Dave,

That is very similar to what mine look like - in that the hinge is setback well from the edge of the opening and the door doesn't open too far. Even so, you have a fairly small effective lever arm to move the doors closed.



Now image if the doors were mounted with the hinge line closer to the opening (more to the left in the photo) and the door was allowed to open more. First, the door ram would actually be touching the side of the wing skin (I've seen that in an installation), and the lever arm would be even smaller.

So what I did was make a (slightly) modified door hinge that puts the ram piston attach point further out and down into the wing when the door is open. Likely not necessary, but I have *very* positive door closing leverage that should be able to overcome almost any air flow... Just a bit of insurance and I figured that while I was at it, why not?
