It's the latter, Although it would be nice not to need any trim, what i do not
want is to need massive amounts of trim to hold the nose up (or down). My
current aircraft had a nose-down tendency and no amount of trim would alleviate
the pitch down when pulling off the power. I eventually found
I hope more folks chime in on this. I wills ave this topic aside for when I
make my build. So far, it looks like horizaontal stabilizer incidence angle,
and size of tail are to be considered. I want neutral trim at all speeds from
60mph to 200 (if my build is non-LSA spec)

If you are saying you want to build a KR that requires no movable
pitch trim tab, you've got a tough hill to climb. Every airplane is

No intent to stifle
If wing spars or whatever are being load tested, rather than make sandbags
one could go to the garden centre or agriculture supply and borrow bags of
chemical fertilizer. They will already have their weight printed on them
and so on.

the conclusion of the German Test of the Kr Spar and WAF's calculated by
Otto Bartsch is: Any reliable built Kr with a MTOW of 1050 pounds is a 4,2 G's
plane with a 1,45 safety factor,or a 3,8 G 's x 1,6 plane!
Otto Bartsch assured me,that the calculation was carried out somewhat
cons
That's nice to know...
Thanks!
