Fifty questions on the control system — what the flight controller is actually doing, how it turns unreliable sensors into a usable estimate, and what happens at the edges when it runs out of authority.

Six themes: instability and fly-by-wire, sensor fusion and state estimation, control loops and tuning, the mixer and motor authority, filtering and latency, and failsafes and autonomy. Pitched deeper than the flight-mechanics quiz: this one is about the control system rather than the aerodynamics.
