Most modern flight controllers enable them by default, but you'll configure the filter count, range, and minimum frequency through your configurator's filter settings to match your frame's characteristics.

Compass calibration isn't typically used in racing drones since GPS modules aren't standard equipment and aren't needed for acro flying.

Fix it by recalibrating sensors on a level surface, checking props and motors, and adjusting PID settings if needed.
