PJ,

Dihedral and pattern ships.

The Taurus is characteristic for any low winger and a source of information how they did fly their pattern planes in the past. Scratch build, no plans as useable and a lot of fine tuning while flying the plane. Months of work to count with all variables and interactions between them.

One of the variables is, wing position, wing setting in the fuselage and dihedral.
My example picture 1 I did change the horizontal position and the angle of the wing saddle as normally. I also did change the dihedral, see picture 2. You can see the coupled halves.

This was the only way to adjust a pattern plane because the Taurus is of the period of the Slow Roll. The Cream Puff of Vic Husak did have the adjustable wing center section for example so a development of 1964 / 1965 I think.
