Are you sure the faces are connected to each other ? Did you export via .3ds to .max and than reimported back to blender ??? Check if there are no doubled vertices in your mesh and that all faces are connected to each other !!!! If this is not the case normal recalculation will fail !!!
For example: Select one wing part object, select all faces (A) in vertex mode and click W, than remove doubles. This function will join overlapping vertices (or vertices which are near each other) you might not see. Blender will tell you if vertices are joined or removed.
The limit and threshold of joined vertices you can adjust in the editing panel under mesh tools. Than recalculate the normals again.
