New battery is full charged, The bird has been working well until now. Mode 1 and throttle stick is at left. After Calibrate and power up, there is not enough revs for lift off. Nothing has been changed in the DJI Go app or on the RC. I bought this PH3Pro at Xmas - a few months ago and i has only done in total, 4 hrs. Any idea what could be the cause of not enough revs to take off?
