Introduction
The rapidFIRE 5.8GHz Goggle Module is a high performance receiver designed for the FPV market.
Unlike traditional diversity receivers, the rapidFIRE includes sophisticated hardware which ‘fuses’
together the image from two antennas, and digitally reconstructs the image, with no additional
latency.
Designed to give the best possible video quality in indoor arenas where multipathing is a big issue,
and also in outdoor environments where maximum video range is required.
Anatomy of a rapidFIRE Module
The rapidFIRE module follows the FatShark recommendations for an Rx module compatible with both
Attitude, and Dominator goggle families.
Two SMA ports are provided, labelled in the User Interface as ‘Upper’ and ‘Lower’.

Installation Background
Module Power (or lack of)
Back when FatShark placed the first Dominator V1 goggles on the market, many moons ago, Mr.
Shark had the foresight to include an expansion bay to allow modules to be changed. This spawned a
whole industry in 3rd party receiver modules, covering not only the 5.8GHz band, but also the 2.4 and
1.3GHz bands.
What wasn’t foreseen was how power hungry 2017’s receiver modules would be, and that the
electronics in most of the goggles are not happy providing enough current to power these modules.
Depending upon the goggles used, the rapidFIRE may require an auxiliary power board in order to
supply power to the module.
Installation Details
For Attitude v3, v4, or Dominator HDOs
For these goggles, installation is plug-and-play, no aux power board required.
1) Remove the goggle rx bay door
2) Insert the module carefully into the connector, ensuring that it is not offset, or slid into the
gap between the connector and the goggle shell
3) Finish by attaching the appropriate goggle-bay door (noting of course that the Attitude and
Dominator use different doors)
4) Go Fly

For Dominator v1, v2, v3, SE, HD1, HD2, HD3
There are three ways to install the module into these goggles.
1) Using the auxiliary power board
2) Sending the goggles to a repair center to modify the power supply
3) A DIY modification to the Goggle’s power supply
Option 1: Auxiliary Power Board
The first method is the easiest, and can be performed using just the accessories shipped with the
rapidFIRE module. The Auxiliary power board is a replacement for the head-tracker board which is
little used in the race/freestyle world.
To install it, follow the procedure below:
1) Open the head-tracker bay door (opposite side of the goggle from the Rx bay).
2) Very carefully attach the end of the flat-flex cable to the auxiliary power board
a) First carefully slide the black part of the connector away from the body
b) Insert one end of the cable with the metal pads facing up, and slide the black locking
piece back to its original position
3) Install the aux power PCB very carefully into the head-tracker socket. Take great care to
ensure that the pins are correctly aligned in the socket. Misalignment here can create damage
to the goggles and/or rapidFIRE module.
4) Run the flat-flex cable across the front of the goggles, through the center of the FatShark
logo.

5) Close the head-tracker bay door
6) Carefully attach the other end of the flat-flex cable to the rapidFIRE receiver using the same
procedure described above.
7) Install the rapidFIRE receiver into the Rx bay
8) Close the Rx bay with the appropriate goggle-bay door
9) Apply the sticker (pick a color) to cover up the flatflex cable.
10) Go Fly
Note that to verify that the aux power modification worked, enter the main menu, and look in the bottom
left corner of the OLED display. If a voltage is displayed, the mod did not work. If no voltage is displayed,
then you are good to go.
Option 2: Repair Center Modification
Included here for completeness, but we don’t really expect pilots to give up their precious goggles for
a few days.
If you do wish to eliminate the auxiliary power board a simple modification to the goggles may be
performed by one of our repair centers, located in the USA, UK, and Australia.
To start the process, please send an email to [email protected] with the title ‘HDO Power
Modification’.
Option 3: DIY Goggle Modification
We do cringe a bit suggesting this, but given the fact that most pilots these days are fairly skilled with
a soldering iron, and have successfully been adding power switches to their dominators we will
suggest it anyway.
There is a fairly simple procedure to bridge one of the components that causes power issues for the
older goggles. Basically, this component was a power filter that was included for good engineering
practice, but was never really required.
Please be aware that any damage caused by opening your goggles to perform this operation is not
covered by your warranty, however, our network of repair centers can always patch things up if the
procedure goes horribly wrong (at your expense of course).
The procedure is documented in the User-Manuals section of our rapidFIRE product web page here:
