There’s a brand new concern affecting among the newest DJI O4 Professional Air Items, and it’s one thing FPV pilots ought to learn about. A producer not too long ago reached out to me and identified that the most recent batch of the DJI O4 Professional seems to have modified design internally. Extra particularly, it’s now utilizing a special gyro chip, and that change appears to be inflicting main issues with footage stabilization.
Additional readings:
What’s Taking place?
In easy phrases, DJI have made a number of adjustments to the 2026-production O4 Professional Air Items, together with a special ICM gyro. For some customers, stabilization is not working correctly.
The uncooked, unstabilized footage nonetheless appears nice, however when you attempt to stabilize it utilizing RockSteady or Gyroflow, the picture begins to look horrible: jittering, shaky, unstable, bizarre actions, and typically virtually unusable.
Apparently, this is identical gyro used within the DJI O4 Air Unit, which is thought for being extra delicate to vibration and inflicting complications for pilots attempting to get clear stabilized footage.
Right here’s a detailed up image of the Gyro within the unique DJI O4 Professional: MP66 (MPU-6050 gyro chip)
Listed here are some shut up photographs of the Gyro within the new DJI O4 Professional from 2026: 1469D (ICM-40609-D gyro chip)
And right here’s a detailed up image of the Gyro within the DJI O4 Lite: 1469D (ICM-40609-D gyro chip), you’ll be able to see it’s the identical chip within the new O4 Professional.
At this stage, it’s not clear why DJI switched to a special gyro that has been recognized to be problematic. It could possibly be because of provide chain adjustments, price, availability, or a silent {hardware} revision. However regardless of the cause, it’s clearly inflicting issues for some pilots.
I need to make it clear that I personally haven’t had this concern myself, I’ve used certainly one of these O4 Professional with new gyro within the Firefly25 and it labored completely nice.
However over the previous few weeks, I’ve been listening to the identical grievance many times:
“Why does my O4 Professional footage look completely clear within the goggles, however shaky and horrible in Gyroflow or RockSteady?”
That’s the key symptom.
I’ve spoken to plenty of producers, and so they additionally confirmed that this can be a recognized concern on their facet.
After all, not each shaky video is brought on by the brand new gyro. It is best to nonetheless rule out the standard suspects first:
- dangerous PID/filter tune
- {hardware} issues like bend props, broken motors, or free screws
- poor gentle mounting for digital camera
- an excessive amount of vibration within the body
- ESC settings reminiscent of not utilizing 48kHz PWM
- lack of energy filtering capacitors
However you probably have already checked all of that and your footage continues to be stabilizing badly (whereas your dwell view within the goggles appears nice), then the brand new gyro within the O4 Professional is a probable trigger.
Which DJI O4 Professional Items Are Affected?
Based mostly on what I’ve been advised to this point, in case your DJI O4 Professional was produced or launched after February, there’s a good likelihood it may need the newer gyro chip.
That doesn’t routinely imply it would positively have issues, however the threat appears increased.
How one can Verify If You Are Affected
With out opening the digital camera housing and bodily inspecting the gyro chip, the simpler strategy to examine is by trying on the manufacturing date.
You will discover the serial quantity:
- on the product field, when you nonetheless have it
- on the Air Unit itself, on the backside of the white sticker
How one can Decode the Manufacturing Date
My new unit has a serial code like this: 9F2KP 2B001.
After the 9F2K prefix, there are all the time 3 characters that encode the manufacturing date.
- 1st character = 12 months
- N = 2025
- P = 2026
- O is skipped
- 2nd character = month
- 1–9 = January to September
- A = October
- B = November
- C = December
- third character = day
- 1–9, A, B, C… symbolize consecutive days
- O is skipped
For instance, for 9F2KP2B001, decode the three letters within the center – P2B which might be 2026 February twelfth.
So by decoding these three characters, you’ll be able to work out when your O4 Professional was manufactured.
When you have an affected unit, I’d be very to know your manufacturing date. Even when your unit isn’t affected, please share it. The extra information factors we accumulate, the simpler will probably be to slender down precisely when this {hardware} change began.
Potential Options
I actually hope DJI addresses this quickly, maybe with a firmware replace, change the way in which gyro information is processed possibly. Because the concern appears tied to how the gyro information is being dealt with, there’s at the very least an opportunity this could possibly be improved in software program.
Till then, right here are some things price attempting.
1. Replace All the things
Be sure to are working:
- the most recent O4 Professional firmware
- up to date goggles firmware
- the most recent model of Gyroflow
You need to rule out software program mismatch first.
2. Strive Each RockSteady and Gyroflow
Strive these stabilization individually and see which of them work.
That may assist slender down whether or not the problem is:
3. Enhance Digital camera Delicate Mounting
I occurred to have one DJI O4 Professional with the brand new gyro (produced in 2026 February), and I examined it in each the Flywoo Firefly 20 and Firefly 25.
Curiously, on each of these quads, the stabilized footage and uncooked footage had been completely nice — no jello, no seen vibration, no main stabilization points.
That strongly suggests the issue could be labored round. A correctly designed soft-mounting platform for the digital camera appears to make a giant distinction.
So in case your footage is struggling, one of many first issues I’d take a look at is how the O4 Professional digital camera is mounted in your body.
Take a look at how Flywoo mounts the brand new O4 Professional of their body which appears to work rather well: https://oscarliang.com/flywoo-firefly-25-mini/
4. Strive Low Move Filter in Gyroflow
One other factor you’ll be able to attempt is enabling a low cross filter in Gyroflow, for instance at 5Hz.
This will likely assist clean out problematic gyro information and enhance stabilization outcomes.
It’s not a assured repair, however it’s positively price testing in case you are affected.
5. Verify Your Construct Rigorously
Undergo all the conventional vibration checks:
- props
- motors
- screws
- digital camera mount
- body resonance
- PID tune
- ESC PWM settings
6. Purchase The Authentic O4 Professional Digital camera (Substitute Half)
Flywoo provide spare O4 Professional digital camera module with the unique MP66 gyro right here: https://oscarliang.com/product-88nq
The primary downsides are:
- it’s important to substitute it your self
- you might get a “digital camera calibration error” in your googles dwell feed and DVR (doesn’t seem in air unit recording)
Last Ideas
Proper now, the scenario appears to be this:
- some newer DJI O4 Professional items seem to make use of a special gyro
- that new gyro often is the similar one utilized in the usual DJI O4
- some pilots are seeing very poor stabilization efficiency in RockSteady and Gyroflow
- uncooked footage can nonetheless look completely nice
- correct gentle mounting might assist considerably
I actually hope DJI acknowledges this and fixes it, ideally in firmware so customers don’t have to return/substitute their digital camera which might be a logistic nightmare.
For now, in case your O4 Professional footage appears nice uncooked however falls aside when stabilized, and you’ve got already dominated out tune and {hardware} points, this new gyro often is the cause.
For those who personal a DJI O4 Professional, please share:
- whether or not you might be affected
- your manufacturing date
- what body you might be utilizing
- whether or not gentle mounting helped
That ought to assist us determine precisely when the change occurred and which batches are affected.
