I don't know this particular unit, but in general all the MEMS gyro/accelerometer devices have too much long-term drift to be of much use. Gyro drift rates of xx deg/hour (with xx being a 2 or 3-digit number) are the norm. They are great for aiding GPS when a vehicle is in a tunnel, or firing air bags on rapid decceleration, but they don't do much for our needs for inertial nav.

IMHO, It might be useful to fly one to measure the 3-axis kick vector during a motor burn, and/or perhaps for helping to measure the instantaneous angular velocity changes when magnetorquing.
