(GG) in a pinch you can use Gorilla Glue, the white stuff. put a tad or little bit of water on the foam, use the GG and make sure the parts are in the right place. Wait 24 hours, you are good to go.
a lot of guys use GG if they don't have epoxy.

I use either foam-safe ("odorless") CA or Gorilla glue. Epoxy for motor mounts and such. For Elapor foam, you can use regular CA, and avoid using epoxy -- it doesn't adhere too well.

hot glue works well, especially with EPP...you have to use it sparingly with EPP though it acts more like a weld than glue on that stuff ..easy to "burn" thru the material and there can be a considerable weight penalty if you are not careful and use too much with it .

If you have a Home Depot close by(or Loews for that matter) ,you shouldn't have any trouble finding any kind of glue .Most all the glues we use in the hobby are available there,even though the packaging may not say so...just read the labels carefully for application of usuage.

Walmart sells a 5 and a 15 min epoxy that comes in a syringe...i've used this a time or two in a pinch and it works every bit as good as the "hobby grade" stuff ya get at the LHS.the only drawback with it is that the syringe is basically one time usuage, long term storage really isnt a good idea with it...find it in paint/hardware aisles...

CVS and Walgreens sells a CA that comes in a 1/2 oz bottle that claims "no clog tip"and it doesnt so long as you keep it upright ...it takes 3-5 seconds to set up so you have a little wiggle room with it ...find it in the office supply area.

The Suqhoi mini is made of EPS, so you really want to avoid heavier glues like epoxy, or hot glue (especially hot glue) or gorilla glue.

The stuff you should be using is foam safe CA. BSI's Foam Safe CA is the BEST stuff out there, and a giant 2oz bottle of it is like $15, and like $10 for a whopping 8oz of kicker (refill bottle- put a sprayer on it and it works). Prices do vary with who sells it, but it's awesome stuff, and usually shipping will only be a few bucks, say $5-$6

Chief Aircraft has the stuff in stock for that approximate price.

Uh oh I've had plenty of bad experiences with that stuff. Sometimes it isn't brewed right, and just won't dry without an accelerant. Other times it just melts the foam Also, IMO, it's fairly brittle compared to the BSI CA, of which is the only CA type I will be using from now on. It's brewed to the point where it will dry on its own in a few seconds. Also, that Zap stuff is only half an ounce. BSI's is 2 oz and the same price. That's like quadrouple!

IMO, use the zap stuff for balsa, and buy this stuff:

http://www.chiefaircraft.com/rcmsec/...sives/BSI.html

The product number "BSI128" which apparently went up in price to $18.95 (it was at $14.95 over the summer) and product number "BSI152" which is still the same price. That's also quadrouple the ammount for essentially the same price as Pacer Zap-kicker

UHU Por is better and cheaper because it maintains its flexibility and has great bonding strength.

I like the Yardbird ultimate foam glue. It doesn't take much so its light and it makes a very solid bond.

Glue

The glue I use sumo glue on epp and balsa combo. the fix in the field" hot glue."
sumo glue is the same as gorilla glue it just doesn't expand as much.
It bond the balsa to the epp in 15 min but takes 8 + hours to fully cure.
I bought it at home depot.
If i were bonding epp to epp I use hot glue.
I haven't tried to bond epp to epp with the sumo glue because it's an expanding glue.
