Hi all,
I built my Kr2 to plans. no stretches or mods. It has neutral trim with the C
of G at 4 inches aft of the forward limit. Either side of that due to fuel burn
or loading requires trim, but even on both limits I can trim my plane out with
a simple spring balance mechanism I have on the co
Most production aircraft are rigged to optimize cruise configuration. Trim
relieves control forces in non-optimized flight configurations. Peter
I do notwant to build in a pitch tendency and then have to fight it with trim,
or worse,have full trim and still have stick forces at various pow

That's not going to be a problem if the flying CG is he
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
full of c
