I'm in the process of repairing a vintage Sig Liberty Sport biplane, which I know isn't a fine detailed scale model yet is the most scale one I own. It was originally built in the 1970's with some sort of really thick, heavy fabric covering. Well, that stuff was falling off the wings, so I covered them in that Coverite 21st Century fabric stuff. Halfway into the 5th flight, both wings folded to a 45 degree angle, but I was still able to land it without any further damage. I feel this covering didn't give much strength to the overall structure. I didn't use flying wires either, which certainly didn't help. Do you guys have any recommendations as to what type of covering would be best? I want to maintain a semi scale fabric look, so Monokote really isn't an option since the fuselage is still covered in the original fabric and looks good. I have only dealt with iron on coverings, so I'm not familier with any of the other types available. Any suggestions? Thanks.
