I just finished my Lew's A-6 last night and flew it this morning in my 18 ft square space.
The wing mount baffled me for a while, but once I got it figured out it works fine and is easily adjustable for CG and incidence. It finished at 1.79 grams, which is my style (I'm old, my hands shake, and arthritis makes it painful to use my thumbs).

It flew right off the bench on 600 turns, gained a dab of altitude, circled left within the room, but has a pronounced Dutch Roll. It's built all to plan except that it has about 1/8" of washin on the left wing and 1/8" washout on the right (at the dihedral joint). The plan appears to spec a flat wing.

Why does it Dutch Roll and how can I fix it?
