Bellcrank deflection versus leadout length change.
Inboard wing: 28"
Bellcrank: 4"
Leadout separation: .5"

Four degree max difference for this arrangement.

So if you trim neutral at the handle after finding optimum L/O offset, and assuming you keep your B/C at neutral, will this L/O angularity effect the elev. throw (up vs. dwn deg.) enough to matter?

Who knows what his definition of offset is?  Who cares what the bellcrank does?

This has been completely determined, with diagrams showing the parameters and their definitions.  What's the point in repeating it halfway?

Tom,

I don't know who you are, but I like your reply.

You're thinking, "out of the circle!"

That phrase, coined by Avaiojet.  ;D

I have plenty of interest in Bellcrank placement and I know a bit about it.  n~

Always room for conversation.

This could turn into a real 'circular argument'.

Tell us more, please! Particularly your knowledge about bellcrank position relative to the CG.

The bellcrank position relative to the cg is not in this model. I have only worked out the relative mechanical connections  and response of the entire control system. Not knowing the lift and drag coefficients of the various surfaces, and fuselage, as well as the  thrust of the propeller when flying 'yawed out' would be a real handicap to quantifying this behavior.

I could tell you in a qualitative way, if it would make you feel better.
