Inexpensive Entry into Digital FPV
The Walksnail flagship goggles, the Goggles X, are priced at a steep $460. Whereas they’re the last word possibility in the case of general efficiency for the Walksnail system, there are cheaper alternate 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 reasonably priced different to different digital FPV goggles available on the market.
Actually 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 have been barely costlier. It’s good that we now have 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 costlier Goggles X. You may 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 reminder to unplug the battery and provides a technological contact to your gear. Nonetheless, it appears there’s no option 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 characteristic a white plastic housing with a matte end and a well-organized format of buttons and connectors for ease of use.
On the proper aspect of the goggles, you’ll find a sequence of important controls.
- From the left, there may be the 5D Joystick Button, which allows you to scroll by the menu and ensure picks by toggling and urgent the button.
- Subsequent, you’ve gotten 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 file button, and the Again button merely doesn’t do something in any respect. I hope it’s only a bizarre bug they’ll mounted in future firmware.
- Subsequent, is the File Button, which is meant for use to start out or cease video recording.
- Lastly, we now have the Hyperlink Button on the far proper, which lets you pair the goggles to a VTX.
On the underside of the goggles, you’ve gotten 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 file their flights.
For some purpose they haven’t put any LED indicator on this goggles, so it’s a must to depend on its beeper to guess what state the goggles are in.
Lastly, there’s no USB-C port, so improve is finished 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 screen and Menu
The 1080p screens look crisp and clear, offering excessive decision. That is enough because the Walksnail system helps as much as 1080p, and most customers favor 720p for higher stability and decrease latency. The interface and menu are equivalent to what you see within the Goggles X.
Antenna Efficiency
One purpose 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 will not be 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 may’t swap to aftermarket antennas, so these goggles should not 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 in all probability received’t care about head monitoring, however in case you do, the Goggles L is for you. The pinnacle 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 digital camera’s pan and tilt, offering pilots with a cockpit-like sensation. Caddx lately launched some gimbals for this characteristic: 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 is not any exception.Using thick, good high quality polyurethane foam, the goggles’ face masks ensures softness and luxury whereas lowering mild leakage for an enhanced carrying expertise. The froth is connected 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 enough, however hopefully, we are going to see another aftermarket foam and headstrap choices for these looking for a greater match.
One challenge is that the highest of the goggles will get fairly sizzling after working for about 10 minutes, even when not paired with the VTX. Heat air will get blown to your brow and eyes, which could turn into uncomfortable in sizzling summer time days.
Lack of Low Latency Mode
The Walksnail Goggles L come geared up with 1080p decision screens working at 60fps. This implies you received’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 Folks Carrying Glasses
The Goggles L makes use of a magnifying lens system, making the display screen seem additional away than it really is, which helps cut back eye pressure. This setup is helpful for many customers, although these with important imaginative and prescient correction wants may 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 carrying them.
In response to 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 satisfy particular person preferences. They’ll’t present me with a value at the moment so it’s unclear how a lot they may cost.
I want they might 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 is likely to be a extra handy possibility as you possibly can regulate focus contained in the goggles.
Compatibility
The Goggles L is suitable with all present Walksnail VTX fashions – VTX V1/V2, 1S Lite, Moonlight, and many others. Nonetheless, the Goggles L is strictly designed for the Walksnail FPV System. As a result of lack of AV enter and HDMI enter, you received’t have the ability to use the Goggles L with Analog and HDZero.
Goggles X Comparability
Regardless of the solely completely different design, the load and measurement variations between the Goggles X and Goggles L are literally extra related 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 geared up with authentic antennas. Regardless of the Goggles L’s decrease body charge, the efficiency was spectacular. The sign power and latency have been comparable when flying inside 300m. In some instances, the Goggles L maintained even higher bitrate (Mbps) and latency efficiency than the Goggles X setup, in all probability because of the increased achieve antennas.
Buzzer Standing
The Goggles L doesn’t have any LED for standing indication, relying solely on the beeper.

The process is strictly the identical as different Walksnail Goggles: https://oscarliang.com/setup-avatar-fpv-system/#Pairing-Air-Unit-to-Goggles
Nonetheless, you do must replace the firmware on the VTX to the newest model to assist the Goggles L; in any other case, it’ll simply keep in binding mode.
Updating Firmware
The method of updating firmware on the Goggles L is equivalent to different goggles. See my tutorial right here: https://oscarliang.com/setup-avatar-fpv-system/#How-to-Replace-Firmware-on-GogglesVRX
The firmware file for the Goggles L is: AvatarLite_Gnd_xx.xx.xx.
Conclusion
For $199, the Walksnail Goggles L supplies stability of high quality, efficiency, and affordability, making digital FPV extra accessible to a wider viewers. Whereas they lack a number of the superior options and decrease latency of higher-end fashions, their efficiency is commendable, making them a stable alternative for these seeking to step into the digital FPV world with out a hefty funding.
