Kim,I made my centersection 3' wide, which required modifying the cabane strutattach fittings (not a big deal - just something to think about, and itallows for a larger fuel tank in the centersection). I would agree thatadding a foot to each wing is probably a good thing, but there are somethings that should be considered.1. I would move the lift strut attach points outboard so the strutscontinue to hit the middle of the spars. This keeps the lift pretty muchcentered on the struts and reduces bending stress in the spars. 2. If you make the wings longer, you might seriously consider adding athird or even a fourth bay of drag wires and compression struts. The dragwire angles involved with the standard Pietenpol wing are more acute thanany other airplane I know, and this tends to really increase the loads inthe cables. Most airplanes have the drag wires cross the anti-drag wires atpretty close to a 90=B0 angle, but the Pietenpol tends to cross at more like a45=B0 angle. Making the bays longer just exarcerbates this.Other than that, I can=92t think of any problems that making the wings a footlonger would cause.Good luck!Jack PhillipsNX899JP =93Icarus Plummet=94Raleigh, NC-----Original Message-----
