A caution I've long heard applies to changing wings from fabric to metalized.
On the underside of the leading edge, the Ercoupe's airfoil has a small concavity. This concavity is important to the low speed / stall characteristics of the Ercoupe's wing. Some people converting the wing to metalized fail to make the new leading edge metal conform to the correct shape. If you are converting Coupe wings or have wings that have been metalized (as opposed to coming that way from the factory), you should check to see if the underside of your leading edge has this concavity.
