Maybe I should rephrase that statement. I considered it to be unsafe for me

I think Mark stated it very clearly. When the CG goes aft, the KR becomes
less stable. Jim Faughn started really pressing this issue many years ago,
and I believe that now all KR builders have adopted the standard envelop for
the KR of 4" forward and 2" aft of CG.

The issue of stability has been a major topic of discussion since the KR

You forgot CG location. When comparing notes on stability, it is

Jeff,
I would be interested to know what, if any, modifications your KR has that
might be responsible for its better than average stability? Is it a KR2 or
2S? Where was your CG vs the aft face of the forward spar (or some other
reference) during the recent "hands off" stability check?
Thanks,
Ken,
There's nothing special about my KR. See the 2002 gathering photos for
pictures of it.
It's a -2S that was started before there were -2S plans. Consequently,
it is really a stock -2 with a 14" stretch in the fuselage and a
streamlined canopy.. The only thing significantly different is tha
Excellent results. Gives me hope for mine. Not that
I really need hands off capability, but it's nice to
have.
