    I keep reading about imu calibrating. What is the IMU and what does it do. I have a new P3 and am wondering how do I know if it needs to be calibrated. Also if it is needed them how do I perform the calibration? Any help would be greatly appreciated.

    He says after every 10 flights or so??? Is that necessary? I do them after firmware upgrades but not every ten flights.

    It wouldn't hurt anything, but it's not necessary.

    Thank you. Am I correct in assuming that I need to prepare a surface that is non-metallic and perfectly level? Any recommendations on this?

    The surface needs to be level. It does not matter if it's metallic or not.

    Nothing is perfectly level... As close as humanly possible works fine.
    I have done one in the field, sitting on uneven terrain. Certainly it's
    Not recommended, nor by me, but what the hey, eh? Normally a fresh IMU calibration should be done on a chilled or cooled down bird. This time of year is awesome for that cal', early evenings...
