Hi,Received my Inspire 1 Raw Today but its not hovering perfectly.Its move like 10 - 15 cm on each side.If i should do IMU and Compass Calibrate,Can anybody give me a perfect way to do? (Can i calibrate IMU in Aircondition room?)

IMU calibration can be done anywhere. All that is required is a flat, level surface and that there be no interference while it does it's thing. (No vibration, or movement of any kind.)
Note also that the specs are as follows:

Hovering Accuracy (P Mode)

Vertical: 0.5 m Horizontal: 2.5 m

In addition to an IMU calibration, have you calibrated the compass? What kinds of winds are you flying in?

Were you able to resolve your issue?
