Could it be a prop' off balance (chipped or dirty/damaged) or a loose mounting plate ?

All motors turning freely by hand ?

Hello Aardvark I have changed to new props, and mounting plates is fine, with no differents.

One oddity I am seeing is with the Draw flight mode.   When I set this up, the bird flies the route, but wobbles as it flies.  It almost looks drunk as it wobbles along the route.  Other flight modes seem mostly normal.

I experienced this too, I just thought maybe my drawing wasn't up to much, so glad to hear the same issue.  Happy Drawings!

Doing some more flying today and while in Tropod mode I lost video signal 3 times while the drone was only 30ft away from me. During this time the Gimbal also went crazy and started pulling hard right. I tried to take a recording, but the drone kept on kicking out of record mode, however, I did manage to catch just a few seconds.  

As you can see right at the beginning, the gimbal is way over to the right and can see it's landing gear.

I've updated with no issues both the P4 and RC.

It did not prompted the "Inconsistent firmware" in DJI GO4 when swapping to another battery that was not in the P4 during the update.
Can anyone confirm that battery firmware is not required for this version?

Thanks.

There are battery updates, run DJI Assistant 2 on PC, and try with each battery, Assistant 2 will indicate either 'Refresh' (If already up to date), or 'Update' (if not already done). Takes about 5 minutes for each update.

This.

I find this quite unclear from DJI's part as it's not mentionned anywhere, unless I missed it.

Currently stuck at 99%, which really p1sses me off as I have done everything EXACTLY as I should have. You would think DJI could have mastered a simple firmware update by this stage!!

No, it couldn't be any of those things. As I noted, the drone was fine before the update (immediately before the update). Same props, same everything except the update.
The update itself caused the shaky flying and I can now see that several others have the same problem.   In any case, it's not a vibration problem. The entire drone tilts violently (wobbles)  back and forward as if it was stuck in multidirectional wind gusts. It also only happens once every few seconds. In between, it flies just fine.
I'd like to revert back to the old firmware until DJI resolves the problem but neither the DJI Go4 app nor the DJI Assistant will allow a refresh of any version other than this latest one.

This is what I was wondering as well.  Every other flight I check the little 'fingers' that push the prop up and if necessary I bend them up to make sure that the prop is tight.    I have not upgraded yet but may do so this weekend.  Work has been crazy busy.     For those who have the HDMI module.. did this update help with the real-time video feedback glitching?    My remote control has the booster on it from Drone World and you would think that with that thing installed I would have signal issues.  I have never lost control of the drone.  The only real problem is the video feedback.  Also, I am using a Samsung 9.7 tablet with my remote.   Thanks and Best Wishes!

I just read over the P4 release notes and no mention in there. But it certainly changes something, after update completed the status shows 'refresh' for each of the batteries. I did notice a comment I think was in the IOS download description, that improvements had been made to 'Smart RTH'. So whether that has any bearing I do not know.

I would hope that the RC update V1.92 should sort out the video glitches where HDMI module was in use. If so then I might consider buying one.

oh yeah, Assistant definitely asks for a refresh when re-booting with a battery that hasn't worked under that firmware and repeated the process over my 2 extra batteries (3 in total).

About to head out for the 2nd battery flight. 1st flight was awesome, super stable under all modes P,A, S.

Draw and tripod worked flawlessly, and had several wind warnings but it is windy today (about 20kph).

No wobbly shaken behavior whatsoever, and gimbal was extremely smooth and levelled, did not have to fiddle with my horizon at all...

It's weird some are having these issues, could it be they are missing the battery refresh?

All I did after the update was calibrate the IMU out of curiosity really and thinking new '3D' process would tighten its accuracy, which it seems it did but on the other hand hadn't flown for months, so perhaps I don't remember.


Edit:Just got back from another full battery test flight. Everything works as it should. With the new working bells and whistles it feels like a new bird. Was confident enough to fly a meter above a river and do some narrow flights under trees lol.

I've yet to try Terrain Follow, might do so later on but wind is picking up....:s

I upgraded my radio first over the DJI Go app before updating my aircraft with the DJI Assistant. Then i updated my aircraft, it was a bit strange than usual but the aircraft restarted a couple of times during the process, it took around 10 minutes but everything went well. After the last reboot, the LED close to the SD card slot and the USB plug stopped blinking between red and yellow and showed a solid orange.

There is definitely an update over the batteries with this firmware.

I noticed with the DJI Assistant that there is actually a minus after the version V02.00.0106-  when i connected my aircraft with a non updated battery. Have a look on my first photo. The assistant also right away proposes you to upgrade.

Around 24% during the upgrade if you look at your battery, the lights have some glitches then the battery reboot and the upgrade goes until the end.

When finished there is no minus after the version installed on the aircraft when you go back to the firmware update tab. Have a look on my third photo.

I also reset the factory defaults settings each times i upgraded my LIPOs. You never know.

I did an IMU calibration then a gimbal calibration. I restored all my favourite settings all over the app.

Tomorrow i will perform my first tests and see how everything perform all along with my all 3 batteries. Wish me good luck...

Thanks AArdvark.

I've used Assistant 2 and upgraded the remaining 2 batteries. Now all show "Refresh" when connected.

Did a VPS calibration and the new IMU calibration. Don't know if will be able to fly today though.

One thing I noticed when turned the bird on it gave me an IMU error prompting me to re-calibrate yet when I entered the IMU menu it showed it was warming-up and all readings where nominal once done so.did not go through calibration.
When back to main screen had a ready to fly mesage, and flight was great.

Same with the second battery, upon powering instead of the warm-up message had the error that dissapeared when the IMU warmed up.

Anyone else noticed it?

For those who are having wobbles when flying, i noticed that the factory defaults settings are slightly different with this firmware. Attitude is something like 50% and brake was something like 70% or more.

It might be interesting to check out your Attitude, brake and even expo and gain values, maybe you should have a look and tweak the values in order to have a better flight experience.

I have indeed a little error every time i power up my aircraft with the app which disappears after warming up, in my case it's the vision system (i disabled everything!), it's maybe just an app glitch...

Yeah turned out that's what it was! So I got it updated successfully in the end.

Just back from some test flights. I didnt even have the chance to try any of these new modes that people are talking about, is there a "Tripod" function now I believe? Don't even know where to find that.

I have noticed that I now receive wind warnings. Don't ever remember receiving those before. Today was annoyingly windy so the app was definitely correct in warning me. I also notice while the drone is sitting with the props at low RPM waiting to take off, the app bleeps at me until I have the drone in the air, is that normal?

Oh, and unfortunately it appears the horizon issue is still very much there with my drone. See attached image.
This leads me onto my final question, is it recommended to do all the calibrations again? My app tells me that nothing needs calibrated so I didnt bother, but maybe I should have?

Thanks.

In response to blackmennewstyl , post 125:-

The sensitivity for my drone (after the firmware update and factory reset) are:
Attitude 50
Brake 100
Yaw movement limit 150

Gain values are all at 100

Expo are all at 0.40 (Normal mode)

I don't recall exactly what they were all set to prior to the update but I believe the above are probably the same.

Tonight (2:30am), I am still working on the drone because I have some commercial work to do on Monday.
All batteries check out as being at the correct firmware level in the DJI Assistant (it shows the "refresh" rather than "update" for all four batteries).
The DJO Go4 app also says current firmware when starting up with each battery.
Tonight, I have totally refreshed the firmware; this time using the DJI Go 4 app (I used the DJI Assistant yesterday).
I'm hoping this refresh will change things with a test flight tomorrow but I'm not overly confident.
At the moment, the unstable (wobbly) flight characteristics  make it virtually impossible to use (other new functions like landing, gestures etc all worked fine after the update).

The sensitivity for my drone (after the firmware update and factory reset) are:

Honestly, attitude at 50 is pretty low and brake at 100 is way too higher for my taste!

Before the upgrade my attitude and my brake values were 80 both.

My Expo values were 0.5 for throttle and 0.20 for the rest.

My gains were a little bit more higher than 100 except for YAW, i tweaked them a lot before finding the values i like and especially for VERTICAL.

I will probably have to do the same is the new firmware changed the flight characteristic of my aircraft.

Tomorrow i will perform a couple of flights and i will definitely report if i face some annoying experiences.

Hi all,

RATS... I have to join the crowd.  I was able to successfully update everything (DJIGO4, Firmware on both P4 and RC, Assistant 2, and all batteries).  Went very smoothly (and I carefully documented every step which I will share soon).

I did a test flight, just a hover (about 10 - 20 feet up) in my back yard and a bit of back n forth and side to side.  I can say 100% that there is a problem with the stability of the bird that did not exist previously.  I will videotape with my phone on my next flight.  I can hear one or more motors "surge" randomly, as if I pushed the throttle for a quarter of a second and only affected one motor.  The result is uneven hovering and flight.  As if someone is thumping one of the corners of the drone, causing the drone to buck.  You can hear it in the motor, and see it in the flight.  Spinning the bird during hovering in place really shows the problem.

Here is a 60 second video which shows the problem with the SUBTLE bucking of the P4 after successfully completing all update, IMU and Compass calibrations, etc.  The motion is random, appearing only four or five few times in the 60 seconds, and the prop sound blocks a bit of the more obvious high pitch sound that also happens when bucking.

The bucking is enough that the gimbal can't compensate quickly enough so it ruins any video I might be shooting.

There was a subtle breeze, not anything any of us would consider an issue.  Though I will say that it appears the problem is a bit more obviousle when the bird is being pushed by the breeze, as well as when it is in flying in any direction.  I didn't touch the sticks once during this video.  The ground is asphalt and plenty bright, with plenty of debris on the ground for the VPS to grab onto.  I set the exposure to the white P4, which makes the rest of the frame look much darker than it actually is.  Plenty of light and texture for the VPS to work.
This problem appears to be as evident at 50 feet as it is a 5 feet.

In your video the drone is hovering quite close to vertical obstacles (garage doors, trees etc?). Could it be that the obstacle avoidance system is trying to correct for proximity?

Does it do it do it indoors/no wind at all? To me it looks like tiny adjustments the drone does to stay in place...I thought I would be seing the thing screaming and moving erratically.

Hi guys... I've now done four test flights, at times in a stronger breeze, and other times when there was no wind at all.  
Some of the floating in the video is because of the gentle breeze, but the "bucking" isn't because of wind.  The wind is very gentle (look at the loose leaves sitting on the ground, and look at the shadows of the trees on the asphalt, nothing moving).  The bucking isn't huge either, but it is a brand new problem and it shouldn't be occurring.  I've been flying this thing for a year and know it very well.  This problem only started today, after updating the software and firmware.  I can also hear it in the motors, a somewhat high pitched sound that occurs when the thing bucks.  If you listen closely you can hear it.

Anyway, I have been flying this bird in a HUGE variety of questionable circumstances including high wind, bitter cold, dense fog, high altitudes, skimming just above the water, and way more.  This problem is new, plays subtly in the video, but anyone who really knows their bird would see this difference.  It feels.... broken.
UPDATE:  I also notice that a gentle breeze pushes the P4 WAY off course as it flies in straight line.  Instead of the drone tilting slightly to hold its position, it drifts.  I actually thought I might have switched to ATTI mode in the way it drifted.

Hi Moshe, maybe it isn't as bad as it can be, and maybe I'm lucky because of that.  But it still shouldn't be happening at all.  I won't be able to use this for my professional video work until it is fixed.

My installation experience.....  (Apart from my previous post ).

On my first flight, the craft performed normally.  But, the video was dropping in and out at 30 - 40 feet.  I was getting green bars and freezes.

But, this 'stabilized' after a few minutes and I was able to fly normally.   One thing I was getting were high wind warnings.  They popped up on the screen in red text advising me to stay close and in sight.  Thing is, that there was hardly any wind.

When I first got my P4 about a year ago, the horizon was very wonky.  Over time, it 'wore in' and now it's not bad.   Sometimes when take off, it has some tilt, but if I fly around in a few directions it levels out.  I was worried the update might set me back, but it didn't.  My horizons are still acceptable.  

Otherwise, no complaints.   Thanks DJI
