RE: P40-E 60 size ARF problems.
My problem is mixing the epoxy correctly. It says 30 minutes, but I have found that especially if i mix more than a few ounces, it starts getting hot (curing) inside 15 minutes. It seems to hold well though because I pull on the pieces after a day or so of leaving it alone and it does not give at all with all the force I can muscle. I am just worried about mixing epoxy and joining the main wings together as well as the tail surfaces.
