Our flight time is around 10min, so I couldn't observe a drift at this short interval.
After 10min. flight we land and change the battery, therefore the sensor starts with a different offset value. Thats our problem.
Now I removed the initialization line and made it constant (1558 for my sensor), which I measure indoor. I also calculated the scale and offset values using the samples which we took by car. I will try these tomorrow.
According to the codes, the sensor initializes at power on. Therefore, I don't understand why your sensor drifts in flight.

Do you find your ETS airspeed sensor is drifting, or some other problem? I seem to be having a similar issue, today ours drifted by ~5 m/s in ~1 hour. E.g. after the hour it would report 1 m/s heading into a ~6 m/s wind, 2 m/s heading into 7m/s wind, 0 m/s heading into 5 m/s (or less) wind.
