Don't ever modify anything from the plans if you build a kit or a

CAD-CAM designed by computers and you don't have the thousands of
dollars (or hours) available to you to check all the scenarios of your
modification.

Right . . . unless it wasn't. Never say never. Take the Christavia
for instance, wasn't CAD-CAM designed, tube frame is laid out on the
concret floor with tape measure and chalk lines and is modified as
necessary depending on what you use for an engine. Designer even told
me where to lengthen the fuselage and by how much, give or take. He
admitted he over designed it on purpose. It's hell for stout because
of it, but WAY overbuilt.
