Don't think the Electra and C130 were designed by the same team.
Electra was by Lockheed Burbank and C130 was by Lockheed Georgia.
When I did my Electra course I was told to forget anything I knew about the C130 as they were very different airplanes, just similar powerplants. (Didn't know much about the C130 anyway)
Great aircraft though, once the whirl mode was fixed..
