I like composites, but that seam turns me off . Even though you can't see it at twenty feet away I still know it's there. The other thing is the noise they seem to generate. The sound of the hatch rattling and the servo wires vibrating inside the wing gives me a headache.
. You have a set of cannisters and then you hear all that racket. It just doesn't do justice for the plane IMO. If I ever have one I would surly do something about that.
