Per Ivan Shaw in one of the newsletters, in disscussing his flight
experience in a Subaru-powered Europa (70 lb. heavier), the increased
moment of inertia has some effect on flight characteristics, but
remains stable. He feels it's most critical on the monowheel in the
takeoff/landing phases, requiring more skill on the part of the
pilot. Just another consideration in weighing pros/cons of a heavier
engine, and perhaps more significant to some than just the payload
penalty.
