Hi fairly new to the phantom 3 enjoying it and this forum very much. But a question I always heard mixed responses to was compass calibrating before every flight. The general consensus on this forum is that it's not needed unless it's out of calibration or mod range or if you leave and are flying in a different ar a than it was calibrated in. I had an issue I needed to discuss with DJI and while on the chat I ask this question and recieved an answer of yes it is recommended by DJI to perform a calibration before every flight. Later in the discussion I brought this up again to clarify and he confirmed it again even if flying in the same area. I know I have read that it could introduce a bad calibration which is a thought but interesting the opinions on this topic. Have read the link on here what the calibration is doing etc. Any other thoughts or comments?
