The latest kit in the Real Grade line isn't a Gundam but it definiltey belongs in that group.  The RG Skygrasper is an amazingly detailed 1/144 kit of the lovely spacecraft and also comes with all parts needed to make your Aile Strike Gundam (sold separately and linked below) into the Sword or Launcher Strike Gundam.  The same amazing level of detail and engineering found in the previous RG Gundam kits is here full force in the Skygrasper.
