ArduIMU V3 Z Yaw Drift with Y Roll

Posted by Andrew Bremer on November 28, 2012 at 1:59pm

I've just got the ArduIMU V3 and have been fighting with it most of the evening - eventually I have ended up using the 1.9.6 version of the ArduIMU arduino program with the ArduIMU Test 

The IMU recognizes all the movement I apply to it correctly, except when I roll it away from myself (the FTDI Cable of the IMU is to my right facing the computer monitor). When this happens, the airplane model rolls as it should do, but the Z Yaw begins to decrease with the Y roll as well, resulting in this situation:

How can I fix this, so that as I roll the sensor away from me without affecting any other axis the Z yaw is not affected? Thanks

    *UPDATE* Revisited the IMU and invested in the correct GPS unit for it. Gonna try it tonight and hopefully it'll work, but I managed to read up that a lot of people have had this problem due to heading drift and air start problems. So I should be able to get it working.....should *crosses fingers*
