Tonight when I went to fly, my standard kept acting like it had no power. I did the auto takeoff and it barely went 1 foot up. When I raised it up it kept acting like it was having a hard time maintaining altitude. Kept wanting to drop. I had 10 satalites, calibrated it before I lifted off and had fully charged batteries. Any idea what could be going on? I did a IMU calibration and tried again with the same issue. Only went up a foot then dropped down and flipped over.
