In case you are at present out there for a brand new micro FPV drone that includes the DJI O4 Lite Air Unit, this publish is for you! Whether or not it’s a tiny whoop or open-prop 1.6-inch or 2-inch ultralight toothpick quad, I believed this could be a superb alternative to share my ideas on the favored fashions available on the market, and assist others resolve which quad may finest swimsuit their flying fashion.
Why DJI O4 Lite?
The DJI O4 Air Unit (Lite) is good for micro FPV drones if professional-grade footage isn’t your precedence and also you’re flying primarily for enjoyable. As talked about in my DJI O4 Professional overview, the Professional model is best in practically each facet however is considerably heavier, bigger, and nearly double the value. The O4 Lite is lighter, extra compact, and simpler in your pockets for those who anticipate frequent crashes and repairs.
Flywoo Firefly18
Specs:
Battery: 1S Prop Dimension: 45mm bi-blade Motor: 1002 19800KV Weight (with out battery): 39g Value: $239.99
The place to Purchase:
The Flywoo Firefly18 might be my favourite 1S “open prop” micro drone I examined in 2025. It’s loads of enjoyable to fly within the park — nimble, quiet, and straightforward to manage. The spotlight of this drone is the wide-angle lens (additionally made by Flywoo). It actually transforms the DJI O4 expertise, delivering extra immersive footage and making this drone an excellent higher worth for content material creators and cinematic flyers. It’s not the lightest or most aggressive performer in its class, but when your precedence is stabilized 4K video from a 1S quad that also flies nicely, it’s arduous to beat this setup.

WalleFPV Eagle2
Specs:
Battery: 3S Prop Dimension: 1.6inch 3-blade Motor: 1002 Weight (with out battery): 72g Value: $224 (PNP)
The place to Purchase:
In order for you the smallest drone designed for the DJI O4 Professional Air Unit, that is the one I’d suggest. The WalleFPV Eagle2 is a powerful little drone that delivers big-drone efficiency in an extremely compact type issue. It makes use of 1.6-inch propellers, and with the battery the takeoff weight is barely 106g!
For a palm-sized FPV drone, it’s surprisingly agile and enjoyable to fly — good for cruising round native parks or your yard. The Eagle2 is a really gratifying and extremely really helpful selection.

BetaFPV Pavo Pico 2
Specs:
Battery: 2S Prop Dimension: 45mm 3-blade Motor: 1102 14000KV Weight (with out battery): 54g (with O4) Value: $104.99 (PNP)
The place to Purchase:
I actually take pleasure in flying the Pavo Pico 2, it actually shines with the lighter DJI O4 Lite – it’s quick, enjoyable, and able to weaving via tight areas with ease, only a nice micro ripper. In comparison with the Femto, I want this Pico 2. The bigger 45mm props give it noticeably extra thrust and effectivity, whereas the improved digicam mount additionally eliminates jello. Regardless of being nearly the identical weight, the Pico 2 performs higher in nearly each elements.
Extra impressively, it additionally helps the DJI O4 Professional air unit which makes it extremely versatile! Try my full overview:
Sub250 Nanofly20
Specs:
Battery: 2S Prop Dimension: 2inch tri-blade Motor: 1002 14000KV (not the advertized 21000KV) Weight (with out battery): 42g Value: $279.99
The place to Purchase:
The Sub250 Nanofly20 is an open-prop drone designed for open areas. Open-prop drones are typically quieter, extra environment friendly, quicker, and considerably extra responsive than whoop drones with propeller guards. With a typical 2S 550mAh battery, anticipate roughly 5 minutes of flight time. One factor to bear in mind is the motor KV score, which feels excessive for 2-inch tri-blade props. This will result in hotter motors if pushed aggressively. Be cautious when adjusting the grasp slider in your PID tuning settings to keep away from overheating or injury.
A major disadvantage of the Nanofly20 is its video. Sub250 mounts the DJI O4 Lite digicam instantly inside a TPU cover with none tender mounting. Because the DJI O4 digicam is delicate to vibrations, you’ll discover appreciable jello and shakiness within the goggles. Though it information in 4K, the gyro knowledge is simply too noisy for dependable stabilization, making cinematic footage tough. Moreover, the quad displays wobbling throughout aggressive maneuvers, doubtlessly because of a PID tuning problem or motor overload from these heavy tri-blade props.
One other level of consideration is the value tag. At $279, the Nanofly20 feels barely overpriced given its comparatively easy construct and video high quality issues.
Total, the Nanofly20 is constructed for enjoyable and freestyle flying somewhat than cinematic work. Whereas it excels in agility and pace for park flying, the noticeable vibration, jello, and excessive price ticket make it a difficult advice.
Sub250 Nimble65
Specs:
Battery: 1S Prop Dimension: 65mm Tri-blade Motor: 0702 27000KV Weight (with out battery): 27g Value: $229.99
The place to Purchase:
I can not suggest this mannequin.
The motor and prop mixture is severely underpowered for a digital construct that weighs 27 grams. Anticipate sluggish efficiency, poor responsiveness, and an total unenjoyable flight expertise.
The true deal-breaker is how Sub250 determined to energy the DJI O4 Lite instantly from the battery—a significant problem for 1S O4 builds. As I’ve repeatedly emphasised in my weblog posts, the DJI O4 Lite struggles when enter voltage drops under 3.7V, leading to unstable video and even full lack of sign. A correct 5V BEC ought to have been used to make sure constant energy for the O4 all through the flight. Sub250 clearly rushed their DJI O4 releases this time, and the Nimble65 is proof of that.
Flywoo Flybee 16/Flylens 75
Specs:
Battery: 2S Prop Dimension: 40mm (1.6inch) 3-blade Motor: 1003 14800KV Weight (with out battery): 45.7g Value: $249.99
The place to Purchase:
The Flywoo Flybee16 is basically the Flylens75 cinewhoop with out prop guards—I suppose that’s Flywoo’s simple strategy to making a brand new mannequin and not using a full redesign. As anticipated, eradicating the prop guard reduces weight by over 10 grams, enhancing flight efficiency, effectivity, pace, and noise ranges.
Nonetheless, the pusher design is probably not best for a freestyle drone that you simply fixed crash and must take off anyplace within the subject. The props are so uncovered and near the bottom it complicates takeoffs and landings, significantly when utilizing turtle mode, as props can simply get caught by grass or particles. Moreover, inserting the O4 Air Unit on the underside, even with protecting plastic, raises sturdiness issues since you are repeatedly touchdown/crashing on it.
On a optimistic word, Flywoo’s methodology of mounting the DJI O4 digicam seems among the many cleanest, most dependable for Rocksteady or Gyroflow stabilization. Different methods of mounting the O4 digicam, just like the one within the BetaFPV Meteor75 Professional, tends to supply barely extra inconsistent outcomes (though it did work nicely for me a lot of the instances).
The Flybee16 appears to be a fairly nimble drone for outdoor, it’s not probably the most highly effective drones on the market, and is extra suited to cruising or gentle freestyle flying. And it displays noticeable prop wash throughout aggressive maneuvers.
On condition that it’s an open-prop micro quad, indoor flight or flying close to individuals isn’t really helpful. And on this case, would I take into account the Flylens75 with O4 Lite? Most likely not, as a result of the O4 digicam is simply not adequate for any cinematic flying. I might somewhat get the model with bare O3 to be trustworthy, which gives superior video at comparable weight.
Flywoo Flybee 20 / Flylens 85
Specs:
Battery: 2S Prop Dimension: 2inch 2-blade Motor: 1003 14800KV Weight (with out battery): 47.6g Value: $249.99
The place to Purchase:
The Flybee20 mirrors the Flybee16 however incorporates a bigger 85mm body and 2-inch bi-blade props. The remainder of the {hardware} are equivalent, together with motors. And it’s primarily a ductless Flylens85, over 20g lighter, providing method higher flight time and efficiency.
I beforehand reviewed each the Flylens75 and Flylens85, and I most well-liked the Flylens85. The bigger Flylens85 merely flew higher for me and offered barely longer flight instances, probably because of its extra environment friendly two-blade propellers. Because the Flybee16 and Flybee20 are primarily ductless variations of the Flylens collection, I anticipate comparable efficiency variations between the Flybee fashions as nicely. Contemplating their comparable weights, I’d go for the mannequin with bigger props any day.
Between the Flybee16 and Flybee20, the Flybee20 is the higher total drone. Likewise, between the Flylens75 and Flylens85, the Flylens85 can be the superior choice.
Flywoo Flytimes 85
Specs:
Battery: 2S Prop Dimension: 2inch 2-blade Motor: 1003 14800KV Weight (with out battery): 58.9g Value: $269.99
The place to Purchase:
The Flytimes85 is basically a hybrid of the Flylens85 and Flybee20, that includes lighter prop guards for diminished weight and a few degree of propeller safety. Its weight falls between these two fashions, whereas different specs stay equivalent.
Except you particularly require propeller safety, I’d suggest the Flybee20 for outside freestyle flying. The Flytimes85 may swimsuit combined flying environments the place you continuously transition between indoor and outside areas. Nonetheless, realistically, a 2S 2-inch whoop is barely too massive and highly effective for flying in the home for my part. Moreover, the DJI O4’s video high quality isn’t enough for cinematic functions. If cinematic footage is your objective, take into account upgrading to the DJI O4 Professional.
GEPRC T-Cube18
Specs:
Value: $269.99 Battery: 2S Prop Dimension: 45mm 3-blade Motor: 1002 18000KV Weight (with out battery): 50g
The place to Purchase:
This can be a new providing, and there isn’t a lot info out there on-line but in addition to the specs. Let’s take a better take a look at that.
The very first thing that stands out to me is how heavy the T-Cube18 is for an open-prop micro quad. It’s 2.5g heavier than the Flybee20 which even has greater motors and propellers. Whereas the motors are smaller, they compensate with a really excessive KV score of 18000KV, nevertheless that could be a little excessive and raises issues about effectivity and potential motor overheating.
The body design is tanky and seems crash-resistant. It additionally retains the props out of the digicam view, stopping them from showing in your footage. Nonetheless, I nonetheless assume the burden is a bit extreme for my liking given these tiny props. Moreover, its worth of $269.99 feels barely excessive IMO.
BetaFPV Meteor75 Professional
Specs:
Battery: 1S Prop Dimension: 45mm tri-blade Motor: 1102 22000KV Weight (with out battery): 37.2g Value: $199.99
The place to Purchase:
I actually loved flying this whoop indoors—it’s most likely my favourite 1S whoop outfitted with the DJI O4 in the mean time. I gained’t go into an excessive amount of element right here since I’ve written a complete overview you may take a look at:
BetaFPV Pavo Femto
Specs:
Battery: 2S Prop Dimension: 40mm 3-blade Motor: 1102 14000KV Weight (with out battery): 54.8g Value: $224.99
The place to Purchase:
The Femto, powered by a 2S battery, is extra highly effective than the1S Meteor75 Professional and might deal with stronger winds outdoor. Nonetheless, this elevated energy comes with trade-offs: the Femto is noisier and fewer agile indoors because of its heavier weight. The smaller props imply that the motors must work tougher (spinning at increased RPM) to maintain the drone afloat in comparison with the Meteor75 Professional, making it louder and considerably much less environment friendly. On the flip facet, the quicker RPM response interprets to higher uncooked efficiency and responsiveness.
Whereas the Femto’s enhanced energy is interesting for outside flying in calm situations, it’s in an ungainly place. For indoor flying, I nonetheless assume the Meteor75 Professional gives superior dealing with. Outdoor, the Femto flies nicely, solely when the climate is calm; as quickly because the wind picks up, I begin to discover some wobble and jello within the footage, and the drone may be pushed round extra simply than bigger fashions. Try my overview to study extra:
The newer Pavo Pico 2 is simply an total higher drone than the Femto – extra highly effective, environment friendly with out jello. That’s why there is no such thing as a level getting the Femto to be completely trustworthy.
HappyModel Mobula7 O4
Specs:
Battery: 2S Prop Dimension: 45mm 3-blade Motor: 1102 10000KV Weight (with out battery): 38.2g Value: $272.99
The place to Purchase:
The Mobula7 O4 presents an attention-grabbing setup. It’s primarily in the identical class because the 1S BetaFPV Meteor75 Professional regardless of being 2S. That’s as a result of its motor KV is lower than half that of the Meteor75, and so they have the identical prop dimension, the motor RPM could be comparable since RPM=KV*voltage. Their weights (with out batteries) are additionally fairly shut.
Nonetheless, do not forget that 2S batteries have two cells, making the battery weight a minimum of double—and sure even heavier because of the XT30 connector in comparison with BT2.0. This elevated battery weight considerably raises the takeoff weight, affecting total flight efficiency.
When it comes to precise flight efficiency, the Mobula7 O4 seems to fly nicely, each agile and steady. But, regardless of its gentle body, it lacks enough energy for severe outside freestyle, which is anticipated from a tiny whoop of this dimension. You’ll be able to fly it outdoor, however solely in calm situations, and also you shouldn’t anticipate distinctive freestyle capabilities.
For me the first disadvantage is video high quality, which reveals noticeable jello and vibration—even earlier than any stabilization is utilized. This probably stems from the digicam being mounted instantly inside the cover with out vibration isolation. One other draw back is that the digicam angle doesn’t look like adjustable.
Conclusion – Which is the Greatest DJI O4 Micro Drone?
2S or 1S for DJI O4?
A 2S setup is absolutely the candy spot for the DJI O4 Air Unit as a result of it may be powered instantly from the battery, simplifying the construct considerably. In distinction, a 1S setup requires powering the O4 by way of a BEC or devoted voltage regulator to make sure reliability. At the moment, most 1S AIO flight controllers lack a sufficiently highly effective 5V BEC, that means producers should develop new flight controllers particularly outfitted with sturdy BECs. As of now, BetaFPV is among the many few producers offering this feature (particularly the 3in1 Matrix FC board).
For Indoor Flying
For indoor flying, my best choice is the Meteor75 Professional. Personally, a light-weight 1S setup is good indoors—2S drones really feel too heavy and too highly effective for snug flying in the home. The 1S batteries are additionally cheaper, simpler to cost, and the setup produces much less noise total. Some pilots dislike the digicam tender mounting on the Meteor75 Professional, believing it introduces jello in footage. Nonetheless, in my expertise, it labored completely wonderful, so the precise explanation for their problem stays unclear.

One other good choice is the Mobula7 O4, nevertheless it’s a 2S drone, and also you’ll want to contemplate in case your house comfortably accommodates its further energy and weight. Though extra highly effective than the Meteor75 Professional, if you end up flying at solely 30-40% throttle, the lighter and cheaper Meteor75 Professional makes extra sense, particularly given the Mobula7 prices $73 extra.

For Outside Flying
For outside use my advice could be the Flywoo Firefly18 – it’s quiet and stealthy. In order for you a bit extra wind resistance and extra energy, take into account the Flybee20. Whereas I’m not a giant fan of its inverted design, it delivers clear and jello free video. Flight efficiency additionally appears to be strong; it’s not absolutely the strongest 2-inch quad out there, nevertheless it’s greater than succesful for informal freestyle flying in your native small parks.

For each Indoor and Outside?
For those who’re in search of one thing versatile sufficient for each indoor and outside flying, it must be a whoop in fact. Many choices just like the Happymodel Mobula7, BetaFPV Femto, and Flylens85 are all succesful—however they don’t excel at both class. I extremely suggest selecting a drone that excels in a single atmosphere somewhat than settling for mediocrity in each. As an illustration, whereas the Meteor75 Professional may also deal with outside flying beneath calm situations, it’s slower than 2S quads and higher suited as an indoor whoop.
