The lower hull is completely new. Initial prototypes were based on an altered A6 hull, and that’s where the problems began. The Panda kit was based on a prototype, and no one seemed to notice.
If you haven’t seen this, it’ll get you started.
Main deficiencies:
Duke box missing tone of detail - vents, hatch
Missing radiator filler hatch on engine deck
Underside is ficticious save for the two triangular portions
Rear hatch opening has the wrong shape
There should be no holes for the spade mounts (left over from original prototype)
Roof details wrong in many areas. Roof hatch on left is ficticious.
Missing semi-circular access cover on engone deck
Driver’s Enhanced Vision unit poorly detailed
That’s a start - not just a few misplaced bolts and misnumbered parts in the instructions.
