I have an Autopilotmega, and an IMU with GPS. Air sensor, Xbee telemitry, and video. I am just setting things up and getting everything working. I put everything together, and load the latest code. When I run the GCS I notice that that I get telemetry, but the graphic of the little air plane starts to spin wildly. I take the APM back down to do the CLI tests, and the IMU test reflects the same wild number excursions. Keep in mind that the APM/IMU are sitting still on the bench. I have reflowed the solder connections, and checked them all with a magnifying glass, but they are in good condition. I have also ran the gyro test, and the numbers seem to be fairly stable. I don't know what they should be to tell you that the numbers are correct. Any ideas what is the problem?

    I experienced that problem today, even though it never happened before.  I made a silly move and armed the motors on the arducopter and it immediately lifted its left motor and blanked right and landed upside down, even though the throttle was at minimum.

     

    I found that by disconnecting the sonar the number variance when down to +/- 10 from +/- 200
