Hi All, just purchased a new phantom v1.1.1 with the H3_2D preinstalled by the supplier. Power the quad up and the gimbal initialises itself and initially appears to be stable. However, If using the Tx I tilt the gimbal thru the vertical (I.e. straight ahead position), it appears to momentarily 'stick' as it goes vertical. If I leave it in the vertical position, it then vibrates, proceeds to go full tilt (camera facing to the floor) and then violently shakes the whole gimbal set up from left to right 5 or 6 times through the full range of movement before going limp. Any Ideas before I send the whole lot back?
