Took the Spark out this morning to a hill near home to see how far away I could get before losing signal, all in line of sight using signal booster parabolic thingies. Flying out of Sport mode, it got to 2500 feet before the battery hit 60%, so to be safe I brought it back. With new battery, and in Sport mode, got to 3,300 feet before signal strength went red and video started to chop up. Brought it back and still lots of battery left to do some circles and other fun things in Sport mode. I'd thought that Sport would use more battery than regular mode, but even with the camera running it did really well. Had to quit playing because the gnats were eating me alive! Did my first hand landing with the controller- having sliced up my fingers on another drone, this made me a little nervous, but all was well.
