If I hadn't used fabric and paint on a number of models I'd think it was difficult after reading the responses so far. I've built three planes using plastic film, the rest are fabric and paint and although fabric and paint takes longer it's a lot easier and nothing compares as far as looks.

Glassing would not be the best way to cover a hog bipe, fabric would. Do a search on using Koverall and dope, I remember several threads recently and they have all the info you need. There's absolutely no reason to sheet the wing or the fuselage, real biplanes have open bay wings and stringers on the fuselage. There's also no reason to fill the fabric with so much paint that you can't see the weave, on real fabric covered planes the weave is clearly visible. You only need enough dope so there are no pinholes between the threads and enough colored dope to make a nice even color.

The Super Stinker pictured came in at 13-1/2 lbs with fabric and paint. All the old reviews I read came between 14 and 15-1/2 lbs. with monokote, so fabric and paint does not have to be heavy.
