Help... corrugated metal!
Any Top Gun competitors out there that have a supplier/building techique/material/dead cert' method of faking corrugated metal for control surfaces on a 1/4 scale?
Please help... I beg you... trying to produce anything that looks real is driving me mad!
Cheers.

Corrugation...inward or outward?
Outward ridges are easily accomplished with appropriately sized square or triangle stock depending on what the full size used. It begins with photo docs and the degree of compliance to satisfy the photo doc... 
Inward recesses are extremely difficult to create without use of a step and repeat jig and either a Dremel trough similar to a dove tail jib except you do a drop down and move forward and back with a ball headed cutting tool. Get the picture?

Plastruct does have corrugated sheets. They are about 8"x11". I used it to form the gas tank/center section on my 1/4 scale Tiger Moth. It looks great and is easy to form. Would post a picture, but I left my camera at a friends place in Seattle.

Plastruct has 3 corrugated sheets #'s P-25, 26 & 27, but I don't know which is what. When I bought the stuff, it was just sitting in the diplay at the LHS and I didn't pay any attention to the number on it.

One of my LHS's has thin spruce (hardwood) strips, some as small as 1/16"x1/32", that I've used for "built-up" metal corrugations on balsa. Properly sealed, sanded and painted it ought to outlast the styrene pre-fab'd sheets.

If you go to the Plastruct site, the part numbers are PS-24 through PS-27 for different scale corrugations, at approx. $5 for a 7x11" vac-form sheet.
I recall seeing a scale Fokker several years back where the builder had routed a forming block, and embossed litho-plate to create his own corrugated sheets. Lots o' work!
