I took the Spark to the old park, for some FPV action. I found out first that I needed to turn the sensors off as they would stop the Spark,while flying low. Then I put it in "sport mode" and it was extremely sensitive to fly, but fun!
You did good to be flying in Sport Mode. I would have not used it myself. You were giving the dandelions a hard time. Lol! I like your idea for a landing pad too. Very creative! What app were you using for the FPV experience?
