Funny thing this, I have been chasing an issue (X gyro drift) in my arducopter lately. I took out the board and hooked it up to my computer via usb to look a look at the sensor raw values in AMP while manupilating the board (APM/Oilpan) in various directions. When only moving it in roll (X axis) only the values gyro X and accel Y seems to correspond. In pitch (Y axis) Gyro Y and accel X seems to make sense. Is this a bug in AMP? or in the AC code? (1.0.76 and 1.45B)
Anyone else noticed this?

I have seen three roll issues posted in the last few weeks. One was a vibration problem. The other, more likely, was a problem with the sensors becoming lose from the PCB due to impact, vibration, or whatever, over time. There is a good video of this on the discussion. If it is just one axis, I'm inclined to favor the bad contact issue over the vibration issue.

Hope this helps. If you read my replies, then you'll know I've given you everything I know and them some, so feel free to skip over my unintentional misleading theories ;)
