I am getting ready to join the lower wing halves together and I was wondering about the stock dihedral for this wing. It calls for a 2" block on one side, or 1" on both sides for the angle. Could this wing be built with 0 degrees or flat? Would this affect the plane's performance? It would be easier to sheet the center section if it was flat. But that is the least of the considerations if the wing needs this diheral built in.

Thanks,
Loren
