This parameter allows to manually compensate YAW gyro drift over time.
## Audience
This parameter is intended for LOS flyers who use the <HEADFREE> feature of betaflight.
It reduces the usage of on sight realignment <HEADADJ>
form 3-6 times to 0-1 during a flight.

## Warnings
Users with exotic board alignment configurations (this feature may not work as intended for your purpose !!!)

The gyro drift depends on many factors, so the results of manual calibration have a big variance
Factors:
gyro (mpu6000 ICM260X ...)
sampling rate
temperature
LiPo (3S ... 5S)
Flight style
Flight time
and many more ...

## Setup
The basic setup can be done on the bench without LiPo (USB powerd)

power on, do not move the quad for 10 minutes
on CW drift 70° --> gyro_offset_yaw = 70
on CCW drift 70° --> gyro_offset_yaw = -70
