RE: how to cover a repaired wing
Go & buy a roll of monokote, when you open it it has an instruction sheet in the roll, The first plane I covered I used my mothers clothes iron, just have to play with the setting until you get it right. Believe it or not it was one of the better covering jobs I have done, so acctually you don't have to buy a covering iron if you have one of these handy, but the covering iron will be eaisier to handle.
