My take on those two items is that they are more to eliminate complexity than eliminate speed. Certified aircraft with the above items help to put them in the "complex aircraft" catagory and require a check ride and endorsement. The Leolhe 51, or however it is spelled, has retractable gear and even with an inflight adjustable prop I doubt the Rotax would give it a speed to disqualify it from the sport pilot class. Just my humble opinion. Larry Flesner
