This is a complex single mesh with many parts (destined as a market product).  One particular set of parts is a landing gear, illustrated here.  The first view shows the stowed position with the joint axes visible.  The scale parameters are hidden, but scaling does operate along the z-axis.  Moving along the z-axis (second view)  is off; the part is angled up 4 degrees, but the part moves as if the angle were zero.  The last view shows the strut rotated down before extending; the extension is off exactly as in the previous view. (The other parts of the gear have not yet been rigged, so they are just coming along for the ride.)  This is one of three gears. The other two are rotated along the y-axis complicating the problem.

I have modified the mesh so all three gear and their parts are aligned on the major axes.  I haven't begun this rigging but I should be able to adjust the part positions to correctly place parts and have them operate correctly in the final figure.

It would be great if there is a way to force the parts to move correctly by simply changing the axes.  Thanks for any thoughts.
