Thanks Jman: I am in the aviation field for over 30 years now, I work in engineering for a major 747 freight company, I wish to help out in any way ,I am NOT looking for money etc , i offer this up for free, My experience in composites and 3D drawings may help someone, I also like the home built types ,there is so much new technology and being homebuilt your not tied to the old school thinking, Thanks Respectfully 3DGuy
