A quick disconnect for what? If you are looking for an easy way to attach the hatch cover that can be removed quickly, use rare earth magnets. I have used them on everything from electrics up to a 1/6 scale .91 sized Biplane and have never had one fail. They hold like crazy and can be removed easily. You can get them at Radio Shack. If that is not what you are asking about, then disregard!
