Like Gene said, it'll be much lighter if you remove the film and temper it.

I saved about 3/8 ounce by removing all the film.

Gene, thanks for the recommendation. I tried it tonight and it is indeed good stuff.

I have had mostly good results with Liquid Nails "Clear small projects and repairs" glue, LN-275. The tube is golden brown one one side, with a blue central area, and the words "exterior/interior" are written in the blue area, along with the product name.

It seems to work very much like the Uhu Creative, but is cheaper, and can be bought at Home Depot. It sets very quickly, perhaps 15 to 30 seconds. You have enough time to place the parts and maybe make one tiny adjustment, then they're bonded for good. (I think the Uhu Creative gives you no time for adjustments at all - once the surfaces touch, they're glued!)

The only downside of this is that it comes in a fairly big tube, and as I slowly go through the tube over several weeks, the glue comes out thicker and thicker, eventually getting thick enough so that it has to be spread with a popsicle stick or something similar. I have had some success thinning it with mineral spirits, but that makes it a bit of a pain to use. Still, its cheap, foam safe, bonds quickly, and leaves no foamy mess like the polyurethane glues.

Oh, one last thing: don't let this stuff dry on your fingers, it is surprisingly hard to remove from clean skin!

I haven't found the Liquid Nails "Clear small projects and repairs" glue... I did find the Liquid Nails perfect glue #1, though. Sounds real similar, but in a smaller tube. I found it at Menards. I felt like it was in the same class as the Uhu Creativ and GWS glue. I still like the ProBond where the strongest joint is required despite the slow setting time and mess.

I have found the best way to remove the skin to be with a broom handle. Simply start at a corner and roll the broom stick diagonally across the foam. It all comes off in one piece. If it tears at one of the holes, just use an exacto to lift up the part that tore and keep on rolling.

Probably... There's quite a bit of authority in big'ol tail If not enough, just make the control surfaces 50% bigger

I was asked to post some additional pictures, showing the control horns and equipment layout. Here they are

The Servos are hot glued to a couple of cross sticks (Starbucks coffee stir sticks) that are CA'd to the fuse stick.

The Control Horns are made from 3/4" long sections of Starbucks coffee stir sticks, and hot-glued into a slot cut in the control surface's foam.

I know the feeling. If it doesn't stop raining here I'll have to build an arc! At least it's just above freezing....

I'm really interested in building this plane, however the only motor/battery combo I have is an AXI 2208-34 and a TP 2s1320. I'm sure these electronics would push the 5 oz AUW kind of high. Without having to buy a CDrom motor and a tiny lipo pack, what could I do to the design of this airframe to accomodate the weight of my electrics? I still want the ultra-slow, maneuverable flight characteristics. I figured maybe making the wing a 36" span would help? (greater surface area/lower loading, higher drag= slower?)
Thanks for any advice,
Dan

Dan: I'd say yu are on the right track. I'd try sizing it up about 25%, which would be 35x10" wing, a bigger tail, and longer fuse stick. I'd probably go to a 1/4x3/8" stick for the fuse. I've thought about working on something for this power range, for a geared J-250. Should be able to be below 7 ounces.

Let me know if you need any help figuring it out...

I have a very similar plane, something close to your blustik but 40" span x 12" chord and it is powered with an axi 2208/34 just as Dan wants to do. It is nicely overpowered at about 12oz plus battery.
