Victor,
Maybe I wasn’t clear enough.
My point was not to add weight because I did a bad job establishing a proper cg
during construction.
There are instances when pilot/passenger weight fall outside the established cg
envelope (I.e. a lightweight glider pilot in my case) or a heavy passenger in a
KR.
Moving batteries or engines?! Around in these cases is …..

Rather than adding weight to bring your CG in it makes more sense to move your
battery or even the engine if you can.

When I was started to take my first glider lesson…. I weighted about 130 lbs
and before each flight I had to install a 25 lbs “lead cushion” under the seat
of our trusting ASK13 to bring the cg into an acceptable range.
Years later I didn’t head my own advise and flew another glider with an aft
cg…. It abruptly entered a spin and only sufficient altitude saved my a…
While my KR2 is still in my workshop, I will definitely plan to “adjust” my cg
with weights if needed.
A proper cg is serious business.

Very good post. I've deliberately not trimmed this response since Gary's post
below sums things up so nicely.

Colin Hale sounds like the real deal. If he's written a book, it's next on
my read list.
When I read "When I left Alaska for Russia, laden with 220 litres of fuel on
board, or 55 US gallons. I could hardly lift the tail wheel off the floor and
knew already, without scales or maths or charts, that the C of G was beyond the
aft limit, in the divergent range."
I knew he was competent, but today he wrote
" but why are so many plots wanting to say, "I flew mine way beyond the aft C
of G limits and it almost killed me! "
What the hell do you expect?"
What I expect is that if Colin flys a KR at aft CG he will arrive at his
destination. If I do, I might. If a green pilot tries he won't.
The KR is a delightful airplane. Fast, fun, & cheap. A novice will have his
hands full at forward CG and MUST NOT carry his friends till he has it
mastered. When he has it mastered, he will know what not to do.
