I found Blue foam board at a local DIY market (GAMMA). This foam is used for sound reduction for a laminated floor. Very cheap foam, its for the budget builders.
Using only Google SketchUp I designed a whole RC 3D air-plane and it cost me very little!

You can see here it's maiden (first ever) flight. For a design I created in Google Sketchup the model flies VERY well, I did notice the wings flex too much so I added 3M Scotch filament tape which fixed the problem.
