I notice when recording that the footage is shaky tilting left and right occasionally. is this normal? Or does changing to FPV mode solve this weird shakyness? This bird is awesome, flies flawlessly but my only complaint would be this. And one more question. Is it normal for the foam on the controller mobile device holder where you slide on your cell/tablets to be always "dented in"? Because I just realized that one of the pads below seem dented in and was thinking if it would affect anything in future such as the foam tearing out, etc especially after repeated use.
