The paint shop sent me an email asking for balancing spec for the 170 flight controls. Where can I find this info.

So George, those number are for B models. I have an A model SN19810. A and B specs are different? Paint shop just called me on phone looking for specs. Shouldn't they have that info handy....

Why are the elevator specs so different from A to B

They changed to a counterweighted elevator on the later models for that fluffy light feel.
