I have a theory as to why we’re seeing lots of jello and vibrations in our Phantom 3 videos based on observations of the quad in windy conditions. Windy is the key difference here because I’ve noticed no issues on some days and others it’s been terrible.
At first I thought it was due to unbalanced props as indeed my silver ones needed a lot of work/sanding, especially on the hub as that was quite out of balance. However despite now having perfectly balanced props, I was still seeing excessive vibrations in my videos (see this video as an example):
I decided to closely examine the quad whilst it was hovering in windy conditions, and what is most striking is how aggressively it adjusts itself to maintain position. It makes lots of quick adjustments, and this in turn causes the camera to visibly vibrate quite excessively and wobble on its gimble. I will try and create a video showing this later (no wind at the moment).
Update: From my post below, here is a video of the quad with a wobbly camera. You can see the normal quad vibrations in the legs, and the gimbal dampeners do a very good job to stop those from affecting the camera. However its the quick adjustments the quad makes to maintain position that causes the camera frame to wobble
Ultimately I think this can be fixed via firmware so that the quad maintains its position with less abrupt adjustments, but at a loss off maintaining its position. I recall that my P2V+ used to float around more in windy conditions, and I think that is the difference between the two.
Thoughts?
