    Posted: 21/Nov/2010 at 10:15am
I have just received the Durafly Cessna 182.In the instuctions it states not to use epoxy (arildite)to repair the model and only use CA glue.I have used epoxy to repair foam models before and wondering why I can't use it to repair this model constructed of EPO foam.
 Has anybody repaired EPO foam using epoxy or is it best to stick to what Durafly recommend .Any advice would be greatly appreciated.

You can repair it with epoxy but it will just fall apart as soon as there is any stress on the aircraft, ask my stepson he'll tell you. CA and kicker onlySmile

Checkout this tread on it, from the Workshop part of the forum.

Quite interesting, on that very topic, Glue with what on what material.

Epoxy on foam? No thanks.
It turns a foul yellow, smells, and snaps off again pretty quick.
CA is better but I still think thats too brittle for foam.

Personally I prefer shoe goop, UHU por to glue the main fuselage bits.
Rubber cement keeps the natural flex of the foam so it will go with the flow rather then snap.
Only things I glue with CA are control horns, because you dont want any flex in those.

huhuhu found this thread. Learned my lesson.


5 minute epoxy trying to glue diy landing wheels on an EPO foamy.

Fell apart so easily.. just.. peeled off and never ripped a single piece of the epo foam.. *LMAO*.


No more epoxy on EPO for me.

I have used 5 min epoxy for all my Depron planes, to excellent effect. I've never had a joint let go on me - usually the foam gives way long before the glue lets go.

+1
I sometimes mix baby powder to epoxy to make it white to blend into white foam.

You're talking about depron aka EPS.. Those you can use epoxy.



EPO.. NO WAY.. it doesn't work.


I read all the comments on HK scale epo models and users complaining about the stock glue.

I take the stock glue ANY DAY over the 5 minute epoxy.


Even hot glue is more viable but heavier.

EPO + Epoxy = Bad news.
