I had mucked with the upside-down starfighter before. Its not without its charm and does have a few aesthetic advantages over the normal starfighter - like the six engine exhausts detail being more visible, cleaner forward fuselage (purple front bit), rear tank treads being hidden on the underside (now landing gear/treads), as well as forward and rear facing crew compartments (?, I dunno what to call them). Can even use the front landing skids as a hatch opening (yay, imagination!).
Only thing that kills it for me is the high-mounted wings.
Hexatron is such a good figure to muck about with like that. So many alterations and fan modes!
