Concerning the Stall speed reduction required for existing KRs to fit
MOSAIC,
I suggest a simple belly board that could be added to all non-flap
equipped KRs. I put one on my first KR and it helped a ton.

Configuring a KR to meet the Light Sport category has been a point of
discussion for many years on the list. Two problems. Clean stall speed
and top speed. I'm not aware of any flap design for the KR that would
lower the stall speed to meet the regulation and adding a speed brake
does nothing to lower the stall speed. The KR is such a slick design
that speed control on approach is difficult to stabilize without the
ability to add some drag. Stabilizing the approach goes a long way in
making the KR a more enjoyable airplane to fly. If and when the new
rules take effect any of the KR models build to plans will meet the
requirements.
On the subject of "full stall" and "three point landing", few if any
aircraft are capable of performing both on the same touchdown. Even
211LF, with it's 6" longer gear legs, will touch tail wheel before the
wing stalls and the mains still inches off the ground. When the tail
wheel touches it forces the mains to immediately contact the ground
making for a less than desirable touchdown. Most conventional wings
stall in the 14 degree range and few if any tail wheel aircraft have the
wing at that angle in the 3 point attitude. For those that insist that
wheel landings will result in more runway used on landings I'd remind
them that every tricycle gear aircraft, when landed properly, makes a
tail low wheel landing. That's my story and I'm sticking to it.
