Given an angle, the wing dihedral is the amount the wingtip rises above the wing at the center of the plane.
Sine Ø = Dihedral ÷ Half Wing Span
So, a 4 degree dihedreal for a Blu Baby 33 would be sin(4 degrees) * 33/2 = 1.168.
Prop each wingtip up with a 1.2 inch block and attach along the centerline.
