I had to reinforce my Tribute 3 weeks ago. I used epoxy but I guess I didn’t make the correct mix. After 24 hours it was still like rubber. I placed the plane on top of our oilheater (+ approx. 45 degrees Celsius) for 4 days, and it finally became hard.

I was recently told, that it is no longer allowed to use epoxy glue on 1:1 scale planes made of wood. They must use white carpenter glue (I don’t know if that’s the right name), because the epoxy glue doesn’t penetrate into the wood – even under pressure - like white carpenter glue does.

Of course you will have to use epoxy glue where you have fuel or have to glue wood and another material together. (Araldit 24 hour should be even better than epoxy and never use Araldit 30 minutes). In that case, it’s advisable to make a lot of small cuts with a sharp knife in the wood, to get the biggest surface as possible. Sand paper will not make the surface rough enough.

Its advice able to have glue that’s flexible when it’s dries up (elastic glue sealants?). The longer it takes to dry up, the more flexible it is – so I was told.

When it comes to white carpenter glue, I was only able to find one type of glue here in Denmark that dries up flexible. The name is Casco Trælim Vinter 3303. Here is the data sheet translated to English with Goggle Translate:

(The Danish word “limfuge” is “glue sealants” in English – correct me if I’m wrong).

I don’t know anything about glue from RC manufactures.
