Hi all.
So I went out and tried the latest Litchi 2.5.1 for iOS together with my Spark (FCC modded) to test out the function Waypoint Mission.
I have previously used Litchi with waypoints on Phantom 3 Professional and Mavic Pro with quite good results. (The only thing not working optimal with the Phantom 3 was that a Cinematic Shoot which had to decelerate from several different speeds to a full stopp gave a little jerk when it came to a halt. I could overcome that by manually adjusting the speed while it went through the waypoints).
But now I was curious how the Spark would manage a WP mission.
So I went out on a small field, started the app, pressed "Cancel" on the Region change dialogue box, keeping my FCC mod. Then I drew a quick random route making it turn in all kinds of directions, and I put down a fixed Point of Interest in the middle of the field which the camera had to face at all times. This meant that the Spark would have to rotate constantly while traveling to keep the camera positioned at the POI.
So I started the mission, and all the functions seemed to work fine.
However, when looking at the result (file from the SD card), I was a bit disappointed. The result were quite jerky motions through the waypoints (remember the Spark is constantly rotating to keep the camera at a fixed point in the field). It was worse than I am able to fly manually. Perhaps a straight line or waypoints without any yaw movements would have worked fine, but this "stress test" I did was not satisfactory. I don't think Litchi is to blame, as I get the same result with the modded TSS app giving the Mavic capabilities to the Spark. That modded DJI Go app also gave the same jerky movements. So I guess it is fair to conclude that this is the lack of a three-axis gimbal that gives these limitations. Probably also the reason why DJI has not implemented waypoints into the functions of the Spark.
