Corrugated plastic is heavier than most grades of eps foam, but it has been used to build RC model airplanes.

Anybody who would like to find out if this stuff can be run through a Phlat Printer could probably wangle some from the nearest supermarket or Wally-Mart store where it is used for temporary advertising signs. If that doesn't work, check out sign printing and silk screening shops in your area.

 

I'm a big fan of coroplast. I like them better than the foam ones since they fly better in the windy condition I have here. Once my driver boards are ready, I was going to try to cut some out.

 

i have been wondering if it would work in the Phlatprinters too. i have a whole brain full of ideas but using a razor is a little hit and miss when you are cutting across the flutes. i think coro is the logical next step past foam when moving up in size. balsa has to built up into shape but coro can be bent and molded like foams can be. weight can be a factor, but building and planning of your design will cut some of that and they bounce!!! that is an upgrade. just fly faster and you will never know the difference!!!
