PID Tuning

The process of setting the control loops which will tell an autopilot / flight stabilizer / flight controller how to null out undesired fluctuations. Get these wrong, and either oscillation or inadequate control to deal with turbulence will result.

Often used with a balance jig to tune before flying.
