Design and Construct High quality

At first look, the SKY04X Professional could seem similar to its predecessor, but it introduces a matte end that each prevents fingerprints and reduces glare. This refinement is in step with Skyzone’s dedication to high-quality development and design, making certain the goggles not solely look good but in addition really feel comfy throughout extended use.

Accommodating nearly all of customers, the inclusion of two faceplates permits for a tailor-made match throughout various face sizes and styles. The diopter and IPD changes can be found, catering successfully to nearly all of customers.

In distinction to Orqa and Fatshark goggles, the Skyzone SKY04X Professional is provided with a receiver module (SteadyView V3.3) and primary antennas, providing first rate financial savings. Whereas this module possibly not fairly on par with top-tier modules like Rapidfire or TBS Fusion, it proves greater than succesful for the common consumer. The analog DVR now information at 60fps, marking a notable enchancment from the V1’s 30fps.

If you happen to’ve seen my assessment of the unique SKY04X goggles, you’ll recall they had been my most well-liked alternative for analog FPV goggles: https://oscarliang.com/skyzone-sky04x/

So what are the variations from earlier model?

The Sky04X Professional options 1080p OLED panels with a refresh charge of 100fps, presenting a notable enhancement over its predecessors and even providing a slight benefit over the HDZero Goggle‘s 90fps. Along with 720p 100fps HDMI enter, these goggles guarantee compatibility with excessive body charge methods, similar to Walksnail’s 100fps low latency mode.

Subject of View

The Professional boasts a 1920×1080 decision, 52° FOV with a local 16:9 side ratio, a considerable improve from the earlier model’s 1280×960 display and 46° FOV with a local 4:3 side ratio. Though each fashions are switchable between 4:3 and 16:9, the Professional model’s bigger FOV in 16:9 enhances the immersive expertise, significantly with widescreen digital video receivers.

Energy Button

A notable addition is the on/off energy button on the facet, simplifying the method of turning the goggles on and off with a protracted press, whereas a brief press turns the fan on and off.

Cooling Fan

As a result of upgraded shows which generate extra warmth, they’ve added a cooling fan to the bay in the correct. Meaning you not can use two receiver modules like earlier SKY04X.

Show and Person Expertise

The OLED shows ship pictures with placing distinction and vibrant colours, considerably bettering visible readability over conventional LCD or LCOS shows. Furthermore, the native 16:9 side ratio is a considerate change, aligning nicely with the widescreen desire of Walksnail FPV methods.

The standout characteristic of the Sky04X Professional is undoubtedly its 52° FOV. Nonetheless some customers would possibly discover blurry edges, which makes it onerous to learn the OSD/textual content on the corners. Nonetheless, when flying analog, significantly with 4:3 cameras, choosing 4:3 within the goggles successfully reduces the FOV right down to round 46° (with each side lower off), addresses the problem of blurry corners for me. If you choose 16:9 within the goggles when utilizing 4:3 cameras, your picture will seem stretched and distorted, which is mostly undesirable. For Walksnail cameras with a local 16:9 side ratio, selecting 16:9 within the goggles is advisable.

General, the SKY04X Professional’s controls and structure are designed for ease of use, that includes an intuitive on-screen menu system that enhances the consumer expertise.

Compatibility with Walksnail and HDZero

Regardless of being analog goggles, the SKY04X Professional provides assist for each Walksnail and HDZero methods.

Connecting to a Walksnail exterior video receiver, the goggles can function within the 100Hz low latency mode. Nonetheless, it’s not with out its limitations, particularly when used with HDZero’s lowest latency mode, as it may well solely obtain a 60Hz output. For these trying to the complete HDZero’s 90Hz expertise, this can be a downside and you might take into account getting the HDZero goggles.

An extra level to think about is the potential for added latency when utilizing these digital methods by means of the HDMI enter. Whereas it’s a minor concern, it’s value noting for individuals who prioritize split-second responsiveness of their flights.

My latency assessments, utilizing a GoPro 12 at 240fps, confirmed minimal variations between the SKY04X PRO and different high-end analog goggles when utilizing these digital methods. For freestyle flying and informal use, I discovered the latency completely acceptable.


One notable change within the SKY04X Professional is the elimination of “quadversity,” a characteristic some could miss. It is because you’ll be able to’t use two Steadyview receivers concurrently as one module bay is now devoted to cooling the shows.

The precise IPD adjustment measured about 60mm to 70mm, barely narrower than marketed. This is likely to be one thing to think about for these with IPDs exterior this vary.

Massive subject of view can introduce blurry edges and corners for some folks. An possibility to regulate zoom can be good, a characteristic that’s already accessible on the DJI Goggles 2.

The included primary dipole antennas are adequate for short-range flights however depart room for enchancment. For optimum efficiency, significantly for penetration and longer ranges, upgrading your antennas is advisable. I counsel a mixture of a directional antenna, like a patch antenna, and an omni-directional antenna, similar to a right-hand round polarized antenna, for optimum protection.

Compatibility with third Social gathering Receivers

For these in search of the very best in receiver efficiency, you’ll be able to improve the included Steadyview module to the ImmersionRC Rapidfire or TBS Fusion by swapping out the module.

One caveat: this would possibly require a 3D printed cowl to your chosen module. In my case, I needed to print a customized cowl for the Rapidfire for the reason that unique covers weren’t suitable.
