge points and have not had any trouble in over 3,300 15 min flights.

I do get a thrill, just looking at it. Had to get that photo of the first time with the wing in it. Also, it's so large you kind of have to get use to just handling and moving it around. It's different compared to smaller models. Hopefully this weekend will allow me to push it another few steps.

Do you fly at the Fox Valley field over by Elburn?

It is quite a plane. Moving it with the gear mounted it on the wing got to me after a few trips to the field, it was just clumsy to load and handle. I bit the bullet and mounted the gear on the fuselage and now I would never even consider mounting the gear on the wing again.

The Fox Valley Aero Club is in St. Charles, just west of me. I'm not a member, there is membership Assesment Fee of $300, with a yearly membership of $125. Too expensive for me. I do fly at the DuPage County flying field, that only costs $35 for the yearly permit.
Interesting that you mentioned Elburn. My girlfriend and I ride motorcyles. We ride out to Elburn frequently, weather permitting. There is wonderful meat store, http://elburnmarket.com/ They are an award winning, high quality, meat store. A ride out to Reams Elburn Market is always a pleasant one.

I know that meat market well, they do a lot of business for a small place. Have some in-laws in Elburn, so we get to shop there a lot.
I have flown at Fox Valley as a guest a few times. Always feel like I should wear a Tux and shine my shoes when I go there.
Our fees at GSWAM are $100 a year, so I'm used to fairly high prices. We have a grass field, so I don't feel like I need to put on my Sunday best to go flying.

A LOT of guys rip their gear off on one of those first few flights. This plane, when set at recommended CG, might be looking for a lot of runway to get slowed down. DO NOT be tempted to set it down to try to scrub off some of that speed. You can play that game with smaller planes, but with planes this size that's not a good plan!
Suggest that maiden flight, once things settle down a bit, include an exercise regarding an exploration of how slow it will go in anticipation of that landing.....
Best of luck!

I got the maiden flight done today. Just needed one click of right aileron and one click of down. It was flying real nice and the engine was running great for about 4 minutes. Then it just about quit, it would not take any throttle so I brought it right in and it landed like a *****cat. I thought maybe it got hot or was a bit lean on top but it did not sound lean. The engine was not hot on landing. I ran it up on the ground and it would not take any throttle, I opened up the high and it had zero effect, same as the low. I pulled the cover off the carb and blew out the jets with my fuel pump and all seemed clear. So I tried again with the same result. I tried to see if it would take throttle with the choke but that would not work either. I pulled the plug and it was all wet. I suspect the ignition died and will not support any spark above idle which is how Rcexl ignitions commonly die. When I get time I will try another ignition to confirm or find the problem and fix it. Othewise it flew great. We put a radar gun to the little Sportster 60 I built from a kit this spring. It does 121 mph in a shallow dive and 100 mph in level flight. What a little rocket. Nothing like the docile flight of the Giant Sportster. Here are a couple pictures I took.
