Hi all,
Does anyone have the experience of time cross quadrotor by using the Lisa M
2.0 and the Aspirin IMU 2.2? 
Last time I finished all the procedures I think including the IMU
calibration then I tried the quadrotor. 
Unexpectedly, the quadrotor firstly span itself and then turned itself over,
causing one of my   propellers broken.
I make sure that I had done all the work needed and now I cannot find the
reason to explain it.  
Does anyone can help me?
By the way, I still have some guesses about it. 
Firstly I cannot make sure that which axis of the IMU should be put in the
front direction of the quadrotor airframe, the x or the y?
Then I guess maybe the magnetometer is disturbed, because it is in the IMU,
and there are so many currents around it. If so, how can I improve it ?
Thank you!
