Reasonably priced Entry into Digital FPV
The Walksnail flagship goggles, the Goggles X, are priced at a steep $460. Whereas they’re the last word choice in the case of total efficiency for the Walksnail system, there are cheaper options such because the Walksnail VRX. Nonetheless, it has a posh setup with dangling cables and potential latency points will be deal breakers for some.
Enter the Walksnail Goggles L, a budget-friendly field goggle designed particularly for the Walksnail system, making digital FPV extra accessible than ever. Priced at simply $199, these goggles are a extra inexpensive different to different digital FPV goggles in the marketplace.
In reality they’re fairly much like the Fatshark Recon HD that was launched a few years in the past by way of specs and options, however that was discontinued they usually had been barely dearer. It’s good that we have now extra low cost walksnail choices.

Energy Necessities
Powering the Goggles L is versatile. The goggles settle for an influence enter starting from 2S to 6S, much like the dearer Goggles X. You possibly can just about simply decide up any frequent drone batteries with XT60 connector to energy the goggle.
The entrance cowl has an LED panel that lights up when powered on. It serves as a great reminder to unplug the battery and provides a technological contact to your gear. Nonetheless, it appears there’s no method to change the colour, however you possibly can flip it on and off within the menu settings.
Look, Person Interface and Controls
The Walksnail Goggles L function a white plastic housing with a matte end and a well-organized format of buttons and connectors for ease of use.
On the suitable aspect of the goggles, you’ll find a sequence of important controls.
- From the left, there’s the 5D Joystick Button, which allows you to scroll by the menu and make sure picks by toggling and urgent the button.
- Subsequent, you might have the Again Button for returning to the earlier menu or exiting the present mode. Nonetheless, the Again button doesn’t appear to work in my unit. I can return within the menu utilizing the report button, and the Again button merely doesn’t do something in any respect. I hope it’s only a bizarre bug they’ll fastened in future firmware.
- Subsequent, is the Report Button, which is meant for use to begin or cease video recording.
- Lastly, we have now the Hyperlink Button on the far proper, which lets you pair the goggles to a VTX.
On the underside of the goggles, you might have the three.5mm Port, offering head monitoring output. Adjoining to it’s the Energy Port (DC 5.5*2.1mm barrel connector), supporting a voltage vary of 6V–25.2V (2S to 6S).
On the highest aspect of the goggles, there’s a Warmth Dissipation Outlet for sustaining optimum working temperature.
The Micro SD Card Slot is conveniently positioned above the show space underneath the faceplate foam, permitting easy accessibility for storing and retrieving recordings. With a built-in Micro SD card slot, customers can simply report their flights.
For some motive they haven’t put any LED indicator on this goggles, so you must depend on its beeper to guess what state the goggles are in.
Lastly, there’s no USB-C port, so improve is completed by way of the SD card, and energy solely by the barrel to XT60 connector. There’s no video output to exterior show both.
Display and Menu
The 1080p screens look crisp and clear, offering excessive decision. That is adequate for the reason that Walksnail system helps as much as 1080p, and most customers favor 720p for higher stability and decrease latency. The interface and menu are an identical to what you see within the Goggles X.
Antenna Efficiency
One motive the Goggles L look so streamlined and clear is because of the built-in antennas. These patch antennas present balanced efficiency between protection and vary. Whereas particular beam width just isn’t supplied, the achieve is about 4.9dBi, and the antennas are LHCP.
These are directional antennas, providing higher vary when flying in entrance of your self however doubtlessly decreased efficiency when flying behind. You possibly can’t swap to aftermarket antennas, so these goggles aren’t designed for long-range flights or conditions requiring excessive penetration efficiency. They’re extra appropriate for indoor whoop flying or flying in small native parks.
Head Tracker Assist
Most individuals most likely gained’t care about head monitoring, however when you do, the Goggles L is for you. The top monitoring sensor, which makes use of a 9-axis gyro module, is built-in into the goggles to seize the pilot’s head actions. Paired with a gimbal, it sends alerts by way of the picture transmission system to regulate the digicam’s pan and tilt, offering pilots with a cockpit-like sensation. Caddx just lately launched some gimbals for this function: https://oscarliang.com/product-e5un
It additionally helps PPM sign output to Radio Controllers by way of the Goggles L’s 3.5mm headphone TX connector, which in flip outputs to the drone.
Consolation and Match
Walksnail excels in creating goggles that match effectively, and the Goggles L isn’t any exception.Using thick, good high quality polyurethane foam, the goggles’ face masks ensures softness and luxury whereas decreasing mild leakage for an enhanced sporting expertise. The froth is hooked up by velcro and is detachable.
The goggles weigh solely 351 grams and are comparatively comfy, though some mild leakage across the nostril space is frequent with field goggles. The supplied foam padding is ample, however hopefully, we are going to see another aftermarket foam and headstrap choices for these searching for a greater match.
One situation is that the highest of the goggles will get fairly sizzling after operating for about 10 minutes, even when not paired with the VTX. Heat air will get blown to your brow and eyes, which could turn out to be uncomfortable in sizzling summer time days.
Lack of Low Latency Mode
The Walksnail Goggles L come outfitted with 1080p decision screens operating at 60fps. This implies you gained’t have the ability to use the 100fps low latency mode accessible on the Goggles X, leading to about 35 to 40ms latency versus the 25 to 30ms latency of the 100fps mode.
Not for Individuals Sporting Glasses
The Goggles L makes use of a magnifying lens system, making the display seem additional away than it truly is, which helps scale back eye pressure. This setup is helpful for many customers, although these with vital imaginative and prescient correction wants would possibly discover it difficult with out customizable diopters. There’s no focus adjustment, and the goggles are too small to suit a pair of glasses whereas sporting them.
Based on my contact at Walksnail, they’ll customise lenses for customers, however they require a prescription. The customized lens is removable, permitting for the set up of nearsighted, farsighted, or blue light-blocking lenses to fulfill particular person preferences. They’ll’t present me with a price at the moment so it’s unclear how a lot they are going to cost.
I want they may present generic lenses with -2, -4, -6 diopters like Fatshark did, nonetheless after discussing with Walksnail they don’t appear too eager on doing that and insisted on a prescription.
For individuals who put on glasses, the Goggles X could be a extra handy choice as you possibly can regulate focus contained in the goggles.
Compatibility
The Goggles L is appropriate with all present Walksnail VTX fashions – VTX V1/V2, 1S Lite, Moonlight, and so on. Nonetheless, the Goggles L is strictly designed for the Walksnail FPV System. Because of the lack of AV enter and HDMI enter, you gained’t have the ability to use the Goggles L with Analog and HDZero.
Goggles X Comparability
Regardless of the totally totally different design, the burden and measurement variations between the Goggles X and Goggles L are literally extra comparable than I anticipated. With out battery, the Goggles X weighs 317g, whereas the Goggles L weighs 351g.
To guage the efficiency, I in contrast the Goggles L to my Walksnail Goggles X outfitted with unique antennas. Regardless of the Goggles L’s decrease body price, the efficiency was spectacular. The sign power and latency had been comparable when flying inside 300m. In some circumstances, the Goggles L maintained even higher bitrate (Mbps) and latency efficiency than the Goggles X setup, most likely because of the increased achieve antennas.
Buzzer Standing
The Goggles L doesn’t have any LED for standing indication, relying solely on the beeper.
