These days I build the dihedral breaks and panels all in one go by using a pair of building boards angled upwards to match the dihedral angle. For polyhedral I start on one side and work across to the center and then over to the other tip by only cutting the spars and leading and trailing edges to length. THis way I build around the dihedral joints and can fit everything quite finely.
Very cool - how do you setup the building boards? Do you have a picture? I am very interested in that technique. Thanks!
