Well Crash Master, VF quote ' The gap between the wing root rib and the fuseledge side has been eliminated from the top side by curving the TE inwards to match the fuseledge contour. However, there may be a small gap on the lower side of the seam, and we have not been able to get to it yet' So sounds like they just about goit it licked. I like a company that belives in continuous impovement. I wonder if they have any other products in the works.
