Imagine Fatshark released a new goggles even before Orqa could get their FPV.ONE out of the door. Well, that might be happening! Fatshark just announced their next FPV goggles, the HDO2.
The new Fatshark HDO 2 is going to replace the HDO (Aug 2018). They are clearly coming after Skyzone’s SKY03O, especially the Qrqa’s FPV.ONE as they have the same screen resolutions. The HDO 2 will also provide better support to the Byte Frost system with its 1280×720 resolution and switchable 16:9 aspect ratio.
Before we begin, don’t forget to check out my FPV Goggles Buyers Guide to learn all the technical terms.

Fatshark HDO2 New Features
Here is a list of notable features of the Fatshark HDO2:
- Upgraded OLED screens
- The revolutionary power button !
- Adjustable focus
- Integrated Fan Control
- Adjustable Fit Faceplate
- Supports 2S and 3S LiPo Input (7V – 13V)
Power button to turn the goggles on and off without unplugging the battery.
Adjustable focus to replace diopter lenses, designed for those who wear glasses, covering the +2 to -6 range.
Integrated fan control for adjusting fan speed level and switching the fan on and off with a button I presume. There is a DIY fan control mod for the older Fatshark goggles.
The HDO will come with the carrying case, lens cleaning cloth and a 2S 18650 case (same one you can buy from Fatshark).
User Manual Leaked (29 Oct 2019)
The Fatshark HDO2 manual was leaked on the internet. From the manual we learned a lot more about the HDO2 specs and features.
- FOV: 46°
- IPD: 54mm – 74mm
- Focus: +2 to -6
- Aspect Ratio: 4:3 and cropped 16:9 selectable (TBC)
- Resolution: 1280×960
- Supports AV input and HDMI input
- Supports Audio output
- Input voltage: 7V-13V (2S/3S Li-)
- Power Consumption: 320mA at 7.5V (no RX module), 770mA at 7.5V with Rapidfire
- DVR supports SD cards up to 32GB
- DVR record bit rate 6Mbps, MJPG compression, 30FPS, in AVI file format
- DVR is upgradable via SD card

The OLED panels in the HDO2 has the same resolution as the ones in the Orqa FPV.ONE. I expect them to have matching performance, however we don’t know if they offer the same image quality at this stage yet.
Buttons, Ports, RX Module Bay
The power modes might be confusing for some. According to the manual:
The HDO2 is shipped in Legacy Mode (like the HDO, HD3 and all older versions).
If you connect a battery to the HDO2, it will automatically power on and it will power off when the battery is removed. A short press of the Power Button will turn on and off the fan while in this mode. If you hold the button, the HDO2 will continuously beep to remind you the headset is in Legacy Mode and the goggles will not power down.
If you want, you can change the input power to use the Power Button to turn on and off the headset. To do this, you need to remove the Expansion Bay door and move the power mode jumper from Legacy Mode to Button Mode as show below.
While the headset is in Button Mode, a long press of the power button will turn on and off the goggles, while a short press will change the fan speed.
Note that Fan speed is proportional to the input voltage. If the headset is being powered from a 2S battery, maximum speed is recommended, and we recommend lowering fan speed if using a 3S battery. The low battery alarm also exhibits different behaviors for 2S and 3S. It is designed to work for 2S and may not provide much warning for 3S. We recommend not relying on the low battery indicator if you are using a 3S source as it will provide a very limited time window in which to return and land safely.

HDO 2 vs. HDO
At first glance, the HDO 2 might look quite similar to the the HDO, but there are some changes/improvements.
First of all, there is now a power button that many people have been asking for. It’s not only responsible for turning the goggles on and off, it also controls the speed of the fan (two levels). However it comes with something called “legacy” and “button” mode, which is slightly unnecessarily confusing for the users in my opinion.
Faceplate is smaller, and the fan is now powered directly from the barrel connector (no longer need to plug in the 2S balance port), and the fan turns on as soon as you plug in the battery. However you can’t turn the fan off, though the fan speed can be turned down. Note that the maximum speed is proportional to the battery voltage, e.g. on 3S the fan is faster than being on 2S. The face plate foam pad quality is similar to that of the HDO, also fake leather.
The most noticeable change is probably the optics, which are now circular instead of rectangular like all the older Fatshark models.
Fatshark also managed to extend the IPD range, between 54mm and 74mm. That covers an even wider audience, and it helps to minimize blurry edges. Due to the housing design of the older Fatshark goggles, the minimum IPD was limited around 61mm (I know they claim to have 59mm minimum IPD, but my own measurement is 61mm). Quite a few people complained they couldn’t get the whole screens to focus due to this. Now that shouldn’t be a problem anymore, assuming the number Fatshark provided is accurate.
The focus adjustment is another awesome feature, it basically moves the optics in and out independently so both your eyes can get the best possible focus. However that also means you can no longer use dipoter lenses in the HDO 2. If you have astigmatism, or if you have eye sight outside of -6 or +2, then you might have trouble using these goggles.
Anyway, with both the focus adjustment and narrower IPD adjustment, I suppose most people would be able to fully enjoy the larger 46 degree FOV without much blurry edge, which is amazing if you never try larger FOV like this before.
The locations of the buttons and connectors remain more or less the same.
The DVR in the HDO2 is still the same old DVR you get in the HDO and their older Dominator goggles, which is slightly disappointing to be honest. They are using better quality DVR in their Recon 3 (a box goggles made by Fatshark), and there is the PowerPlay (an external DVR), it’s slightly annoying they aren’t using any of these newer technology in their latest flagship FPV goggles.
Regardless, the Fatshark HDO 2 is definitely better than the HDO in every way: the improved OLED panels, the wider field of view, the ability to change screen settings, the ability to adjust the focus, the wider and narrower IPD. All of these at the same price as the HDO.
HDO 2 vs. ORQA FPV.ONE
Here are some of the major differences between the Fatshark HDO2 and Orqa FPV.ONE FPV goggles.
|Aspect Ratio||4:3 (native), 16:9||4:3 (native), 16:9|
|IPD||54mm – 74mm||56mm – 74mm|
|Focus Adjustment||+2 to -6||No|
|DVR||Old (30fps, 6mbps)||Better (60fps, 18mbps)|
The Orqa is more expensive for sure although the specs of the OLED screens and field of view are similar. But you do get more features with the FPV.ONE, for example HD DVR, OTA firmware updates, head tilt alarm, auto standby, and FPV.Connect (a feature that enables you to broadcast and live streaming your flight on social media.
We will have to wait and see what kind of user experience the Orqa brings to the table when it comes out for a more thorough comparison.
