Well it's not exactly a flying car, but...

Try imagining a scaled-up version, mount a turbofan engine, armor it, mount hardpoints on the wings.

Can you armor it and still have it work right? You might get hovermode, but I doubt you'd get flight.

          It pretty much depends on the design specs. If you use similar design specs like the A-10 on this thing...come to think of it..use the A-10 as the template for design. If you can't use the 30mm DPU Gatling as the nose armament, how about a 7.62 mini gun either as an internal fit, a nose pod or hard point pod. You'll need something else to deal with buildings or armor, but it's a good design start.
