Some great info guys!
I really like the fact that I can post on here and get such a wealth of info/experience quickly.....
I haven't started surgery on the Citabria yet.
There is a bit of slop in the bellcrank linkage setup, though I'm sure it's no more than the original.
Right now I'm back to thinking how to cut the one piece servo to bellcrank linkage into two, then mount a round servo arm....
And that's a good idea.
You can get whatever differential you need right at the servo. No need to futz with the bellcranks at all.
You can also get differential by leaning the aileron horns, btw.
I'd describe how to do this, but I don't think the audience is interested.
