I am an beginner to RC and am trying my hand at building and flying from the ground up. I am starting with the Condor40H. In the build instructions it says to cover the plywood fuselage panels with epoxy before covering them with the balsa overlay. It seems to me that a good wood glue like Selleys Aquadhere (Austalian product) would be more suitable and easier to use. I will use the epoxy for the strong joints as stated. Is the epoxy crucial?
