On the subject of sequencers, is there a fitting out there that when connected will allow air to pass, and when disconnected, seal off any air from escaping? ie. a check valve of sorts. I have an F86 and need to have the wheels down (inner fuse doors closed) to remove the wings. Problem is that my nose gear remains down and I would like to retract it for transportation. I see a couple options, one is to carriy long air lines connecting the wing to the fuse so that the wings can be slid out far enough to retract the gear before disconnecting the airlines. Not desirable, as then I have extra line that I'm sure will get kinked as it's pushed into the fuse at assembly. The other option is to trap the air in the system when the air lines are disconnect between the wing and the fuse, then the nose gear (and inner main doors) will continue to work as a closed circuit. Any thoughts on this?

BTW, Tom, nice install. Is that CF plate actual CF (ie. Dragon Plate) or is it the simulated plastic sheet you can get? Looks nice.
