- Well, I'll add this: silk can be light, if you know what you're doing. The
- last airplane I completed, a Sig Skybolt, is silked. When I told fellow club
- members that I intended to silk the plane, all of them, to a man, told me
- that I was looking for trouble, that my plane would never fly `cause it
- would weight ten pounds. It weighs six pounds, full up. The covering,
- including color paint, is lighter than Monokote would have been. And it
- lends MUCH more structural integrity, and is completely fuel-proof. The
- technique for making silk light is rather involved, and takes a lot of
- work, but it is quite possible.
-
- Oh, if you cover using Nitrate dope, then fill with one coat of Nitrate then
- only white butyrate (the white fills better, and weighs no more than clear)
- for filler, tension is no problem. My open wing structures are drum tight
- (tighter than Monokote gets) and *will not* sag. The white areas have a
- total of four light coats of dope, the red and black areas have five.
-
- It also looks and feels *wonderful*.
