The GEPRC Darkstar22 is a small cinewhoop that makes use of 2.2inch propellers. The additional thrust from barely bigger props makes a noticeable distinction in flight efficiency, particularly when carrying the heavier DJI O4 Professional Air Unit — with out rising the general measurement in comparison with typical 2inch counterparts. On this assessment, I’ll break down my impressions of the Darkstar22’s design, construct high quality, flight efficiency, sturdiness, and the way it compares to the Pavo20 Professional II, and who this drone is greatest suited to.

Design
The GEPRC DarkStar22 is a compact cinewhoop operating 2.2-inch propellers:
- Sufficiently small to fly in tighter areas and shut to things
- Geared up with prop guards, designed for flying close to individuals, vehicles, and property with decreased danger
- The ducts make it surprisingly robust — gentle bumps are far much less catastrophic
- Highly effective sufficient to hold the DJI O4 Professional
- The digicam is soft-mounted to cut back vibration and jello, preferrred for cinematic footage
The cover and ducts are injection-molded plastic. They really feel inflexible, stiff, and robust. On a quad this measurement, the plastic feels beefy — not low cost or brittle. The motors and flight controller are mounted on a 2.5mm thick carbon fiber base plate, which reduces flex and improves flight efficiency.
The XT30 connector is built-in into the rear duct utilizing a neat 3D-printed holder. It’s effectively protected and properly built-in, however your battery lead have to be lengthy sufficient to succeed in it. One draw back is that unplugging batteries may be barely annoying as a result of it stretches your battery wire.
The digicam lens is comparatively effectively protected with none plastic showing the digicam’s view. Nevertheless, I’d nonetheless suggest utilizing an ND or UV filter for extra lens safety, because the digicam mount itself is solely plastic.
An LED strip is built-in contained in the ducts. It’s not RGB — only a single shade (blue). You may flip it on or off utilizing a swap in your radio. It’s already configured in Betaflight and assigned to Channel 8 (AUX 4) within the Modes tab.
That mentioned, it does add additional weight (roughly 10g). Should you’re not a fan of LEDs, you possibly can merely swap to the spare duct as an alternative of ripping out the LED strip from the unique body.
Smooth-Mounted Digicam Cover
Just like the Pavo20 Professional, the Darkstar22 soft-mounts each the digicam and the air unit, it really works very effectively at isolating vibration and minimizing jello within the footage.
Nevertheless, not like the Pavo20 Professional, which secures the cover with bolts, the Darkstar22 depends on 5 rubber grommets to carry the cover in place. In tougher crashes, the cover is more likely to pop off.
It’s additionally fairly fiddly to take away and reinstall. It’s important to push the grommets by way of very tight gaps, and putting in or eradicating them — particularly when becoming the DJI O4 Professional — may be tedious.
Restricted FPV System Choices
Like many BNF producers, the cover and digicam mounting not too long ago seem optimized primarily for the DJI O4 Professional air items greater than anything.
DJI cameras use completely different screw spacing in comparison with conventional analog or Walksnail cameras. Should you plan to mount digicam apart from DJI, you could have to do some DIY modifications.
That’s not essentially a deal-breaker, but it surely’s value figuring out before you purchase a “no FPV system” model anticipating common drop-in compatibility with analog or Walksnail or different methods.
Digicam Angle Limitation
The utmost digicam angle is restricted to roughly 0° to about 30°.
For typical cinewhoop use — indoor flying or relaxed outside cruising — this vary is completely satisfactory. Nevertheless, when you choose greater digicam uptilt for quicker flying, you could want to change the mount your self.

GPS Mounting: Nice Thought, Imperfect Execution
Should you don’t use GPS, this gained’t concern you.
When putting in the mounting plate on the O4 Professional air unit, you could discover a sq. slot within the plate. After securing the air unit, this slot faces upward by way of the cover cutout. It’s designed to carry a GPS module, retaining the construct clear and tidy.
It seems to suit GPS modules with dimensions round 15.5×15.5mm. GPS like HGLRC M100 Mini would match completely.
Nevertheless, as a result of the GPS sits very near the O4 air unit and antennas, there’s potential for interference. This may scale back GPS efficiency — fewer satellites locked and longer time to realize a 3D repair.
In my view, it might have been higher to position the GPS mount on prime of the digicam protector. It could be barely extra uncovered, however GPS modules are typically fairly strong. Extra importantly, mounting the GPS farther away from RF sources would seemingly enhance satellite tv for pc reception and reliability.
Including GPS means that you can allow:
A Small Annoyance: Exterior USB Adapter
On the DarkStar22, it’s important to plug in a small adapter to entry the USB port for Betaflight configuration. It doesn’t make the quad tougher to make use of, but it surely’s precisely the type of tiny half you’ll ultimately lose — particularly when you personal a number of quads with completely different adapters. It shortly turns into messy.
It’s the identical scenario with the Pavo20 Professional. It appears pretty frequent these days for small cinewhoops to interrupt out the USB port to a separate adapter.
The explanations for this design selection are apparent: weight financial savings and simpler entry in compact builds.
And there are two similar connectors on the board, which makes it simple to plug into the fallacious one.
Flight Efficiency
The Darkstar22 hovers at round 21% throttle. It doesn’t really feel notably highly effective. A full throttle punch is noticeably slower than the Pavo20 Professional, seemingly as a result of additional weight.
That mentioned, I don’t have complaints about dealing with. It’s a really clean and steady whoop. Turns really feel clear and predictable.
There’s some propwash oscillation throughout sharp turns and when recovering from dives, however that’s anticipated for a heavier micro cinewhoop.
I additionally seen a tiny little bit of vibrations when flying in windy situations (round 15 MPH within the flight footage). Nevertheless, these may be smoothed out simply in publish utilizing Gyroflow.
For a micro cinewhoop, it truly performs surprisingly effectively in for freestyle and acro. Flips and rolls really feel snappy and responsive.
GEPRC recommends a 3S 720mAh LiHV battery. I didn’t have one obtainable, so I examined it with some BetaFPV 3S 550mAh LiHV packs as an alternative.
With a mixture of freestyle and cruising, I used to be getting round 4–5 minutes of flight time. Should you use a 720mAh pack, you possibly can in all probability anticipate about one additional minute.
Darkstar22 vs. Pavo20 Professional V2
They’re basically the identical measurement — each use 2.2-inch propellers — however there are some necessary variations.
Weight
The Darkstar22 is heavier than the Pavo20 Professional. With the DJI O4 Professional and LED strip put in, it’s roughly 17g heavier.
- Pavo20 Professional II: 116g
- Darkstar22: 133.5g
That seemingly explains why GEPRC recommends a bigger battery — to compensate for decreased flight time as a result of additional weight. Nevertheless, a much bigger battery makes the drone even heavier, which noticeably impacts efficiency.
Takeoff weight together with manufacturer-recommended batteries:
- Darkstar22 (133.5g) + Storm 3S 720mAh (50.5g): 184g
- Pavo20 Professional (116g) + LAVA 3S 550mAh (43.2g): 159.2g
That’s a couple of 25g distinction, which is critical on a small cinewhoop.
Should you’re proud of 4–5 minutes of flight time, I truly assume a 3S 550mAh pack is the higher selection for general flight efficiency.
Pusher vs. Normal Configuration
The Pavo20 Professional makes use of a pusher configuration — motors are mounted the other way up, and the props sit beneath the body.
The Darkstar22 makes use of a regular configuration — props are on prime, like a standard quad.
There are arguments that pusher setups may be barely extra environment friendly, doubtlessly translating to marginally higher flight occasions. Nevertheless, the draw back is that propellers are extra uncovered throughout landings and crashes. This may result in:
- Extra bent or broken props
- Elevated likelihood of micro vibrations (and jello in footage) over time
- Extra frequent upkeep and prop replacements
With the Darkstar22’s normal configuration, propellers are extra protected. When it lands or tumbles, the ducts and arms hit first fairly than the propellers.
I’ve written a extra detailed article discussing these configurations right here: https://oscarliang.com/pusher-configuration-explained/
Which One Flies Higher?
If you’re an skilled freestyle pilot, the Pavo20 Professional is extra enjoyable. Being nearly 20g lighter makes a noticeable distinction in dealing with, responsiveness, and effectivity for drones on this measurement class. That mentioned, you gained’t be upset by how the Darkstar flies. It’s nonetheless clean and nimble, and you’ll completely freestyle with it.
With the identical battery, the Pavo20 Professional offers you nearly a full minute extra flight time, primarily due to its decrease weight.
Vary
The Darkstar has the sting in terms of vary.
It makes use of an exterior ELRS receiver with a better-positioned antenna. On the Pavo20 Professional, the antenna is only a easy copper wire tucked contained in the body, which considerably limits most vary. Flying inside 300m is mostly tremendous, however past that it turns into more and more dangerous.
If vary and sign penetration functionality issues to you, the Darkstar is clearly stronger on this space.
Sturdiness
Each the Darkstar and Pavo20 has strengths and weaknesses.
I’m not an enormous fan of pusher config and attempt to keep away from it when potential. Props on the underside are likely to get broken extra typically, and takeoffs may be tougher if the quad will get caught on particles. The O4 Professional digicam can be barely higher protected on the Darkstar. The battery protector can be a really good contact.
Nevertheless, the soft-mounted cover is the primary weak level. Laborious crashes could cause the cover to separate from the body. Repeatedly eradicating and reinstalling the rubber grommets can even injury them over time.
In distinction, the Pavo20 Professional cover is secured with bolts, making it extra strong and safe. For that purpose, I might keep away from aggressive flying that would result in heavy crashes with the Darkstar.
Upkeep
Upkeep largely comes all the way down to how the cover is mounted.
- Pavo20 Professional: 4 screws to take away. Straightforward to work on and simple to reassemble.
- Darkstar22: To entry the underside of the FC, you take away six screws from beneath. For the highest facet, it’s essential to take away the cover — and reinstalling these rubber grommets correctly may be irritating.
Should you take pleasure in tinkering and don’t crash a lot, it’s manageable. However when you crash typically and need fast repairs, the Pavo is simply simpler.
Noise
Noise issues particularly once you’re flying near individuals, indoors, or round animals.
- Pavo20 Professional: Quieter, with a lower-pitched sound.
- Darkstar22: Barely louder, with a better pitch.
Neither is wherever close to as loud as a 5-inch quad. Just a few hundred meters away, each fade into background noise. But when stealth is a precedence, the Pavo has a slight benefit.
Worth
The Darkstar is roughly $35 greater than the Pavo20 Professional as a full BNF:
- Pavo20 Professional II (O4 Professional + ELRS): $364.99
- Darkstar22 (O4 Professional + ELRS): $399.99
When evaluating PNP variations (with out O4 Professional), the Darkstar is $65 costlier!
You’re paying a noticeable premium for the Darkstar22, so the actual query is: do you get what you pay for?
Putting in the DJI O4 Professional Air Unit
Should you order the model with out the DJI O4 Professional, you’ll want to put in it your self.
I’m barely upset by the shortage of directions on how to do that. For knowledgeable pilots, it’s not an enormous difficulty — you possibly can in all probability determine it out pretty shortly. However for rookies, this might be irritating. On the very least, they need to clarify which screws go the place and the way the air unit needs to be mounted.
The quad features a leaflet within the field, but it surely’s simply generic data for all their BNF drones — not a correct handbook for this particular mannequin. I additionally checked their web site for documentation, however couldn’t discover something. Not essentially the most beginner-friendly expertise.
Anyway, I’ll present how I put in mine right here to make issues clearer.
The right way to Setup
Earlier than the primary flight, I did the next:
- Put in O4 Professional Air Unit
- Put in the battery pad
Firmware
- The flight controller (FC) board goal is TAKERF405, and it comes preloaded with Betaflight firmware model 2025.12.0-beta. For CLI Diff, see right here

Ultimate Verdict
If measurement doesn’t matter and also you simply need the very best flying cinewhoop, I nonetheless choose the GEPRC Cinelog30 V3. It’s extra environment friendly, extra highly effective, extra steady, and surprisingly quiet.
However when you simply need a small 2-inch cinewhoop with the DJI O4 Professional, it actually comes all the way down to the Pavo20 Professional vs. Darkstar22.
Total, the Pavo20 Professional flies higher and longer as a result of lighter weight, and it’s higher suited to close-range freestyle. It’s additionally simpler to keep up and extra reasonably priced.
That mentioned, the Darkstar22 additionally flies effectively and has a strong PID tune, however the heavier weight makes it higher suited to relaxed cruising. Its higher receiver and antenna setup give it noticeably higher vary.
