Review: FuriousFPV Dock-King Ground Station

by Oscar

The Dock-King from FuriousFPV is a ground station that houses the True-D diversity module. It uses better algorithm to improve video signal from the True-D receiver module.

The DockKing doesn’t have the internal receiver, you have to install a receiver module on it. At the moment it’s compatible with the True-D V3.5 module and V3.7D firmware (Not the V3.7). I was told that it’s compatible with other receiver modules too, such as the Pro58 and Rapidfire, however I am unsure if the performance is optimal though.

According to FuriousFPV, the Dock-King ground station enhances the performance of True-D module thanks to the special algorithm. This isn’t a plain break out box, it actually has a totally different menu system that allows for some very useful functions.

What’s special about the Dock-King ground station?

In 2018 I swapped out my True-D module for the Pro58 with Achilles firmware, and it’s been sitting on my desk since. I am glad I can make good use of the True-D module again with the Dock-King! Besides, I’ve always wanted a ground station that sits on a tripod for mid and long range flying.

It’s almost inevitable to turn your head while flying FPV which can mess up antenna orientation on the goggles. With the Dock-King ground station you can rest assured that the antenna orientation is always at its optimal position.

There are a few other great features that come with the Dock-King, such as HDMI output, lap timers etc.

Spec and Features of the Dock-King

Here are the important features and spec I simplified for you:

  • Supports 2S to 4S LiPo input (7.4V – 16.8V)
  • New RSSI algorithm improves signal quality compared to the standalone True-D
  • Output port for external DVR with improved DVR quality
  • Full OSD (data overlay) for real time RSSI monitoring
  • Supports bluetooth, allows configuration using smartphone
  • Built-in beeper for warning
  • Built-in Tripod Mount
  • Dual AV output ports
  • Output port for HDMI devices, such as big TV screen and broadcast

I was hoping the dockking had an integrated DVR, but it doesn’t. Furious will make an external DVR module which you can buy separately. And supposedly it will have much better image quality than the Fatshark built-in DVR.

However the DVR is pretty well designed from what I hear. It only records when it has signal, and it stops when it sees static so you don’t get huge files full of nothing.

The two AV video outputs and HDMI output allow you to share the video to the pilot, spotter and spectator screens at the same time without additional hardware. This can massively simplify the wiring in a race.

The most appealing feature to me is the possibility of daisy-chaining it with another dock(s) and get multiversity (more than diversity). It can use an Ethernet cable up to 100m long so you can set this up to fly in places full of obstacles. Just imagine the possibility!

There are two LED arrays on the back to indicate signal strength of each antenna.

Does the Dock-King make a difference to the True-D?

Here I am comparing the True-D’s performance to the DockKing with a True-D installed, see if it makes an improvement at all.


I feel like the Dock-King is designed for racers. Those fly long range will also find it useful.

There is definitely an improvement in the True-D’s performance when using it with the Dock-king ground station. And if you ever do “Stevie Wonder” when flying (moving your head with the flow), you will also appreciate having the antennas fixed on the tripod :)

Don’t forget all the additional features offered by the Dock-King, especially the possibility of “daisy-chaining” multiple dock-king to cover a wider area.

However, it’s not cheap at all, and it requires an additional receiver module to work. Too bad DVR/HDMI modules are not even included.

Hi do you think dock king will ever be able to be updated to work as well as rapidfire. thanks

Oscar 15th October 2019 - 5:06 pm

Nope, the technology is different. Rapidfire uses more advanced hardware.

Just curios why you think it’s not cheap. I’m not rich, $88 is nothing to sneeze at, but compared to prices on many other tech in our hobby, a unit that does that much to help our video signals and is sub $100 is a great price. Also, you said you’d need 2nd receiver module, why? I use the DK most often, but if I just want to run outside and test a quad, the module pops out of DK and into Fat-Sharks in about 25sec. Lastly, other modules will work normally on DK, with one disadvantage. DK uses a special algorithm, that is supposed to be sort of like the integration that Crossfire uses, that algorithm ONLY works with Furious modules. So I imagine a Crossfire on the DK would be totally flyable, but a True-D would have less break up and tad better picture.

It did nearly nothing to the signal in my testing, seems like it’s just a PCB to break out the pins. Tell me again $88 is cheap for what it does?

Thank you for this post! Very informative.

Did you figure out, if the rapidfire module is compatible with the dock-king?

Thank you!

Oscar 21st March 2019 - 8:14 pm

Yea it works, but it’s not recommended for best performance.

TJ 26th February 2019 - 4:15 am

Thanks for the info, any clue if after you flash the dock king firmware to the module can the module still be used in my Fatsharks or do i have to re-flash back to the goggle firmware?

tj 28th February 2019 - 3:31 am

I found the answer and you can use the module in your goggles with the dock king firmware with no issues only the loss of the find model function.

Oscar 11th March 2019 - 3:30 pm

According to FuriousFPV, you should re-flash the module to the goggle firmware for maximum performance.

As asked before………
how would you go about daisy chaining them as this would be a much more economical way other than having to use a antenna tracker??

lee 12th August 2018 - 12:27 pm

how do you daisy chain a dock king?

Mad Monkey 23rd June 2018 - 12:05 pm

this now supports a big range of receivers!!!

Oscar 30th June 2018 - 2:20 pm

it’s interesting, because someone asked ImmersionRC and they are not sure if that’s the best thing to do. It might work, but receiver modules outside of FuriousFPV are not intended to be installed on the Dock-King, so there is no guarantee it will give you they result they are designed to give.

Phil 29th July 2018 - 11:06 pm

It will so cool if you could make a video about that ?

Achim 6th June 2018 - 8:42 am

Could you please try your Achilles Module in the Dock King?

Oscar 12th June 2018 - 2:00 pm

it’s not supported. Only True-D.

Raymond Kerr 31st May 2018 - 5:28 pm

is there anyway to use the DVR within the fatshark goggles when the True-D is installed to the Dock King ?

Oscar 5th June 2018 - 2:28 pm

Yes you can.

onclefly 31st May 2018 - 3:58 pm

Hi Oscar, I wait your test. ;p
