Just FYI, Kitfox factory has an alignment check method they sent me which is the same idea as Phil's but somewhat different. It uses snapped chalk lines on the floor and more importantly a 4' straight edge aligned fore and aft with the wheel hub rim. The measurements are taken from the ends of the straight-edge in to the fuse center chalk line. This magnifies the alignment and makes it much easier to adjust compared to measuring across a 6" wheel hub. Many ways to skin a cat. My Grove landing gear needed no adjustment.
