Some might remember the thread I started a couple weeks ago about my H crashing in CCC mode. In that thread, the consensus was that if you go from 1 waypoint to a 2nd, then climb rapidly to a 3rd, it will dip down sharply between 1 and 2 to curve the line on the way up to 3. That conclusion was borne out by testing.
Well, that's not ideal, but it's at least understandable. Further testing today, though, leaves me thinking the CCC logic should have been better thought out. I decided to see what would happen if I started at one altitude at waypoint 1, then went straight up to 2, then farther up to 3. So unlike the last time, there would not be several waypoints at the low altitude before transitioning to the higher one. The transition would happen immediately from the start.
So the way (cinematically) this should ideally work is that the drone moves into position for 1, and then when you push the left stick forward, head straight toward 2, and then 3.
What actually happened is that it curved the vertical again, even though there is no "curved cable" reason to do so because the starting point of the cable is also the start of the climb. For a smooth "curve," it should start at 1 and just go straight up. Instead, it dropped 8 feet very quickly. I was starting to flick the abort switch when it went back up. But you can see in the video that, having started at 18 feet (over a ditch), it got close enough to the ground to blow some leaves around.
The really dumb part is that the "curve" part wasn't even smooth, eliminating the point of putting the curve in at all.
Anyway, I just thought I'd post this in case anyone else was planning on doing altitude changes in CCC mode. If you do, be very careful, especially if you're going for the crane shot.
