Full disclosure...when I first rigged the basic wing panels to the fuselage, there was insufficient dihedral. As I had already epoxied the joiner boxes in place, I had to resort to bending the wing joiner blades. Although I'm pretty sure I modified the drawing, a dihedral check at this stage with the joiner boxes clamped in place is probably a good idea...
Note: With the correct dihedral, the lower surfaces of the outer wing panels should be in line with each other, thus giving the upper surfaces a slight anhedral...

Adam, these days I prefer to use 0.6mm ply: lighter, easier to bend and still suitably strong...
