Thanks. I never used or even touched Por-Formance foam but I was also amazed at your measuerd weight. I am sure it helps having that AR6400 brick, but still amazing. Thanks for the info on the foam and fans for sure. I bought some of those P-51 motors but have yet to marry them to an actual fan setup. I get off on tangents you see......
I too am amazed how light arcraft suffer little damage when they hit things. I think I am going to try Dave Reap's printing of sketchup to cutepdf file, then play with it using acrobat reader for actual paper printing. I have also been trying out Open Office lately because it can open pdf, and save to pdf, and may have some alternate potential.
Carry on and good to see some more of your designs and magic at work.
