I think you must have missed something on the instructions. I am not sure what you are doing. I have built 2 SSEs and that hatch assembly works just fine. It is a little tough to build but seems to fit fine and is fairly easy to remove. I have an outside switch and charging jack. Because of that and the fact that I never remove the wings, I don't need to remove the hatch often. Friends of mine have located their switch inside and use a magnet to hold the hatch down.
