Good question, I have giving it some thought but not finalized how Im going to do that, what I came out was that I will cover the wing and flaps, then glue the hinges to the flap and wing at the same time to make sure the gap is the same, once that is dried I was thinking of painting the hinge covers the same color as the monokote then glue them over the hinges per the instructions, the other way to do it is to glue the hinges, once the glue dried then cover them with monokote, I will be using six10 thickened epoxy.
