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.

Buy the Docking from:

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.

Conclusion

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.
