I am going to step in here at this point and say "Whoa pardner!" Yes, you can be a millimeter off in some areas with very little penalty, but in other respects a millimeter difference can defeat your ability to get off the ground ... or another millimeter placement of the balance point aft of the c.g. (center of gravity) will improve control response - but can produce a sharp stall with a tendency to roll inverted... Although I am an EMC cnc machine builder/enthusiast, I am also a licensed glider pilot (N71J) and I have some experience with model scale aircraft design and composite structure fabrication. I have friends in the business of full-scale composite repair/modification - and most importantly I have known and discussed airframe design & modification with respected designer-test pilots who are now dead. Right here & now, I am seeing a lot of uninformed speculation about airframe design flying back and forth, and this is not the proper forum for speculating about such variables as wing thickness, spar design, dihedral, etc. At the very least, I suggest that you think in terms of breaking your endeavor into 2 components: ie: 1.) cnc machine design 2.) airframe design and fabrication Tom ------------------------------------------------------------------------------ Apps built with the Adobe(R) Flex(R) framework and Flex Builder(TM) are powering Web 2.0 with engaging, cross-platform capabilities.
