Talking about bellyboard ground clearance !! The Longezes had a spring loaded bellyboard. The idea was to prevent deployment or to cause retraction if too much airspeed/air pressure was applied to them. The same principal could be applied to the KR2. One of the ideas that flashed across my brain is if the belly board was close to the ground when deployed with a spring loaded extension system, then hit something as in a rough field landing because lack of ground clearance, the springs would absorb the shock, let the belly board flex up instead of tearing up a direct linkage system or your electric motor drive, then re-extend itself once past the obstruction. Another thing to be wary of is placing the extension rods or motordrive where it could jam into your spine if you landed hard enough to damage the bottom of the aircraft. Larry H.

Are you sure you will have enough ground clearance? I'd want nothing less than 6 inches clearance and that's plenty close. Larry Flesner
