 What might the black pieces hanging down and back for?

Hellfire missile hard points. This is an insurgency fighter. It can sit up there for hours, at 50,000 feet over the battle field, out of range of shoulder fired ground to air missiles  and carry more hellfires than a predator.

This is just a scaled prof of concept. The final product is two place side by side and much larger. It may have a turbo compound engine if they are smart.
