to type pop in to my mind:

UHU-Por type (conctact glue type)...
Here in HK version, thinner but 98% as good as the Brand stuff, and cheap
or
HOT-melt Glue...

the UHU-por types remain, gooey/rubbery when all dried out.
the HOT glue stiffens to a not that flexible glue, and can lose grip it banged into the ground (the plane)

ps: i use uhu-POR LIKE, on my indoors -works superb.

The Sylvan Aircraft flying wings are glued together, at least mine are, with epoxy.  Wings are EPP.
 
It's the recommended glue, and it DOES NOT fail.  This includes one that I eventually did crash to death (that final 60+ mph hit on the chain link fence did it in).  I've had the foam bend, crush, and tear.  I've never had an epoxy joint fail.
 
No offense intended, but are you sure you correctly prep'ed the surface before gluing?  I find that incorrect surface prep is the cause of a lot of glue failures.

NEWER USE EPOXI, on EPO/EPP i does NOT BOND !!!, seems so but does not, you can tear it apart. it fill the pores, bur does not stick to the foam, making it look like it does work, but under load it can break up...

YES i have tried it, just did it today, with a crashed Super Sabre - the EPOXI snapped clean off one of the body-halves...

I got a few EPO kits, they all came with a small tube of what seems to be regular contact-glue/cement. It works very well.

MULTIPLEX's EPP, can FAIL with epoxi, even it you prep it right, degrease it with alcohol and so on.

there manual even state it, DOT use epoxi.
-but hey if it works for you, go right ahead

  In my experience i found the same outcome that blindvision has had. I only use 4 types of glue now UHU (great contact cement and bendy, good for people that touch the ground lots) CA (again great but brittle, likes to crack on little crashes) Gorilla glue (amazing product, i now use it over epoxie, and there are a lot of variations) and the good old hot glue.
It's A DUCK

Polyeurethane expanding variety.

Been using it for a long time now and it's brilliant

Multiplex airplanes, at least the three I have (ezGlider, Magister, Acromaster) are all elapor, not EPP.  I believe that elapor has some EPP in it, but it is definately not the same as EPP.  All you have to do is hold a piece of each and it's obvious they are different foams.
 
Yes, the manual states to use non-foam safe CA on elapor, which is what I've used.
 
I'm not saying that epoxy is good with elapor.  It may be, but I don't know because I've never tried it.  I am saying that as far as I can tell, epoxy is just fine with EPP.
 
Here's the thing.  With severe crashes, I've had the CA joints in elapor fail - and I'm not suggesting that's unreasonable, my poor ezGlider has had a hard life...  However, my first Frenzee also had a hard life, harder in fact than the ezGlider, and the original epoxy joint holding the wing halves is still intact.  My failure rate with CA'd elapor is much higher than my failure rate of EPP glued with epoxy - and I'm talking about the cheap 5 minute ($.89 on sale) from Harbour Freight, not something expensive from West or System Three.
 
Another note.  I've had my Frenzee (27" wing from Sylvan) tear next to a previous tear that had been repaired with epoxy.  The epoxy joint did not fail, the foam tore next previous repair.

Has any one used either Beli Zell polyurethane glue or the recently introduced Gorilla Super Glue on EPO?  Gorilla Super Glue is not the same the regular brown or white Gorilla PU glue, but a 'rubberized medium viscosity CA.  Gorilla SuperGlue looks as though it might be ideal for EPO because it claims to be less brittle than normal medium CA. However, I haven't tried it yet!

My Fun Cub (Elapor) directions state that Only Medium CA (not foam safe) should be used and that kicker can and should be used as well. I just built the kit with this method and it is strong as can be.

For EPP I use epoxy and have never had problems. It will melt beyond first layer and will NOT peel like it does on EPO and Elapor.

In my experience the Gorilla takes too long to dry and is a real mess, though it does work superb.
Thats the ugliest hat Ive ever seen...looks good on you though.
