-10°/10° on a governor in all four flight regimes (Period!)

Straight line pitch curves from -10 to +10, linear, not flatting out the middle.

Straight line throttle curves in normal. “V” curve for idle up.

Make sure your idle up (3D mode) has an increase in RPM, that way there will be no mistaking you're in the 3D mode. Normal 1450, 3D 1850 head speed.

Set your Gyro gain at your flying style. You don’t need a twitchy high gain setting unless you’re losing the tail in backwards flight. Plus this will wear out your tail servo.

Vibration will also wear out your servo and cause premature failure of other mechanical parts.
