The plane has a huge crank is 3.125 long, not sure if that changes anything? How does the spacing of leadout induce yaw? I would think that going from 3.125 from the bellcrank down to .5 leadout would cause alot of resistance
Where the bellcrank is located is of little importance to yaw.
A 3.125 bellcrank is not huge...it gives better control than a 2" crank.
WHERE the leadouts exit the wing is the important part. Having them adjustable allows you to trim for best flight. Part of the "trimming " process is to move the leadout position for best performance. This position will change with different length, diameter, and type of lines you are using. I would suggest you do a search on trimming to better understand what you are trying to achieve with the trimming process.
BTW, welcome to CL flying!
