Introduction

FuriousFPV has done it again. Yes, once again.

They have just launched their third revision of their popular True-D Diversity Module, redesigned from the ground up, both in terms of sotfware as well as hardware. Apart from that it also incorporates new and surprising functions, which we're going to get into in this analysis.

 

New features

These are the new changes that have been made to the Furious True-D V3 Diversity Receiver System, compared to its predecessors:

  • Buttons: the "wheel" has been substituted by three ergonomic buttons, that are now more easily accessible, and allow us to configure the module.
  • Integration with FatShark goggles: we can now change the channel through the buttons in the goggles, without having to fiddle around with the module to do so.
  • Power on / power off of the module: the on / off can be caontrolles manually to avoid excessive battery consumption or innecessary overheat of the modules when not in use.
  • New antenna switching algorithm: the RSSI sensitivity has been improved, as well as the algorithm that selects the antenna, to get a clearer video feed.
  • Buzzer: the True-D V3 incorporates a small low power buzzer to get audio feedback when we configure the module.the True-D V3 incorporates a small low power buzzer to get audio feedback when we configure the module.
  • New distribution: the distance between the modules has been increased to allow more airflow in and letting the reciever modules cool appropriately. In the V3, each of the two boards contains one reciever (in the older versions one board had all the electronics and the other had the two recievers).
  • USB socket: there's an accessible micro USB that allows us to comfortably update the firmware, without needing a USBasp or an FTDI.
  • New firmware: the firmware has been optimized, enhanced and simplified, adding in some new and powerful features.

 

Features

Apart from the newest version's updates, here's a list of the specs / features of the True-D Diversity system:

  • Real Diversity System.
  • Smooth transition between antennas.
  • Raceband ready, even the new 5300MHz set of frequencies.
  • Multiple channel selection modes: autmoatic, manual and favorite channels.
  • Super compact.
  • Designed speciffically for the FatShark Dominator V2 and V3 (HD included).
  • Integrated LCD to allow for an easy use and configuration of the module.

 

Analysis

 

Hardware

The module comes well packed in a box, surrounded by foam, that protects the reciever and avoids it from moving too much upon shipment, and a small moisture-absorbing silica bag. It also comes with a translucent injected plastic cover, that fits right over the True-D V3 and sits in the goggles compartment very snuggly.

The installation is extremely quick, you just have to remove our old module and fitting the new one in the reciever bay in our Dominator goggles. Once installed in the goggles we can proceed to screw in the antennas

 

Software

The firmware of the module has been completely redesigned, only using the screen to show the most relevant information. When we plug the battery in, the module shows the splash screen with the FuriousFPV logo, but the modules are turned off, with the intention of saving battery. In order to get the receiver up and going we'll need to press the button and it will then show the menus and the recievers will start working.

Some LEDs will indicate which antenna is being used: red for the upper antenna and blue for the lower one. A very simple visual indicator that complements the standard signal quality bars shown in the LCD display.

The main menu consists of 4 sections:

  • Working Mode: our favourite channels will be listed here, and we'll be able to select them through both the buttons in the module and the ones in the goggles.
  • Manual Mode: this screen shows us the 4 bands and their corresponding 8 channels; in this menu we can go through all the available channels and we can set any of them as favourite by simply holding the middle button for a few seconds. This way we'll be able to select it later in the Working mode menu. To remove them from that menu we simply need to press for a few seconds the middle button, and we hit Delete. As a curiosity, we can quickly change the band by holding the top or bottom button for a few seconds.
  • Smart Search: this mode sweeps through all the frequencies and it shows the ones that are closest to the transmitting frequency of our VTx, without having to do it manually. Just as in the last case, we can save the channel to later get to it quickly through the Working mode menu.
  • Band Scanner: this mode scans all the frequencies and it shows us a graph of the different signals in the spectrum.
  • Setting: inside this menu we have different configuration points: Alarm: to configure if we want the buzzer to alert us when the recieved signal is too low. Time Up: if the reciever has been working for longer than the timer has been set, the buzzer will alert us of it, whic is an ideal feature for those that tend to forget. New_F: you can configure any channel from 5000 to 5999MHz. Super useful for the new bands around the 5300MHz. Sign: the name that will appear under the signal strength bars in Working Mode, only a tag. Filter: the level of filter that we want to apply to the recieved signal. It's hoghly recommended not to change it unless you're doing long range (we're going to change it to Low) or if we predict the antenna switching will be constant (for example, in proximity flying we'll have to select High). The default value is Normal. Calibrate: calibrate the level of useful signal regarding the noise.

This is the official FuriousFPV video showing all the new stuff and how to use:

As you can see in the pictures, the new menus take advantage of the full display, making for an easier menu navigation and making it even more user-friendly.

 

Field Test

We didn't want to leave this article without any video, so we've prepared a comparison between the new True-D V3 and its predecessor True-D V2. Both are in the same configuration. We've used an ImmersionRC SpiroNET Omni and an 8dbi SpiroNET patch, also from ImmersionRC, with a 45º adapter. The patch antenna is highly directional, while the omnidirectional antenna has a good range in all directions, making the best use of the Diversity capability. Here are the results:

Pitifully the conditions were extreme: indoor spot, multiple rebounded signals and fadings due to the huge columns. This are the reasons why we can't see a clear conclusion about the performance...

 

Conclusions

They revolutionized the market with their first version thanks to its compact format. They later came out with a version with minor cosmetical changes and very little hardware updates, but a very good firmware version. But finally, this new release of the True-D V3 by FuriousFPV is even closer to perfection.

Some very good news are that Furious has kept the price the same as the older version. In addition to that, the pack includes a 45º and a 90º adapter which we can put to our antennas. You can get it right now in the FuriousFPV website (link below):

And we're sure that most current users will be wondering: can the V1 and the V2 modules be updated with the newer firmware? The answer to that is not yet! So FuriousFPV is currently working on a specific firmware for the V1 and V2 modules. The V3 firmware can't be used due to the storage limitations in the older versions. So, let's wait a litle bit more ;)
