Greetings. I'm a novice to the P2 and encountered this behavior that started yesterday. I'm practicing and learning to smoothly takeoff. When I get just enough throttle for it to start to lift off, it does a pitch over towards the battery side and basically goes out of control until I get the rotors turned off. As per the DJI vision assistant; I have the throttle sticks calibrated. And verified I am in the Phantom mode. I have also verified the compass is calibrated, and I have good GPS lock. S1 and S2 are in the up position. Any idea's?
