Don't use regular CA on that foam. It will disolve it. There is foam safe CA but it is a bit pricey.
Use the Super Goop but only a thin layer. Put clear packing tape on top and bottom to help reinforce it. (the dollar store stuff works well)
I used standard CA on my stryker fuselage without any issues but that's not to say his plane is made of the same stuff. Good point.
