I've moved on from the flaperon Angle of Incidence - I'll come back to it.

Next question: flap push-pull tube adjustment. No matter how hard I try, I can not get the angle between the flap tube control horn and the bottom of the plane to 11.5 degrees - there just aren't enough threads on the push-pull tube screws. Best I can do is 13.5 degrees (see picture 1 and 2, below). But, even if I could, I'd never be able to get the flap handle into the #3, full flap detent. The mixer tube hits the bottom of the cargo area (see picture 3 and 4).

What am I doing wrong?
