Here is a quick sketch of the left wing attached to the mostly drive-train. I can play the animation in Blender to experiment with how it moves. I am making adjustments to the wing armature, experimenting with different angles and lengths to get the range of motion that I want.
Before adding feathers, I will finalize the main structural components of the wing. I also will add structure to the gearbox and the mechanisms, such as the linkages, that make the wing move.
