>>7970672looking over the back of HFTD Starscream, I can confirm the TDF back storage hole is shallow compared to it. The double hinge piece attaching the fins to the back plate is also gone, down to a single hinge. The double hinge allowed the fins to fold a bit flatter to the body in robot mode. And the 2 sculpted in lines on the fins, beside the swivel hinges, are gone.
Very odd mold changes since they seem to have not touched anything else but the lack of double hinge doesn't affect much. The shallow hole does though.
However comparing photos I can say the details on TDF are much, much sharper as if they went through and cleaned up every edge in the process.
