Finished unwrapping.

Even though I had seperated the unwrap to the mechs component parts, it took me the best part of 8 hours to manpiulate, cut and sew as well as re position the uv's into a nice texturable shape.  After this endeveour I felt very pleased that I managed to unwrap this mech and keep everything on one UV plane.  Usually I would have used 2 or 3 for my smaller models which is not what happens in the game industry.  Below is the final what the final UV unwrap and repositioned looks like.
