Which DJI O4 5-Inch BNF FPV Drones Ought to I Purchase? A Detailed Comparability

I’m planning to purchase a brand new 5-inch BNF FPV drone with the DJI O4 Professional Air Unit for freestyle, cinematic and presumably some lengthy vary flying, so I assumed this might be an excellent alternative to doc my thought course of and clarify how I resolve which mannequin to get.

The DJI O4 Professional was solely launched final month, however there are already a couple of strong choices that assist it. Nevertheless, with so many components to contemplate—efficiency, sturdiness, ease of restore, and worth for cash—selecting the correct one isn’t all the time easy.

On this submit, I’ll evaluate the high BNF drones that come able to fly with the DJI O4 Air Unit, analyzing their specs, design, usability, and long-term reliability primarily based on my expertise.

Let’s break it down.

The Contenders: 5-Inch BNF Drones with DJI O4 Professional Air Unit

Listed below are a few of the most notable Bind-and-Fly (BNF) 5-inch FPV drones at present available on the market that assist the DJI O4 Air Unit:

Every of those drones comes pre-built with DJI O4, making them nice decisions for pilots who don’t wish to construct their FPV drone from scratch. However how do they evaluate in weight, sturdiness, repairability, and total efficiency?

Let’s dive into the main points.

O4 Professional or O4 Lite?

Personally, I want the O4 Professional on a 5-inch drone. As talked about in my DJI O4 Professional assessment, the Professional model is higher in nearly each manner aside from weight and value. So until you’re flying a micro drone, the O4 Professional is the higher alternative for a 5-inch construct, for my part.

Sadly the Axisflying Manta 5 SE solely comes with the O4 Lite, which is a dealbreaker for me. It additionally makes use of the Axisflying aluminum case, which I mentioned in my earlier submit—I don’t suppose it justifies the excessive value. I beforehand reviewed the Manta 5SE and actually just like the body design, and I want it got here with the O4 Professional as a substitute. Hopefully, Axisflying will launch one other model sooner or later with the full O4 Professional system.

Weight – How Heavy Are They?

Weight performs an enormous function in flight efficiency, effectivity, and sturdiness. A lighter quad is extra agile and environment friendly, whereas a heavier quad tends to endure from shorter flight occasions and fly like a tank—nice for stability, however not splendid for freestyle agility.

Right here’s a breakdown of the takeoff weight (excluding battery and GoPro) for every mannequin:

Are Facet Plates Lifeless Weight?

One factor I actually dislike about a few of these BNF quads is the cumbersome plastic facet plates. Whereas they might look good and supply some safety, in lots of circumstances, they’re simply lifeless weight that:

• Compromises airflow to the electronics, doubtlessly lowering cooling.
• Makes it tougher to take aside the quad for upkeep and repairs.
• Provides pointless weight, lowering effectivity and agility.

Simply check out the burden distinction between the Axisflying Manta 5 SE and the remaining. By not utilizing facet plates, you may doubtlessly save as much as 30g, as I additionally demonstrated in my submit “The right way to make your FPV drone lighter“.

Fortunately, a few of these quads—just like the Seeker5, Vapor D5, and CineFlow—mean you can take away the facet plates when you want a lighter, extra accessible construct. Nevertheless, the iFlight Nazgul would possibly show tougher since the facet plates look like an integral a part of the body design.

That is the Seeker5:

That is the Vapor D5:

That is the Cineflow:

If weight and ease of restore are priorities for you, contemplate going for a mannequin with detachable facet plates or a minimalist body design.

Body Design

For freestyle flying (or simply flying on the whole), the iFlight Afterburner Sport stands out because the least sensible body in terms of upkeep. Simply wanting on the sheer variety of screws and elements, I can already inform it’s going to be a ache to restore or change parts.

On its product web page, iFlight claims that the Afterburner Sport is “designed to push the boundaries of pace, agility, and sturdiness.” However right here’s what confuses me:

• It makes use of the 2207 motors identical to the Nazgul and lots of different BNF drones.
• But, it’s 30g to 50g heavier than comparable fashions.
• If weight is immediately tied to agility and pace, how does a heavier drone “push boundaries”?
• You’ll, for positive, get props in digicam’s view. To get any helpful cinematic footage you’ll have to use a GoPro on high which makes it even heavier.

If you’d like one thing that seems to be distinctive, perhaps the Afterburner Sport will enchantment to you. However for me, it simply doesn’t make sense, and I’ll doubtless exclude it from my choices.

Props in view?

Personally, I’d go for a deadcat body design as a result of the DJI O4 Professional has an especially large area of view (FOV). A deadcat-style body is significantly better at maintaining props out of the digicam’s view in comparison with a True-X body.

Digital camera Safety

A superb DJI O4 setup wants correct digicam safety and gentle mounting to get clear footage.

• Gentle-mounted digicam? – Helps scale back jello and vibrations.
• Digital camera safety? – Does the digicam stick out an excessive amount of? Is the body designed to guard the digicam in crashes?

All the iFlight BNF quads appear to have the O4 digicam protruding loads, making it extra weak in crashes.

That is the Nazgul ECO:

That is the Nazgul Evoque:

The GEPRC Vapor D5 supplies respectable digicam safety, which is a plus. As for the DeepSpace SEEKER5 DC, I couldn’t discover photos of it with an O4 digicam, however its O3 model, it appears to supply respectable safety as properly.

Ease of Restore

Drones crash and break—that’s simply the fact of FPV. A well-designed body ought to be straightforward to take aside for repairs and upgrades.

The DeepSpace SEEKER5 DC has a distinctive cut up top-deck design the place the digicam cage has its personal high plate. Because of this to entry the FC stack and VTX, you solely have to take away six screws of the secondary high plate—an excellent design alternative for straightforward upkeep.

For the remainder of the quads, you’ll sometimes have to take away all the high plate to entry the electronics:

• GEPRC Vapor D5 – 10 screws
• iFlight lineup – 8 screws

To be trustworthy, this isn’t a dealbreaker because you gained’t have to take the quad aside that steadily. But when straightforward upkeep is a high precedence, the Seeker5 DC is value contemplating.

Right here’s the Vapor D5:

Right here’s the Nazgul Evoque:

Right here’s the Cineflow:

Sturdiness

Sturdiness is essential, particularly for freestyle and bando flying. Thicker carbon fibre and a robust body design assist quads survive crashes higher. Thicker arms additionally enhance stiffness and scale back vibration which is essential to ease of tuning. Some quads use 6mm thick arms for sturdiness, whereas others go along with 5mm to avoid wasting weight.

I’ve personally flown the Nazgul ECO (analog model) loads, which has 5mm arms. In my expertise, they provide loads of stiffness and minimal vibrations. Would 6mm arms be extra sturdy? Most likely. However the tradeoff is additional weight. For most individuals, 5mm arms ought to be wonderful until you’re continually flying in high-risk environments (bando diving, hardcore freestyle, and many others.).

Flight Controller and ESC

By way of FC and gyro, there’s nothing out of the atypical—all these choices ought to work simply wonderful. New to FCs? Be taught concerning the completely different processors and gyros right here: https://oscarliang.com/flight-controller/

In the case of ESCs, all of the choices within the desk ought to work properly, however there’s one vital factor to notice:

Current BLHeli_32 ESC will proceed to work as they’re, so it’s probably not a dealbreaker, however preserve it in thoughts when you care about futureproofing.

The BEC is principally a voltage regulator on the FC that can be utilized to energy the DJI O4 Air Unit. Whereas the O4 Professional can take direct 6S LiPo voltage, utilizing a BEC remains to be beneficial as a result of it acts as an influence filter, defending the air unit from potential voltage spikes and damages.

At 1200mW output energy, the O4 Professional consumes round 10W to 11W, so a BEC with a minimum of 9V 2A output is required for secure operation.

Word: The iFlight Evoque F5 V2 and SH CineFlow 5 use the BLITZ Mini F7 FC, which doesn’t have a built-in BEC for the DJI O4 Air Unit—you’ll have to energy it immediately from the battery (VBAT), which suggests you lose filtering and voltage safety.

Moreover, all these flight controllers embrace onboard Blackbox reminiscence, which is crucial for superior PID tuning and filter changes. The Evoque and CineFlow has 8MB of reminiscence (BLITZ Mini F7), the Nazgul ECO has 32MB (iFlight BLITZ ATF435), whereas the remaining have 16MB.

Motor Measurement and KV

All these fashions use 2207 motors. The upper KV might be extra highly effective at the price of being extra energy hungry. I feel it’s changing into a development within the pastime to make use of larger KV motors, whilst you don’t must fly full throttle on a regular basis, having additional energy once you want it’s an enormous benefit. For cruising at reasonable speeds, small KV variations gained’t considerably impression flight time—the motor design and total drone weight have an even bigger impact on effectivity. Personally, I want barely larger KV motors for his or her versatility.

GPS

The subsequent consideration is whether or not the drone comes with GPS. I extremely suggest getting a BNF with GPS, as it will possibly save your drone someday when you lose sign—it’d simply fly again to you utilizing Betaflight Rescue Mode.

Additionally, take note of the place the GPS is mounted. The optimum location ensures fast and constant satellite tv for pc lock earlier than and through flight. If it’s mounted too near the VTX antenna (or worse, beneath it), GPS efficiency could endure as a result of interference.

Personally, I like how the Seeker5 DC mounts its GPS—it’s positioned far-off from all antennas (so long as you don’t put a GoPro on it). The CineFlow additionally has respectable placement, because the GPS is above the VTX antennas, avoiding sign blockage. Nevertheless, on most different quads, the GPS is positioned underneath the VTX antennas, which ought to nonetheless work however not optimum.

Worth & Total Worth

Lastly, let’s evaluate pricing and see what you’re getting to your cash. These costs embrace GPS, an ExpressLRS 2.4GHz receiver, and the DJI O4 Professional Air Unit.

.

I’ve to confess—I’m tempted to get the Axisflying Manta 5 SE, swap out the O4 Lite for the Professional, and both promote the O4 Lite or preserve it for a micro quad. However when you don’t wish to cope with swapping parts and simply wish to fly straight out of the field, the GEPRC Vapor D5 appears to supply the finest worth on paper. The iFlight Nazgul DC5 ECO can be priced moderately, nevertheless for $34 extra, it provides much less: ESC and BEC are weaker, the motors have decrease KV, and the digicam has no safety.

I additionally actually just like the design of the DeepSpace Seeker5, and its specs look implausible—however at $574, it’s a bit expensive.

As for the Nazgul Evoque and CineFlow, these are the solely quads over $600, and actually, I feel they’re a bit overpriced primarily based on their specs and design. For that cash, you could possibly get the Vapor D5 AND purchase an additional set of O4 Professional as backup!

Remaining Ideas – Which One I Am Going to Get

After weighing the professionals and cons, I’ve determined to go along with the GEPRC Vapor D5.

When it arrives, I’ll do a full assessment, together with:

• Tuning its PID and filter settings
• Seeing how a lot efficiency enchancment I can get
