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