I am never using monokote again, ever
OK, I'm going to cave in and use Ultracote on my next plane, an Uproar 40. I personally have been amazed at the amount you can get Monocote to shrink using the heat gun after the edges have been tacked down. My last plane was a TF Corsair that turned out rather nicely using Monocote. I've never covered a Cub wing, but I can't imagine it being as complex as an F4U wing.
I'll admit that I've never done a complete plane in Ultracote, only the bottom of the wings on my Super Skybolt. After a recent conversation I had with a fellow flier at the local field about his beautiful Ultracote covering job, I'm going to try it again. This time on a complete plane. Bend it around some real corners. We'll see MinnFlyer, we'll see...
For the record though, Monocote is a usable product and should be tried and not dismissed because somebody got a wrinkle.
