I have a number of drones, larger than the Spark but am very impressed with Spark's performance and features. I do photography and view Spark's photographs and videos to be at a very good presentation standard. Messaging at this level is more effective than number of pixels. With warmer weather now, I would like to fly the Spark from a moving boat. I once did this but the signal got lost a number of times as the distance between the boat and me increased so I returned the boat to its original location to regain the controller-Spark connection. I would like to fly the Spark behind the boat, on the side of the boat, in front and even away from the boat while I am cruising fast around a lake/river. So the question is how to do it this: If I tap my Home position (on the Go 4 app) periodically while the Spark is following me in the boat, will this allow me to fly it without distance restrictions? If I use the Dynamic Position do I need to be in Active Tracking mode for the software to automatically update my Home position or this is not even an option. So manual or automatic? Are there other options? I appreciate any input to learn. Thanks
