Don I can recall someone talking about flying in a Lake Amphibian and stating that you get alot of pitch change when changing throttle settings in this airplane. Since the engine is on a pedestal mount at least 18 to 24 inches above the fuselage, I thought this might be relevant to this discussion. Obviously several problems that had to be overcome with this design would not be a problem with just 5 inches, but it would seem to me that if 18 inches could be safe with 150 to 200 hp engines, then 70 to 100 hp should be able to be tested and small modifications made to keep a KR2 or S safe. Biggest safety issues seem to be power on stall behavior, and how large changes in power settings up and down would effect pitch. If it is in the same centerline position I find it hard to believe there would be any yaw change to contend with. Then again I am not an engineer...
