[SOLVED] rotation around horizontal axis

[funkysf]

When operating my crazyflie 2.0 from the android app the device spins slowly around its horizontal axis which makes it almost impossible to control. Can I assume that the crazyflie should be relatively stable with no movements except thrust?

Can this be a prop imbalance issue? Unfortunately I have no crazyradio usb interface yet, so I can't observer parameters when flying. However, when I connect the device via usb I can see in the parameters tab that the HMC883L row under "imu_tests" is marked red. Does this mean something is broken? The self tests obviously finishes successfully and the messages in the console tab don't indicate any problems. The pitch and roll readings on a level surface are (-0.22 pitch and -0.70 roll).

Thanks!

False alarm, sorry! I mishandled the yaw control. Don't know though what to think of the red column in parameters tab... Thanks anyway!
