Design & Construct
I actually preferred the unique Pavo Pico — paired with the DJI O3, it was able to capturing surprisingly lovely footage for its dimension. So I used to be genuinely excited to see BetaFPV improve it to help not solely the DJI O4 Lite, but additionally the O4 Professional Air Unit.
The Pavo Pico II ships with two cover choices, letting you select based mostly on which DJI Air Unit you propose to make use of. Curiously, the cover for the O4 Professional is the very same one used on the Pavo20 Professional, whereas the O4 Lite cover is a brand new design.
At first look, the Pavo Pico II seems fairly just like the Pavo Femto, however there are a number of key variations. The Pico II makes use of bigger 45mm propellers in comparison with the Femto’s 40mm props. Regardless of the scale enhance, the Pico II stays extraordinarily compact — nonetheless a lot smaller than the Pavo20.
Left: Pavo Pico II; Proper: Pavo20
One of many greatest enhancements on the Pavo Pico II is the redesigned digicam mounting system for the DJI O4 Lite, aimed particularly at eliminating jello in footage. On the Pavo Femto, the O4 Lite digicam was held by small rubber strips, which frequently led to undesirable vibration. On the brand new Pico II, BetaFPV fully reworked the design — now the whole digicam cage, together with the Air Unit, is soft-mounted on 4 giant rubber grommets.
The way to Set up the DJI O4 Lite
Mounting the DJI O4 Lite on the Pavo Pico II isn’t probably the most simple course of, particularly since BetaFPV doesn’t present any directions. It took me a little bit of trial and error, however right here’s how I managed to put in it efficiently.
Set up the 4 o-rings on the pillars beneath the cover. These assist cushion the Air Unit’s predominant board.
Place the O4 predominant board into the cover, resting it on the o-rings.
Change the inventory antenna with the shorter antenna included with the Pavo Pico II. The shorter one suits higher and retains the construct compact.
Connect the plastic case to the digicam (this piece comes with the DJI O4 Air Unit however isn’t pre-installed). Be certain it clicks securely in place.
Mount the digicam into the cover utilizing the self-tapping screws offered.
Set up the 4 rubber grommets onto the plastic backside plate of the digicam cage. Observe that the grommet ends are completely different sizes — a smaller aspect and an even bigger aspect. The smaller finish ought to face the digicam cage, whereas the larger finish faces the drone body.
Safe the underside plate to the digicam cage with the 6 tiny screws offered. Tighten them evenly however don’t over-torque them — they’re very small.
Lastly, mount the digicam cage to the drone. There aren’t any screws wanted right here — merely slot the grommets into the carbon fibre body’s cutouts. As soon as in place, the rubber holds the cage securely.
The way to Set up the DJI O4 Professional
Putting in the DJI O4 Professional is far easier — it follows the identical course of because the Pavo20.
Change the inventory antennas with the shorter variations included within the package.
- This step is optionally available, however I extremely advocate it. You’ll save virtually 3 grams, which is substantial on such a light-weight drone.
- The smaller antennas are additionally extra compact, much less prone to snag on branches, and higher fitted to tight areas.
- Except you’re flying lengthy vary, these shorter antennas nonetheless present loads of sign vary — simply a few kilometres open air and greater than sufficient for indoor flying.
Set up the Air Unit inside the cover. It merely clips into place — no screws required.
Safe the digicam into the cover utilizing the screws offered.
Insert the 4 rubber grommets, adopted by the bolts that undergo them.
Join the Air Unit to the flight controller utilizing the present 4-pin cable.
Lastly, mount the digicam cage on high of the drone. Don’t fear about overtightening the bolts — they’re solely threaded midway. Simply hold turning till they cease naturally.
Battery and Charging
Due to the inflexible battery mount design — produced from non-flexible, injection-molded plastic — the Pavo Pico II solely helps batteries of a selected dimension. The slot comfortably suits packs with a width and peak of roughly 25.5 × 24 mm, which limits compatibility considerably.
BetaFPV recommends their LAVA 2S 550 mAh packs, and so they match completely. Different batteries of comparable dimensions may additionally work, however something bigger gained’t slide into the mount simply with out modification.
Get the LAVA 2S 550mAh right here:
You possibly can clip off the battery holder, and loop a strap by means of, so you need to use batteries of different sizes. However that you must get your personal battery strap because it’s not included.
For charging, I’ve been utilizing the Vifly ToothStor, a easy LiPo charger designed for 2S packs. It actually simplifies charging small batteries within the area.
Flight Efficiency & Video High quality
I examined the Pavo Pico II utilizing BetaFPV’s LAVA 2S 550 mAh LiPo packs, flying with each the DJI O4 Lite and DJI O4 Professional Air Items.
PID & Filter Tune
The Pico 2 seems to have a customized PID tune, however the filters are left at default values which I believe might be optimized additional (so can the PID tune). Regardless of the conservative tune, it nonetheless flew fairly properly in my testing, I believe most individuals could be pleased with the way it performs. Anyway I’ll attempt to create my very own filter and PID tune for this quad and publish it on my patreon possibly in per week or two. Let me know within the remark if you wish to see the tune for the O4 Lite or the O4 Professional.
With DJI O4 Lite
Flight time: round 6 minutes
Video high quality: The redesigned soft-mount system fully eliminates jello in my testing. Additionally each DJI Rocksteady and Gyroflow stabilization labored superbly, delivering clean, cinematic footage. Even with none stabilization utilized, the uncooked footage regarded surprisingly clear and vibration-free — completely usable for informal flying.
Dealing with: With the lighter O4 Lite put in, the Pavo Pico II feels extraordinarily nimble and agile, supreme for tight areas or fast-moving pictures. It’s fast, responsive, and playful — excellent for park flying, indoor flights, or gentle freestyle.
With DJI O4 Professional
Flight time: round 4.5 minutes
Video high quality: As anticipated from the DJI O4 Professional, picture high quality is excellent. You get crisp 4K footage with wealthy element and wonderful shade depth, even in breezy circumstances. I strongly advocate including an ND filter, each to enhance picture high quality and shield the lens. The O4 Professional digicam sits barely ahead of the prop guards, making it susceptible in crashes. BetaFPV sells a devoted ND filter set for the O4 Professional: https://oscarliang.com/betafpv-nd-filters-dji-o4-pro/.
Dealing with: Regardless of the added weight, the Pico II nonetheless performs fairly properly. The LAVA 1102 motors deal with the load with ease, giving the drone sufficient thrust for clean cinematic cruising. It’s noticeably slower and “tankier” than with the O4 Lite, and barely much less responsive. I believe it’s supreme for gradual, flowing, cinematic pictures reasonably than quick, acrobatic maneuvers.
The way to Setup for the First Flight
Connecting the Pavo Pico 2 to Betaflight Configurator utilizing the offered USB-C adapter (the port is positioned on the rear of the drone).

Open browser and go to 10.0.0.1, then enter your bind phrase on the webpage. Detailed directions might be discovered right here: https://oscarliang.com/bind-expresslrs-receivers/#Methodology-3-Getting into-Bind-Phrase-in-Internet-UI
- Pair the DJI O4 Air Unit together with your Goggles: Observe the directions right here: https://oscarliang.com/how-to-setup-dji-o4-lite/#Pairing-DJI-Goggles-3-with-O4-Lite. The O4 doesn’t require activation, so you may fly as quickly because it’s paired.
- Setup the Modes Tab: Configure your arm swap, angle mode, and turtle mode. For steerage, see this tutorial: https://oscarliang.com/betaflight-modes/#How-to-Setup-Arm-Change
- In Energy tab, set warning voltage to three.4V, and min voltage to three.2V – I are inclined to land when voltage drops to three.3V resulting from voltage sag, and once you land the voltage would usually rise to three.5-3.6V.
That’s it—your Pavo Pico 2 ought to now be prepared for its maiden flight!
Closing Ideas – Who Is the Pavo Pico II For?
The BetaFPV Pavo Pico II fills a novel spot within the Pavo lineup. Whereas the Pavo Femto solely helps the DJI O4 Lite, and the Pavo20 solely helps the DJI O4 Professional, the Pico II is probably the most versatile of the three — it helps each air models proper out of the field!

With the lighter DJI O4 Lite, the Pico 2 really shines. It transforms right into a nimble micro ripper — quick, enjoyable, and able to weaving by means of tight areas with ease. The bigger 45mm props give it noticeably extra thrust and effectivity than the Femto, whereas the improved digicam mount principally eliminates jello. Regardless of being virtually the identical weight, it performs much better open air, making it my most popular selection between the 2.
