I am happy to share a CAD model of the Turnigy Talon Hexacopter airframe (available from Hobbyking), to be used for our integration purposes. It can be found here: http://grabcad.com/library/hobbyking-turnigy-talon-hexacopter-frame. It should be fairly accurate, but please report any problems you may find.

I am planning to release more models once I am progressing with my hexacopter design here: http://grabcad.com/fiepel-1.
