Thanks for the replies, everyone! I almost never use sport mode, unless it's doing RTH. It was in ActiveTrack mode while the car was being driven at 7-8mph or so. All of a sudden it picks up speed after losing track of the car. In fact, that was the fastest my Spark had flown at that time.
In terms of pilot error, I've flown that exact route back and fourth at least 6 times over 2 days without any navigation issues. I had to stop filming the other day due to high winds. I did recognize that power lines could potentially cause an issue, especially flying with 25-30m of horizontal separation from the power lines. But I wasn't expecting that behavior, i.e. flying very fast and very far.
Active track isn't exactly using GPS stabilization to hold a point or control the flight with pilot stick input. It is using the tracked image to stabilize the flight. Control the drone's flight per what the image is seeing. If the drone is tilted to the max, and flying away at full speed into the ground, but the image looks good to the software,...no problem.
The spark doesn't know the car isn't charging at it and slowly diving underground, as the image it sees suggests, so it tracks it tightly.
Pilots need to be watching the drone to ensure safe flight while the drone's computer does the fancy camera shots for them. |
