Amen Tom,
You put enough weight on the nose of any plane, and it will snap. I have been temped to put a Giles together just to "rebel" against the concept that the "Giles" snaps. CG, airfoil, wingloading is everything. I've seen the WH Giles video. It's an awesome plane!
BTW, how is the MX2 coming along?
I have a ZDZ-80 hot-rod, and wanting to put a few more square inches of wing area around it. The 91" Cap is looking tasty
