Well, after some more flight time, the autel could use some improvement in the stoping distance. Also, had a bit of a crash tonight. After flying around for about 15 minutes, showing it to some other people on a job site, I called it home to show how it lands. Then after it landed, I fired it back up and this time took off manually. I lifted up to about 4' and hovered. Then decided to fly low and fast. But, as the ground moves away from the building, it rises slightly. Probably a total rise of about 8'. It travels faster in a forward direction than it will climb. The landing gear clipped the ground and flipped it. Doesn't look like it hurt anything other than my pride. got the gimbal a little dirty. But I made another test flight to make sure then packed it up.
