As a way to check the IMU and compass before each flight, I always check the MC Setting/Sensors page. The MOD values tell you the statistical accuracy of you sensor values. At the end of an IMU calibration, I look for the GYRO and Acceleration (g) to read as follows:
the GYRO: x:0.00 y:0.00 z:0.00 MOD 0.00
the Accelerometer: x:0.00 y:0.00 z:-1.00 MOD 1.00
Before each launch, these values should remain very close to these initial values when the aircraft is level.
The compass offsets gyro procession, it’s bias values are also shown there. The Compass values shows x (north/south); y (east/west) deviations and z, vertical inclination. The MOD value is normally around 1500 after a good calibration. This MOD value will give you immediate feedback if it differs greatly from your initial calibration when you are flying in the same location.
So, what do you SENSOR values look like on your next flight?
