Dan,
I definitely think you have an AFT CG problem, although that number
indicates you are right in the center. First, I would carefully check those
numbers. I flew a KR with an aft condition and it acted just like you
describe.
At one time I considered the 2200, but it would have been too light, so if I
were to use a Jabiru, it would have had to be the 3300 and then I would have
to move the engine forward slightly.
Here is some data from my W&B
Datum is Firewall = 0 inches
Leading Edge of wing = 12.3125 inches
Forward C.G. = 20.125 inches
Note: Specifications state 8-16" aft of the inboard wing leading
edge
Rear C.G. 26.125 inches
For N64KR, the CG range is 8" to 14" aft of the inboard wing leading
edge.

See you at the 2012 - KR Gathering in Mt. Vernon, Il - MVN - 40th
Anniversary
There is a time for building and it is over.
