This is the story about our brand new FIMI X8SE that has bad video image stability. Despite the firmware updates and careful full gimbal calibrations the flights still produce wobbly and shaky images. The take off point is solid and the gimbal at start up is clear and not obstructed in any way. The wind is very low <10 and I am flying smoothly. I have carefully checked all propellers and have swapped them around.
What ever I try does not solve the fault. I have tried gimbal gain settings from 10 - 70 as advised by FiMi support but every time I get to a near acceptable video the next day its all different again and I am wasting half of my flight time fiddling with the gimbal settings to get a nearly steady video. Some days I can get a short piece of video that is acceptable only to find that a minute later the wobbles start again.
The first video below looks very good and take off from concrete and no obstruction for the gimbal movement appears to be a very promising video - however minutes later it all goes wobbly.....
The second video below is going up 35 metre and the car park wobbles are horrible. The gimbal is failing to stabilise the image being recorded - very sad.
I have sent request to FiMi for help and advice and I am waiting for their reply ((24 October 2019)) further communications are in progress since this date ((November - December 2019)).
I have received advice from FiMi Support about making adjustments to the Gimbal Parametres
Video 3 below shows the result after the adjustments and although a misty day here in the UK we can see a steady and smooth video
The video has been downsized for the website although you can clearly see that the jello effect in seen in video 2 has gone for a while in video 3
Since then on the next flight the jello problem has returned and again changing the Gimbal Gain seems to settle the wobbles a bit for a while
Then they return and are still there and I am at a loss what to do next ?? FIMI what are we going to do ??
We are in close contact with FiMi they helping us with our problem. FiMi Support are very good response and are very helpful. We have sent good video and photos for analysis and will be letting you all know Latest updates when available.
Our quad has been sent back to FiMi although with UK Christmas and New Year we will not concern until 2020. Also note that China is closed for most end of January for their spring new year celebrations that go on all week so no business happens then!
See you all again in February 2020 -
February 2020 we have now received a replacement quad from FiMi and have tried a couple of test flights that have been very good with all systems working well.
March 2020 - Here in the UK Lock Down - Stay at Home - rules are now in force and we are grounded with batteries in storage we look longingly out of the window and hope that we can all remain safe until next year when we can hopefully enjoy some more flying around.

Take off from Concrete Slab ->
Wobbly Car Park ->
Jello Effect Gone after applying FiMi Instructions ->
How to Adjust Gimbal Gain ->
In the above video we see some Jello Wobble effect in our video feed and so we make adjustments to the Gimbal Gain to steady the image. It has been suggested that different temperatures may affect the settings applied and therefore on a hot day opposed to a cold day the setting of Gain may be different and further calibration be required to suit your location. If this video has helped you then please let us know. It may help if you would tell us the manufacture date of your drone body and what setting % you found to work best for you and the approximate temperature of the day. We will try to decide if there's any relations ship between the data in the future and we will let you all know here......

Try these settings or similar for your self as you may be able to fix the problem.
Fimi Notes not in the manual
The constant beeping indicates that the RC needs to be recalibrated. So you need to connect the remote to the Phone and start the fimi app. Then you need to go into the settings and tap on "calibrate Remote" .. Then you need to wiggle all sticks and then its done. Left Stick Up-centre-Right-centre-Down-centre-Left-centre and then do same for Right Stick then you may be asked to move the left gimbal wheel all up and then all down follow on screen instructions and when success - well done - job done!

Part of the update process involves the copy of the compressed .bin firmware update file that uses the SD card to unpack itself and install then to the drone. All this happens automatic and us users just download and install making sure all components are on and connected. When the update process failed for me at 50% I was advised to try a different SD card and that did solve the issue for me. All updates installed perfectly. You must use top quality genuine memory cards. (credit:hackra)
Advice received about the jello effect
Make sure all propellers are in good clean condition not causing vibrations. The Retaining screws are firm.
Take off from solid level surface - make sure gimbal is clear to calibrate itself.
Please check the gimbal cushioning ball (requires the customer to prepare and change it himself), which can improve the situation.
FiMi Support advises that Our engineer watch the video provided by you and he still suggest you to adjust the gimbal sensor parameter from 10-75.
Could you please try to do that again?
Setting-->gimbal-->advanced settings-->gimbal gain.
Please adjust the gimbal gain parameter from 10-75
Its quite normal for your motors to feel warm after flying. If you can hold them without discomfort all is well. Only concern should be the motors that feel uncomfortably hot to hold then further investigation may be required. You should know if you have been driving them hard. Its also normal to find that the front pair are cool and the back pair are warm. If only one motor feels more hot than all the others then further investigation may be required. (Credit:Bardwell)
Sometimes the sky is very bright and the ground where your subject is may be dark.
A quick fix is simply to touch your screen where you want the correct exposure to be, an open padlock icon will appear at that spot and the camera resets its metering to that location.
Should you choose to have the exposure continue then double tap and you will see the padlock icon is now closed and the exposure remains at that level.
If you see "Low Speed Warning" relating to the write speed and saving of your 4K videos then you should first suspect the memory card that you have installed. The sustained high bitrate that the 4K video uses will tax any memory card to the max. Most memory cards are totally unfit for the purpose and should you have a fake memory card then problems may occur. The memory card when it gets old will begin to fail and all your data may not be saved. The memory card recommended to us many times is the SanDisk Extreme UHS-I V30 U3 A2 this is probably the best for the money at this time. Beware of fakes as they are everywhere so buy your memory from a proper reputable dealer to get a genuine version. One should also note that memory cards do not last forever and after a certain number of reads and writes will start to fail at some point. Buy a couple of 64gb cards rather than than one 128 GB and swap them around just like you will do with your batterys and this should give you best long term service. Formatting on a pc involves fat32 if memory is less than 32 GB and exFat if over 32 GB. Why not simply format the card in the drone from the app before you fly?
