I must say I am a little nervous about it, But it would be sweet. Please give me you're input, it would
really mean alot to me. If I did do this, I could post the photos and info. to the group. What do ya think? Mike Johnson Well in a word quoted here many times, it is experimental so.... My advise would be to talk to Steve Rahm over here in Daytona, with Vision Aircraft. He basically has an improved (KR2S on vitamins) version of the KR2 which is all fiberglass like the Glasair (also an improved KR2) with different airfoils, but with all the same design ideas and goals. He can tell you about how the balsa wood density difference(?) would/might effect the fuselage strength, and ideas about what you might have to do to adjust for the changes. Also Dan Diehl could possibly enlighten you on what effects changing the core material might/would have on the structural strength. Take a look at Edward Barrios' site. He completed an entire fuselage with glass and foam, using only the wood framing without covering, and glassed over similar to making wings. I would make some large pieces by the plans, then make some large pieces how you want them, and test each set to failure and compare. Just my humble opinion.... Colin Rainey brokerpi...@bellsouth.net
