Question
Best glue to use with HK MX2 EPP (has epo foam in middle)

My MX2 arrived and it looks very good it has epo underneath the epp (which seems like a good feature), but what glue should I use for glueing the wings, stabiliser etc? I don't want superglue to leak through and melt the internal epo!

I have one glue that is epo foam safe but it foams up alot and maybe is not ideal for flat surfaces for this reason.

I'd use 3DHS Foam Cure. It is clear, doesn't expand and it is flexable like the foam it is on.

Thanks, I'll look at getting something like that.

One I do have here already is a 2 part "epoxy adhesive" is this any good for foam?

If you wanna keep it simple just get medium ca for LHS and get some kicker... Easy peasy. Never seen anyone use epoxy on foam only balsa... Might start getting heavy if used a lot and don't know if it eats through

But the ca would melt the internal epo foam if it leaked through, I assume the kicker makes it set faster but it could still melt some foam, right?

I'm pretty sure foam safe Ca won't melt epo... I think it might melt eps, but epo I don't think it will do harm to.

I was always testing on polystyrene and I assumed if it melted that it would also melt epo.

I used epoxy on my Skywing/Wattaplane MXS for the whole build with great results. I used a tooth pick to get it into the hinge slots and then wiped any excess. Still holding strong without any show of loosening as this was all I had in the shop when I was putting it together. John
