I am looking for a reliable, safe, secure and neat way to fit the main hatch on a BVM MiG15.

Currently I am planning on having two locating pins mounted at the forward edge of the hatch, securing into the rear of the cockpit x-brace which is part of the fuselage moulding, then at the rear possibly two of those sprung canopy hatch pins, locating into the rear fuselage section - this however will leave two wire 'lugs' sticking out from the top of the rear hatch, but as I see it there is no rear option here[&o]

The main problem is in the hatch mid-section. The fuselage hatch is long (see pic) and in the middle it tends to flex, and not lay completely flush with the fuselage, so really there needs to be a simple securing system fitted in this area (see close up of area for securing hatch centre section pic).

I have considered magnets, although achieving the correct 'pull' and release to allow securing and removal is a bit hit and miss, I have considered a sprung catch using bent piano wire, locating in a slot cut into the lip on the fuselage top, again not sure on the effectiveness.

Do all you experts have any ideas, I really need something which is 'concealed' and not visible from the outside - any ideas really appreciated.

Marc.
