Thanks borg - I suspected as much. I may still use the IMU as a back up and for calibration.

We want to fly a camera over a football pitch using the IMU to show camera orientation (pan, tilt and roll) and x/y/z position. We will have as much time as needed to set up and the camera will be stationary for may seconds between 'shots'. My question is can I trust the IMU positional data or should I stay with counting steps on the stepper motors to estimate the position.

I am looking forward to using the IMU brick in a motion control application. What is the positional accuracy using an IMU brick using Quaternion math? I realize that the 32 bits of data is more than I need, but am more interested in the IMU's ability to find itself in 3D space from a set starting point.
