My KR addressed that issue with a 24" fuselage stretch. Larger tail
surfaces would be additional improvement. An enlarged tail, extra
width in the fuselage, and better aerodynamics at the wing / fuselage
junction are about the only things I would change in hindsight. Even
with those issues I love my KR. The other major problem I see that
makes KR's hangar queens is not having any "drag devices" to assist in
the landing mode. I would not be comfortable landing my KR every time
without a belly board. It totally transforms the landing
characteristics of my KR and makes landing on 2800 foot grass with
obstacles a non issue. With engine at idle and speed brake out I get
1500 fpm decent rate with stable airspeed control. A touch of power
brings that back to 500 fpm on a very stable approach.
