    Yesterday I took my p3a out, check all vitals. Wind was at 7mph.

    Upon lift off the phantom started doing an upward toilet bowl turns. I was unable to control any side to side movement. I brought her down, which was a bit rough.

    Any idea what would cause such a lack of control ? ImageUploadedByPhantomPilots1436823331.756902.jpg

    That usually means you need to recalibrate the IMU.

    Do a good compass calibration also.

    TBE is all compass. Calibrating the IMU will not fix it. TBE means the compass was providing bad data for which there are two common causes:
    1. Taking off from something that has it's own localized magnetic field like a paved sidewalk.
    2. The compass calibration is no longer accurate or was done near a localized magnetic field.
