I have looked at this also, and on the list of performance of the flying
KR-2's started by Orma about half of them have performance in the sport
aircraft rules,however it would be better if we redesigned the aircraft
to fit the rules and called it something else only useding the Ken Rand
construction techniques. I am building a KR-2S but may lose my medical in
the near future, that's why I was looking to increase the wing area and
span to improve the stall and climb speeds. I believe it could make a
great sport aircraft with less power.
