Jan, I believe there's a hydraulic arm that runs upwards from the center of the linkage, which is how the two doors actuate in sync. Vertical motion translates into opening and closing via the contraption.

Mwaw..... don't think so, Carl. Here beneath you can clearly see the boatlike apperature where the upper folding strut will fit into once the gear is almost up into the bay. With the final movement of the gear the upper strut, now resting on the boatlike apperature, will push it upwards so that the two vertical 'latches' pull on the doorhinges henceforth closing the doors. Also attached to the two latches you can see the springs that pull the doors open once the upper folding strut has left the boatlike apperature upon deploying the gear. No hydraulics needed.. Pretty neat, huh.. ;-) ( to deploy/retract the gear there's only one small hydraulic cylinder that can be seen clearly in the model screenies)
