Wavy video

Hi pilots,

Anyone experienced the wavy video like this.? Any idea what the problem, and how long dji can fix it.??

Sort of a jello like appearance? It's from prop vibration. Sometimes a dinged propeller can cause this. See if it changes going forward and backward, and try swapping your props diagonally and see if the waviness changes. If it does, hopefully you can find and replace the dinged prop.

I could probably help more if there was a link to the video, LOL.

OK - this is unusual in that the "jello" is moving vertically, rather than horizontally. I'll stick with my guess that it's due to propeller vibration. A bent motor shaft could also cause this pattern. Would be interested to know if the pattern changes or goes away when the Mavic moves forward, backward, left and right, since that changes the relative speeds of the props.

Is that nothing to do with gimble..?? it get worse when the altitude higher.

These vibrations look to be in the 120 Hz range, since there are several bands of compression and stretching aligned vertically. This tells me that something is introducing a vertical vibration of about 120Hz.

The gimbal is designed to deal with much lower frequencies of a few Hz. Higher altitude will force the props to spin faster, so you would see more "jello" effect.

If the props are not out of balance, another possibility is one or more of the rubber loops that hold the gimbal in position are out of place. Check to make sure that the gimbal is hanging level, everything appears to be in place, and all 4 corners of the gimbal are free to move.

Let's wait and see if someone else chimes in here. There are plenty of people here that know more than I do!

Here's to finding a solution and getting you steady video.

Make sure your gimbal rear mount is under the tab.
