I was just out testing a camera mount by hovering just about 5'-10' off the ground in a hover. I waited to take off until I had green lights. Upon starting the motors, the front lights went red and the rear green. So far so good. I lifted off the ground into a hover to make sure everything seemed right. While it hovered, I noticed the green flashing light kept flashing yellow every now and then. Maybe 5-8 green flashes then 2-3 yellow. I was only in the air for a few minutes but it did this even after I landed. Any help?
