Whereas I’ve a few years of expertise flying drones, I’ve barely dabbled my toes within the waters of extra superior and technical first-person view (FPV) autos. That is the angle with which I reviewed the DJI O3 Air Unit, which is a digicam and picture transmission system designed for hobbyists who do not thoughts getting their arms soiled with screwdrivers and soldering instruments.
Testing the O3 Air Unit was fairly an eye-opening expertise into the difficult, but extremely rewarding world of constructing and working FPV drones and different RC units. It required plenty of trial, error, and normal troubleshooting — all searching for the reply as as to if or not the O3 Air unit is one thing reserved for the devoted hobbyist, or if extra informal drone and RC fans may do properly to think about profiting from the thrilling potentialities it represents.

The O3 Air unit is a quite simple, bare-bones system. It incorporates a digicam, an antenna, and a transmission unit — and these three parts are linked through cables. The core unit of the gadget incorporates a connector designed to be plugged right into a appropriate flight controller, in addition to USB-C and microSD card ports, plus a pairing button.
The development of the DJI O3 Air Unit is extraordinarily sturdy and high-quality, though it is not waterproof. The compact, high-performance nature of the gadget is such that it wants each little bit of airflow it could possibly get for cooling.

Palms On with the DJI O3 Air Unit
Getting the O3 Air Unit up and working was a journey, although none of my difficulties have been the fault of the gadget itself. Moderately, my trials and tribulations have been the results of early firmware and my very own inexperience with wiring and with hobbyist remote-controlled (RC) drones.
First off, I wanted to energy the gadget. This could be completed most simply by merely plugging the O3 Air Unit right into a appropriate flight controller. Nevertheless, I lack such a flight controller, and my main curiosity within the O3 Air Unit is as a tool with which to expertise ground-based RC autos. With this in thoughts, and after plenty of analysis, I finally ordered a 500mAh LiPo battery, a charger, and an adapter to go between the battery and the charger. I additionally bought a pigtail connector to attach the battery on to the O3 Air Unit.
Hooking up the battery connectors was the one tough and technical facet of this mission, because it concerned snipping the facility and floor wires on the O3 Air Unit and soldering them to the pigtail connectors.
With this whole, I used to be capable of efficiently energy on the O3 Air unit for the primary time. I wish to give a giant shout-out right here to GetFPV.com for his or her wonderful customer support, which helped me work out what elements I wanted to order.

In the event you plan to comply with an analogous route as I did with the O3 air unit, I like to recommend shopping for a high-quality battery charger since you do not wish to fiddle with LiPo batteries. Additionally, if you happen to’re constructing a low-speed car or if you happen to plan to mount it in a location the place the air unit will not be uncovered to a major quantity of air circulation, you also needs to plan to incorporate some form of cooling fan .
After I used to be capable of energy the O3 Air Unit, I nonetheless needed to get it paired to my DJI Goggles 2 and controller. I actually struggled with this, however after a short forwards and backwards with DJI, we narrowed the issue right down to prelaunch firmware, and after a fast replace for the controller, headset, and air unit, I had every part up and working. I shortly strapped the O3 Air Unit to an RC race automotive with packaging tape and took it for a spin across the storage.

With this profitable check run, I upgraded my setup to an RC monster truck, utilizing double-sided mounting tape and electrical tape to safe the cab of the truck. The O3 Air Unit labored nice on this setup, although sadly, the monster truck was not as off-road succesful as marketed.

Subsequent, I put the O3 Air Unit to its extra conventional use as a drone digicam, taped to the highest of my DJI FPV drone. I apprehensive that the tape may not be sturdy sufficient, however thankfully, it turned out to be rock strong. Each the drone and air unit carried out admirably, although sooner or later, I plan to mount the Air Unit at a greater angle on the DJI FPV drone in order that the propellers are excluded from the view.
DJI O3 Air Unit picture high quality
DJI O3 Air Unit vs DJI FPV Drone vs DJI Avata vs DJI Mavic Three Traditional – video high quality comparability
With the aptitude of recording 4K video at 60 frames per second (fps) and a couple of.7K video at 120 fps, the O3 air unit is sort of highly effective as a videography software. With RockSteady picture stabilization just like what you’d discover within the DJI Motion 3, the O3 Air Unit may function an sufficient alternative for the motion cameras usually utilized by FPV drone pilots. That is probably enormous, because it means critical weight financial savings and, thus, a efficiency enhance in conditions the place each gram issues.
It is a main enchancment over the unique DJI Air Unit by way of picture high quality and a giant enchancment over the digicam built-in into the DJI FPV drone. It is roughly on par with the DJI Avata digicam, although in my subsequent setup utilizing this digicam, I intend so as to add a bit of froth or rubber between the O3 Air Unit digicam module and the RC car to assist dampen the vibrations and obtain smoother footage.
DJI O3 Air Unit efficiency

I by no means had any trigger to complain concerning the transmission high quality or power of the O3 Air Unit. Utilizing the DJI Goggles 2 with it, I by no means skilled any noticeable lag or lack of sign, although it must be famous that I by no means actually pushed the bounds of its vary. I used it as I’d FPV drones in the true world, the place I’m at all times cautious to remain inside visible line of sight. I did, nevertheless, drive it with RC automobiles with a strong wall between myself and the automotive and did not expertise any loss or degradation within the sign.
A very spectacular facet of the O3 Air Unit is its 20GB of onboard storage.
The one important downside I bumped into was overheating, as I’ve already alluded to. To be clear, this can be a system designed for use with drones touring at a excessive price of pace by the air. Nevertheless, the speed at which it overheats is considerably alarming when it isn’t actively being cooled. It made the O3 Air Unit slightly tough to replace, and I ended up working my NiteCore BlowerBaby air-cleaning gadget over the O3 Air Unit through the troubleshooting and setup course of. When flying it on a drone, this is not a difficulty, and there may be an automated shutoff that happens if the gadget will get too sizzling.
A very spectacular facet of the O3 Air Unit is its 20GB of onboard storage. This can be essentially the most onboard storage I’ve personally encountered on a digicam of any description, and it may be an actual lifesaver to have this selection as a backup to a microSD card.
DJI O3 Air Unit worth and availability
Andy Zahn / Digital Developments
The DJI O3 Air Unit is offered now and retails for $230, which incorporates the digicam module, transmission module, antennae, and 3-in-1 cable. That is really fairly a beautiful worth level, contemplating its capabilities, although it is essential to notice that additionally, you will want a headset such because the DJI Goggles 2, which retail for $650.
In the event you’re ranging from scratch, you additionally want to think about the price of no matter you are going to connect the O3 Air Unit to. The battery, adapters, and charger I bought price me $102 whole, and that represents the naked minimal to get the O3 Air Unit up and working. I spent a further $30 on an affordable RC monster truck, however after being dissatisfied by the lackluster efficiency of this cut price bin truck, I’d suggest spending not less than twice that to get one thing with good energy and shock absorbers.
In the event you go for a drone as an alternative, as is extra the intent of the DJI O3 Air Unit, count on to spend a number of hundred {dollars} not less than on the drone itself. All informed, a whole FPV setup constructed across the O3 Air Unit will run round $1,00zero at a minimal. That places you within the ballpark of the DJI Avata, which I would suggest to rookies simply seeking to get into FPV drone flight.
A flexible system for FPV hobbyists
Andy Zahn / Digital Developments
The DJI O3 Air Unit is a transparent winner relating to picture transmission for FPV management of drones, automobiles, and RC autos of assorted descriptions. Whereas it’s actually geared toward these of a hobbyist mindset with a sure diploma of technical data, the training curve is not so nice as to severely restrict its accessibility.
It is virtually a foregone conclusion that the O3 Air Unit will develop into the de facto digicam of alternative for hardcore FPV drone pilots. It is a digicam that tickles the creativeness and lends itself to artistic initiatives. It is dependable, highly effective, and delivers wonderful picture high quality that is ok to interchange a standalone motion digicam.
