The Ardupilot manual keeps saying to adjust the Servo PID gains, but shouldn't servos be fast enough to respond these days without gain tuning?
What is the difference between Mission Planner's Nav Roll PID, Nav Pitch AS PID, Nav Pitch Alt PID and their Servo PID counterparts? Shouldn't gain tuning involve the Nav PIDs more so than the Servo PIDs?
Does this have something to do with how the cascaded PID loops are set up? I still haven't been able to picture what the APM's cascaded PID looks like.
