My spark crashed and front left motor stopped working. After cooled down, motor began to work, but both front motors are little when they rotate compared to rear motors. After that, flight wasn't normal. Hovering in GPS flight is not normal. Even in normal wind, Drone is not stable. It moves and turns in normal wind. Then front led lights turned off suddenly. I didnt take pic or started video. I tried to restart, then front leds started to turn on and gone suddenly. Flighting is not stable at all. It shakes heavily. Please help!
