Are RcAileron, RcElevator, RcGyro, RcRudder all outputs- e.g., basically commands sent from the drone to the motor, or are those indications of how the stick is being pressed?

Are you talking about the outputs of the RC? Could you please post a screenshot or a short video about this? Normally, you'll be able to see how the sticks were being moved if you replay the flight records.

I'm talking about the flight logs. When I export and analyze them, I see those fields.
