Not to upset anyone, just me putting my two cents in as a newbie..

Isn't the definition of an unstable aircraft basically that if momentarily
disrupted from it's flight path it will not attempt to return to it's
original state, but instead continue to diverge from that state.

I'll say it's pitch sensitive. It is also dynamically unstable in pitch.
Whether builders want to accept it or not, the original KR-2 tail in the plans
lacks sufficient horizontal stabilizer to stabilize it in flight. The lack of
stabilizer makes it very sensitive to upset by control inputs and

Doing a google search for " t
I would think the VG's would make the elevator have more authority and thus
more sensitive than without though the only way to tell is to put them on and
try it.
As far as pitch sensitivity is concerned I don't think the KRs are sensitive at
all. I flew both Martin Roberts KR and Steve Alderman

Ok changing the subject line here - I've been experimenting with the
"Landshorter" VG's (Landshorter.com) I placed 48 VG's on each wing
(including
the stubs) there are 100 total supplied. The instruction provided state the
position range is 8 to 12% of the chord with the most common being 10%.

Sounds like a lot of work for little benefit. I had heard of much more
dramatic results when using these on another type, but can't remember what
it was now.

One of the older BD-4 newsletters had a writeup about one of the builders
testing
them some time ago. I'll try and find the article.
I may have been confused, the article wasn't in any of the
newsletters that I can find, but these 2 links do discuss
them on a 4.

Bob,
go to _http://www.landshorter.com/_ (http://www.landshorter.com/) he
explains what and how they do it and there are a lot of testimonials as well.
