I am finally getting around to covering my son’s Midwest Super Stearman. I have covered a Sig Hog Bipe and a mini Ultimate Bipe before with absolutely no issues. I used the really good RC universe tutorials as a guide.

I am setting the iron at 220-230 degrees. I started with the control surfaces (aileron). I provided a pic so you can see how it is built up.





I am using the exact techniques that are in the videos tutorials. I am tacking first around all the edges and then sealing the edges. I am trying to remove as many wrinkles as possible by pulling around the edges before tacking with iron. Once that is done, I start to hit it with the heat gun. This is where the problem happens. I get around 4 to 5 inches away from the aileron and start to move in a side to side movement, making sure to stay away from the edges. The wrinkles start to magically go away and I am thinking this is a beautiful thing. As soon as I stop blasting with the heat gun and let it rest for a few seconds the wrinkles start to come back. They don’t all come back, but it definitely is not drum tight. So I hit it with some more heat, only focusing on the areas that are loose and wrinkled. It will go away again. I will let it rest and guess what, the wrinkles come back.

What the heck is going on? Please help!!!
