RE: what angles are in polyhedral wing ?
Dennis, are you making a glider?
As you already have seen it's fairly open. More leads to better rudder response but it makes the wing less efficient. Less makes the wing more efficient but less responsive.
Generally the location for the outer panel breaks is chosen with an eye to making the front view of the wing sort of approximate 1/2 of an elliptical shape. This is also why a 5 panel poly setup has become more popular recently. A flat center, mildly angled mid-outer panels and then sharper upturned small tip panels. This keeps the major lift production in the center portion of the wing more efficient while moving the yaw to roll function of the dihedral out to the wingtips where it has more leverage.
