After successful calibration of IMU it is noticed that the camera tends to shift about 5 degrees to the left momentarily when I start up the P3P by pulling back both throttle sticks in the usual manner after which it returns to the original state of facing the front again. At same time also noted that this happens whenever I push the left throttle to either left or right and the camera shift momentarily in that direction. however it always then returns to the original state of facing the front. I followed up with a complete throttle calibration and yet the issue sustain. As the weather is not favorable for me to test the drone after these calibration I wonder what may happen once it takes flight in the air. Keeping my fingers crossed that all will be well. Anyone help much appreciated.
