The outer doors are hinged to the hatches I cut out and the entire assembly screws into blocks on the wing skins so that they can be removed to service the gear.

There is a tapered plywood piece glued to the back side of the middle gear doors that push the outer doors open when the gear come down. The outer doors rest on this piece when the doors are closed.

There are two small rare-earth magnets embedded in the outer doors and the tapered plywood piece to hold the outer doors closed when the gear is up.

There is an elastic cord between the middle doors and the outer doors that holds the outer doors against the middle ones when the gear is down and pulls the outer doors closed when the gear goes up.
