Good work: especially to get electrical power too.

Why does the B-25 have a noticeable dihedral from the fuselage to the nacelle only to go flat for the outer wing?

Here's your answer>>> ref.

"Early into B-25 production, NAA incorporated a significant redesign to the wing dihedral. The first nine aircraft had a constant-dihedral, meaning the wing had a consistent, upward angle from the fuselage to the wingtip. This design caused stability problems. "Flattening" the outer wing panels by giving them a slight anhedral angle just outboard of the engine nacelles nullified the problem, and gave the B-25 its gull wing configuration."

I believe that the B-25 "Miss Hap" was one of those first nine and had the straight dihedral wing before being modified.
