Hi, Every time we execute Return to Home the I2 ascends to the correct height and start flying back - all great - but during the horizontal flight path back the video,including recording starts rocking left to right - ie jumping as if pivoted in the centre, at about 1Hz - when it starts descending all is fine again. Its not normally usable video but quite annoying as it must be some type of gimbal malfunction which could jump out at another time as well? Has anybody come across this and what to do??
