No way Vanko was a scientist/engineer just like his father as well as a hacker that why he broke into Hammer's database like a piece of cake,while Hammer was standing there like a fish taking a breath.
As to linking the drones to his armor was also a feat of genus of which Tony will implement in new armor models.
Remember the movie-verse is our reality combined with tales of global threats that our heroes have to solve or defeat.
I love the suitcase armor it harks back to the 90's animated series I own a action figure of the Tony Stark with the case and parts of the armor.
That's my take.
