'Hi all,
Today I pulled the envelope up onto the fuselage and it doesn't fit. Right behind the passenger window the fabric is as taut as possible, The seams are strained to the point of looking like they might tear. I've heard it said that if the envelope doesn't fit you have a fuselage problem not an envelope problem.
The only place where I can adjust the fuselage is at the bottom. The bottom outside longerons are both covered with a balsa wood bumper. If I shave it down I think I might be able to get the fabric to move freely over the rest of the fuselage.
I called Poly-Fiber but they are closed for the weekend. Any suggestions?
ThanksGeorge

'George,

Remove envelope, stick in box and send back to Poly-Fiber:) Purchase blanket and install fabric.

Envelopes are terrible. Start with the bottom first. I stopped using 20 years ago.

'George,

There are TWO sizes of Fairchild 24 envelopes. One is the pre 1938 (three place?) version, and the other is the 1938 and later (4 place?) version. The latter is about six inches wider. I had that wider pattern created for me (by the Aircraft Supply Company in Georgia that was later purchased by Aircraft Spruce) when I ran into the same problem that you did. The wider envelope fits perfect.

That said, I don't think that you save much by using an envelope. It is easier to understand how to install an envelope, and seems less daunting, but I think overall you would get a nicer end result without an envelope. I am very happy with mine. It is a lot harder to do than it looks, but I would not use one again.

'Bob,
Thanks for the heads up on different sizes. I'll ask the owner what he wants to do. I prefer using blankets but the owner purchased the envelope before hand. I'm not sure that he knows much about the history of the aircraft, I know that the wings and the fuselage are from different vintages. The size issue was huge. Thanks again.

'Thanks. I appreciate the sentiment, but I was given the envelope by the owner. Now I can go back to him and suggest we do it my (and your) way. Blankets.

'Glad to hear that....I've been looking at the Stewart system for several years for my Citabria. What attracted me was one paint for both metal and fabric so there is no color shift between the two like on Dope and other paints.... They may have the same number and title but the shades are off between metal paints and Dope.
