There’s a new issue affecting some of the latest DJI O4 Pro Air Units, and it’s something FPV pilots should know about. A manufacturer recently reached out to me and pointed out that the latest batch of the DJI O4 Pro appears to have changed design internally. More specifically, it is now using a different gyro chip, and that change seems to be causing major problems with footage stabilization.
Further readings:
What’s Happening?
In simple terms, DJI have made several changes to the 2026-production O4 Pro Air Units, including a different ICM gyro. For some users, stabilization is no longer working properly.
The raw, unstabilized footage still looks great, but once you try to stabilize it using RockSteady or Gyroflow, the image starts to look terrible: jittering, shaky, unstable, weird movements, and sometimes almost unusable.
Apparently, this is the same gyro used in the DJI O4 Air Unit, which is known for being more sensitive to vibration and causing headaches for pilots trying to get clean stabilized footage.
Here’s a close up picture of the Gyro in the original DJI O4 Pro: MP66 (MPU-6050 gyro chip)
Here are some close up images of the Gyro in the new DJI O4 Pro from 2026: 1469D (ICM-40609-D gyro chip)
And here’s a close up picture of the Gyro in the DJI O4 Lite: 1469D (ICM-40609-D gyro chip), you can see it’s the same chip in the new O4 Pro.
At this stage, it’s not clear why DJI switched to a different gyro that has been known to be problematic. It could be due to supply chain changes, cost, availability, or a silent hardware revision. But whatever the reason, it is clearly causing problems for some pilots.
I want to make it clear that I personally haven’t had this issue myself, I’ve used one of these O4 Pro with new gyro in the Firefly25 and it worked absolutely fine.
But over the past few weeks, I have been hearing the same complaint again and again:
“Why does my O4 Pro footage look perfectly clean in the goggles, but shaky and terrible in Gyroflow or RockSteady?”
That is the key symptom.
I have spoken to a number of manufacturers, and they also confirmed that this is a known issue on their side.
Of course, not every shaky video is caused by the new gyro. You should still rule out the usual suspects first:
- bad PID/filter tune
- hardware problems like bend props, damaged motors, or loose screws
- poor soft mounting for camera
- too much vibration in the frame
- ESC settings such as not using 48kHz PWM
- lack of power filtering capacitors
But if you have already checked all of that and your footage is still stabilizing badly (while your live view in the goggles looks fine), then the new gyro in the O4 Pro is a likely cause.
Which DJI O4 Pro Units Are Affected?
Based on what I’ve been told so far, if your DJI O4 Pro was produced or released after February, there is a good chance it might have the newer gyro chip.
That does not automatically mean it will definitely have problems, but the risk seems higher.
How to Check If You Are Affected
Without opening the camera housing and physically inspecting the gyro chip, the easier way to check is by looking at the production date.
You can find the serial number:
- on the product box, if you still have it
- on the Air Unit itself, at the bottom of the white sticker
How to Decode the Production Date
My new unit has a serial code like this: 9F2KP 2B001.
After the 9F2K prefix, there are always 3 characters that encode the production date.
- 1st character = year
- N = 2025
- P = 2026
- O is skipped
- 2nd character = month
- 1–9 = January to September
- A = October
- B = November
- C = December
- 3rd character = day
- 1–9, A, B, C… represent consecutive days
- O is skipped
For example, for 9F2KP2B001, decode the 3 letters in the middle – P2B which would be 2026 February 12th.
So by decoding those three characters, you can work out when your O4 Pro was manufactured.
If you have an affected unit, I’d be very interested to know your production date. Even if your unit is not affected, please share it. The more data points we collect, the easier it will be to narrow down exactly when this hardware change started.
Potential Solutions
I really hope DJI addresses this soon, perhaps with a firmware update, change the way gyro data is processed maybe. Since the issue seems tied to how the gyro data is being handled, there is at least a chance this could be improved in software.
Until then, here are a few things worth trying.
1. Update Everything
Make sure you are running:
- the latest O4 Pro firmware
- updated goggles firmware
- the latest version of Gyroflow
You want to rule out software mismatch first.
2. Try Both RockSteady and Gyroflow
Try these stabilization separately and see which ones work.
That can help narrow down whether the issue is:
3. Improve Camera Soft Mounting
I happened to have one DJI O4 Pro with the new gyro (produced in 2026 February), and I tested it in both the Flywoo Firefly 20 and Firefly 25.
Interestingly, on both of those quads, the stabilized footage and raw footage were absolutely fine — no jello, no visible vibration, no major stabilization issues.
That strongly suggests the problem can be worked around. A properly designed soft-mounting platform for the camera seems to make a big difference.
So if your footage is suffering, one of the first things I would look at is how the O4 Pro camera is mounted in your frame.
Check out how Flywoo mounts the new O4 Pro in their frame which seems to work really well: https://oscarliang.com/flywoo-firefly-25-mini/
4. Try Other Settings in Gyroflow
- In Gyroflow to set integration method to Complementary
- Another thing you can try is enabling a low pass filter in Gyroflow, for example at 5Hz.
This may help smooth out problematic gyro data and improve stabilization results.
It is not a guaranteed fix, but it is definitely worth testing if you are affected.
5. Check Your Build Carefully
Go through all the normal vibration checks:
- props
- motors
- screws
- camera mount
- frame resonance
- PID tune
- ESC PWM settings
6. Buy The Original O4 Pro Camera (Replacement Part)
Flywoo offer spare O4 Pro camera module with the original MP66 gyro here: https://oscarliang.com/product-88nq
The main downsides are:
- you have to replace it yourself
- you may get a “camera calibration error” in your googles live feed and DVR (doesn’t appear in air unit recording)
Final Thoughts
Right now, the situation seems to be this:
- some newer DJI O4 Pro units appear to use a different gyro
- that new gyro may be the same one used in the standard DJI O4
- some pilots are seeing very poor stabilization performance in RockSteady and Gyroflow
- raw footage can still look perfectly fine
- proper soft mounting may help significantly
I really hope DJI acknowledges this and fixes it, ideally in firmware so users don’t need to return/replace their camera which would be a logistic nightmare.
For now, if your O4 Pro footage looks great raw but falls apart when stabilized, and you have already ruled out tune and hardware issues, this new gyro may be the reason.
If you own a DJI O4 Pro, please share:
- whether you are affected
- your production date
- what frame you are using
- whether soft mounting helped
That should help us figure out exactly when the change happened and which batches are affected.
