OKC I think you are missing my point entirely. I know the cub needs the struts. The question has been asked several times on this thread what the dihedral should be on the cub and it has been stated several times that if you build according to the plan the dihedral is set by the angle of the wing tube holes in the center section ribs. BUT when you plug in the wings prior to constructing the struts the wings will droop due to gravity pulling down on them. This is an issue as you need to have the wings in place to set the length of the upper strut fittings. If you just follow the instructions and install the wings and then build the struts you will end up with a negative dihedral. You either need to block up the wing tips to hold them up, or as I found it was easier to flip the whole thing over and just place a small shim under the center section. This also makes building the struts easier as you can access things better. Hopefully that will help some future builder of this model.
