After years of powered models, I am finally getting my first glider. I am hoping this will be my gateway drug into soaring. The QF2 looks like a well designed and fun discus launch. I read the manual online and construction looks simple enough, but I do have a few technical questions. First the manual recommends solar film lite for the covering. I don't have any experience with the lighter iron on films and am wondering if there are any other reasonable alternatives? Also for the fuselage box, it says that glassing it is optional. Since the box is made from 1/16th balsa, it looks like the 2 oz cloth will bee needed to give you any kind of well, relative durability. Also any good advice on finishing resins? I have good experiences with Z poxy products.
