I finally managed to find a finnish depron supplier.

I wanted to try something different: http://www.careliawin.com/tyson/RCMig7.htm

Wing Area: 10 dm2 (153 sq.ft)
Weight: 200 grams (7.1 oz) with 6-cell 250 mAh pack
Wing Loading: 20 g/dm2 (6.7 oz/sq.ft)

I used plans (Dave West) designed for coroplast. But as you see, just with a few modifications, these plans are very suitable for depron too. Does anybody know if there are more coroplast plans available?

Dickk, (Ha! No asterisks!)
Depron, like Styrofoam (capitalized because it's a DuPont trademark) is the european brand name for a thin styrene foam material, identical to Hefty brand foam dinner plates and meat trays. Ask your butcher! It is availabe in different thicknesses and densities, though the only source in the U.S., Peck Polymers (http://www.peck-polymers.com/) has just 1/16" and 3/32" thick sheets of 11" x 17".
Coroplast is another brand name for extruded corrugated plastic. It is the durable replacement for corrugated cardboard and it is commonly used as the backing for temporary signs, USPS mail tubs, etc. I got a 3' x 10' feet sheet of it for free from the San Francisco Muni bus yard. It happened to be an ad for Ringling Bros. Circus that rode on the side of a bus the three previous weeks. Sometimes it is available at craft stores for signboard material. It comes in different thicknesses as well. Now that you know what it is, you will probably see it everywhere!

Wow, I'm right on top of thing! I just saw Gordon's reply to your question. Much more thorough than mine. I should say that Hefty Colors may be the cheapest source, and they are available in red, white, blue and yellow. The inner flat part is about 5" in diameter, 1.5mm (1/16") thick, and weighs in at 10.8g/sq. ft. or 100g/sq. yard or 120g/sq. metre.
There are some very good European web sites that explain how to work with Depron, I just don't have them bookmarked. Maybe Achim or Jochen have them.

Thanks John . So I've been using depron with out knowing the name. Made rubber models with meat trays. Am goin to try and find the underlayment that Award floors use for their underlaymentr. I understand its a blue foam, rigid and only 1/8 thick.
You can find out a local sales rep for your area, large area tho, like the North East etc. at www.awardfloors.com. (http://www.awardfloors.com.)
Its called QS3.O Underlayment. for wood floors.
