Here is a silly little Idea that has a decent cchance of working. ( My brain works really good in the morning. However at night I can hardly tie my shoes.)
Take a spray bottle and mist the inside of the airplane. then secure it to your workbench. Water won't hurt the covering, and if you just mist it, you shouldn't harm the glue. Using your wingtube and stab tube put an opposite twist in the fus. with a makeshift jig. ie wook clamps ect. Over twist it slightly.(just a hair) Then reshrink your covering and either use a hairdryer on low heat, or let the thing dry on it's own. make sure it remains jiged and slightly over twisted the entire time. I'd let it sit for atleast a day either way.
just thought of the jig. Get two pipes, dowels or simular. extend your wingtube and stab tube with such. then add weight to opposite sides out at the end of the dowl. an old sock with sand will hang on it just fine. adjust your weight to get the right twist.
