Please help me with the following three questions: 1) I have tried to do a Gimbal Calibration via the DJI Assistant Software V3.0, but as soon as I connect the Phantom 2 Vision Plus, the option for gimbal calibration disappears in the software. Before the Phantom is connected to the Assistant software I see the option for advanced gimbal calibration where you can set the degrees of tilt. Can somebody tell me why this is happening? 2) I would like to set the vertical angle on the camera a few degree lower down, as I am getting a bit of noise from the gimbal and a red button on the on the slider (in the App) when the camera is tilted in most upright position. As soon as I move the slider down a bit (tilting camera down) the red slider button changes to green and the gimbal noise is gone, and everything is fine. What would be the reason for that? 3) Does waypoints work in the Naza-m mode?
