You can download a more detailed user's manual from Caddx download page .
Link button is used to bind(Link) VTX (drone) and VRX. Press by inserting a thin pin into the hole.
Record button is used to record the image displayed on the screen (goggles) with DVR function .
Back button and 5D button are used when operating setting screen displayed on the screen (goggles). Back button is used to return to the previous screen or to "cancel". 5D button is a joystick and can be operated in five ways: up/down, left/right, and push. Up, down, left, and right operations are used to move the cursor, and push operations are used to "select" or "determine".
Attach VRX to FPV goggles (the photo is SKYZONE COBRA X ) with included adhesive sheet. The adhesive is not very strong, so you can remove it whenever you like. You can buy similar gel double sided tape (Amazon.com) at your local store.
Power the goggles and VRX from power supply using bifurcated power cable that comes with the VRX.
Then switch the goggles input to HDMI.
Power on/offThis VRX does not have a power button. It starts when you connect power to the DC input port. It takes about 30 seconds to complete booting.
Switch the input on your FPV goggles to HDMI and you should be able to see the VRX main screen.
Application to national standards/switching modesWalksnail Avatar Goggle/VRX is set to SRRC mode when shipped from the factory. You must switch to the standard mode for your region before use.
Prepare a text file named "avatar_std.txt" in which only one number is written, and store it in the microSD card. Put it in the goggles/VRX and power on the goggles/VRX to set/switch the mode. In "avatar_std.txt", enter the number (0 to 3) in the table below for only one character.
If you download "FCC Unlock Procedure" from Caddx download page , you can get a template of "avatar_std.txt". The file "avatar_std.txt" can be left in the microSD card all the time.
|0||SRRC||China||4 channels available|
|1||CE||EU and others||4 channels available|
|2||FCC||USA||8 channels available|
|3||MIC||Japan||3 channels available, Transmit power fixed at 350mW|
Unlocking output powerWith Walksnail avatar goggles/VRX, you can increase the output power to 1000mW, 1200mW by following the unlock steps. However, in order to use this, it is necessary to check the radio law of the area where you live, obtain the required radio engineer license, and operate in a way that is not illegal. Also, increasing the output power will cause equipment to overheat, so set it carefully.
This function is mainly available in the applicable regions of FCC mode. Unfortunately amateur FPV drone pilots in other regions are probably not available.
To unlock, download "FCC Unlock Procedure" from Caddx download page and follow the instructions included in it, "UNLOCK PROCEDURE.docx". Store "avatar_pwr.txt" text file in a microSD card, set it in the goggles/VRX, and power on the goggles/VRX to unlock.
Bind (Link) with VTXWalksnail Avatar Digital FPV System requires binding (link) VTX (drone) and goggles/VRX before use. If you bind once for the first time, from the second time onwards, you can connect just by turning on both powers.
- When VTX (drone) is powered on, VTX LED will flash green.
- When you press LINK button on the VTX, the LED on the VTX lights up red constantly.
- Next, press LINK button on the goggles/VRX and immediately release it. A beep will sound and the bind (link) process will begin.
- Wait a few seconds and it will be bound (linked). Bind is complete when the VTX LED is solid green and the goggles/VRX stops beeping. Connected goggles/VRX should show the video from the camera connected to VTX.
Focus ModeWalksnail Avatar digital FPV system has a function called "Focus Mode" that secures the resolution in the center of the screen and reduces the resolution at the edges of the screen to reduce the amount of communication data. If this is set to "Auto", Focus Mode will turn on when the communication situation deteriorates. Despite the digital FPV system, it is possible to judge the communication situation from the image situation like analog FPV system.

Note: If you remove battery during recording or continue recording until battery is empty, you will end up with unplayable files. Be sure to press record button to stop recording before turning off the power or removing the battery.
Recording file format
The Goggles/VRX microSD card stores videos with filenames like "AvatarG0000.mp4". Each time a new recording is made, the 4-digit number part of the file name is incremented. Goggles/VRX do not have a calendar, so the date of the file is not correct, but a temporary date and time are given in chronological order.
The video track format is MPEG-4 AVC Level 4 High profile. The resolution is 1280x720 and the bitrate is 38.9Mbps. This MPEG-4 container contains only video tracks and no audio tracks.
Two files with the same primary file name and extensions of ".osd" and ".srt" are also generated at the same time.
A ".srt" file is a so-called subtitle file, and various information displayed on the main screen of the goggles/VRX during flight is written in text.
The ".osd" file is a binary file that stores the OSD image of the FC (drone).
Walksnail Avatar Goggles/VRX's Playback feature allows you to overlay this information and the OSD screen onto your video.
Playback on PC
If you use video playback software that can display subtitles, such as VLC media player on your computer, you can display the contents of the ".srt" file overlaid on the video (right figure).
Also, a tool to combine video files, ".srt" and ".osd" files into a single video: "walksnail-osd-tool" is available on github . It is convenient for uploading the screen of goggles/VRX to YouTube etc.
Playback menuIf you select "Playback" at the top of the menu screen, the screen will appear as shown in this figure.
(image is quoted from official user manual)
You can play videos recorded with DVR function on the microSD card inserted in the goggles/VRX. Move [5D button] at the top of the goggles/VRX up, down, left, or right to move the white frame (cursor). Push [5D button] to play selected video.
When "OSD" on the upper right of the screen is switched to ON, OSD screen and various information on the goggles/VRX main screen will be displayed over the video being played.
If you press and hold [5D button] while selecting videos, it will switch to multiple file selection mode, and the screen will show "Delete", "All" and "Cancel" buttons. Pressing [Back button] during multiple file selection mode exits this mode.
You can play/pause the video by pushing [5D button] during video playback. You can also rewind/fast forward by tilting [5D button] left and right.
Firmware upgradeFirmware upgrade procedure is published in Avatar system update procedure (PDF file) that can be downloaded from Caddx page . Firmware files are available on Caddx download page , d3vl and github page. If the firmware versions of the goggles/VRX and VTX do not match, a warning message will be displayed on the goggles at startup. However, the firmware of each unit does not always release the latest version all at once. Because of this, you may have to use it with a version mismatch.
Variety of firmware
There are 5 types of firmware for the Walksnail Avatar Digital FPV System, as shown in the table below, and each target device is different. Please be careful not to make a mistake when updating.
|1||Avatar_Gnd_xx.xx.xx.img||Walksnail avatar digital HD FPV Goggle, Fat Shark Dominator HD|
|2||AvatarMini_Gnd_xx.xx.xx.img||Fat Shark Recon HD|
|3||AvatarSE_Gnd_xx.xx.xx.img||Walksnail Avatar VRX|
|4||Avatar_Sky_xx.xx.xx.img||All Walksnail Avatar Transmitters (VTX)|
|5||AvatarMini_Sky_xx.xx.xx.img||Walksnail Avatar Mini 1s Transmitter (VTX) before version 28|
How to upgrade goggles/VRX
Make sure the battery is fully charged before starting the upgrade. If power is lost during a firmware update, the update will fail and the device will stop working.
- Prepare an empty microSD card and format it in exFAT format. Using the Goggles/VRX [Settings]-[Record Set]-[Format SD Card] menu allows you to format the microSD card set in the Goggles/VRX.
- Using a computer, store the firmware file in the root directory of the prepared microSD card.
- Insert the microSD card into microSD card slot of goggles/VRX and turn on the goggles/VRX.
- Once the goggles/VRX have booted, press Link button for at least 8 seconds.
- The goggles/VRX screen will then go black, a single beep will sound, and the update will begin. Release your finger from Link button.
- After a while, the goggles/VRX will begin to beep repeatedly. The update takes a minimum of tens of seconds to a maximum of about 10 minutes.
- After the final long beep, the beeping will stop and the goggles/VRX will reboot when the update is finished.
- After the goggles/VRX has restarted, do [Settings]-[Device]-[Reset All] from the menu. Then redo the necessary settings such as binding with VTX and specifying the channel number.
- Goggles/VRX firmware version can be checked by selecting [Settings]-[Device]-[Device Info] from the menu. You can check the firmware version in the "Goggle SW Version" column.
How to upgrade VTX
Make sure the battery is fully charged before starting the upgrade. If power is lost during a firmware update, the update will fail and the device will stop working. Also, please cool down the VTX (drone) with a small fan while updating the firmware.
- Connect the VTX (drone) to your computer with dedicated USB cable that comes with the VTX, and connect battery to VTX (drone).
Then a USB memory drive will appear on your computer, so store the firmware file here.
When upgrading Walksnail Avatar Mini 1s transmitter from version 28 or earlier, change the name of the firmware file from "Avatar_Sky_xx.xx.xx.img" to "AvatarMini_Sky_xx.xx.xx.img" before storing. Otherwise, it will be judged as unmatch firmware file (LED turn solid red) and firmware cannot be updated.
- Next, remove the VTX (USB memory drive) from your computer.
- After confirming that the VTX LED is flashing green or is constantly lit green (when bound with goggles), press Link button for at least 8 seconds.
Then the LED will turn off once and the update will start. LED flashes red during the update.
The update takes a minimum of tens of seconds to a maximum of about 10 minutes.
However, if you have stored a firmware file that does not match your device, the LED will turn solid red. In this case, remove the VTX (drone) battery and start over.
- The update is complete when the LED flashes green or changes to solid green.
- VTX firmware version can be checked by selecting [Settings]-[Device]-[Device Info] from the bound goggles/VRX menu. You can check the firmware version in the "TX SW Version" column.
Setting the OSD DisplayNot only immediately after assembling your drone, but also when updating firmware of the FC, it is necessary to redo the settings related to OSD display. Otherwise, OSD screen will not be displayed on the screen of goggles/VRX. Here, I will explain the setting method when using Betaflight (Ver.4.4) for FC firmware.
After setting, click "Save and Reboot" at the bottom right of the screen.
. Alternatively, if you enter "Avatar" in the search box on "Presets" screen, you will find the presets shown on the right. You may apply this.
After setting, click "Save and restart" at the bottom right of the screen.
Change OSD fontDownload the "FC osd fonts update" from Caddx download page and follow the included instructions "ReadMe.txt".
Open "font_update.ini" included in "FC osd fonts update" with a text editor, etc., and change it as necessary. Then store this "font_update.ini" and font file (.png) in microSD card and set it in the goggles/VRX. Start Goggles/VRX and select [Settings]-[Display]-[Font Update] to write font files to FC. Next, select [Settings]-[Display]-[Custom Font] and select "user_ardu" or "user_bf" to switch the font. Also, specifying this switches [Settings]-[Display]-[Custom OSD] to "Custom".
Font files are prepared for ArduPilot and betaflight. If you change this image file with a drawing tool, you can set the original font.
|1||user_ardu_24.png||Font for ArduPilot with screen resolution of 720p|
|2||user_ardu_36.png||Font for ArduPilot with screen resolution of 1080p|
|3||user_bf_24.png||Font for betaflight with screen resolution of 720p|
|4||user_bf_36.png||Font for betaflight with screen resolution of 1080p|
Connect Goggles/VRX to TV/Computer: Use as webcamThe HDMI output connector of Walksnail avatar goggles/VRX is Mini-HDMI(HDMI Type-C). A commercially available Mini HDMI to HDMI conversion cable (Amazon.com) allows you to connect to a standard HDMI (HDMI Type-A) input such as a TV.
Also, if you connect a device called " HDMI Capture Board (Amazon) " that has an HDMI connector for input and a USB connector for output to your computer, you can use the goggles/VRX as a web camera for your computer. And you can use software such as Zoom, teams, and YouTube to distribute it online.
