Most of my recent ARFs: GP, H9, etc. have had wrinkles to deal with before they were flown for the first time. You can't expect a kit that has been shipped to the U.S. all the way from Asia and then stored for who knows how long in a warehouse, to be "ready to fly" right out of the box, especially the covering. Most manuals ask you to use a sealing iron and/or heat gun to tighten any loose or wrinkled covering, and that's exactly what I always do. By the way, I had a Laser 200 and other than the initial re-tightening of the film, never had any issues with the covering.
