Mischa showed us how he upgraded his Attitude V2 Goggles with a Diversity video receiver module, that is designed for the Fatshark Dominator V2/V3/HD. He also added a faceplate on this pair of goggles.

Back when I bought my Fatshark Attitude V2, they were a great pair of FPV goggles. Actually – they still are. But unfortunately the built-in video receiver doesn’t support Raceband, and I am tempted to try the new diversity VRX for better signal.

You can’t replace the internal VRX in the Attitude V2 very easily like the new Dominators, as it’s built-in. Of course I could just buy/built a ground station (external VRX) and plug it into the input of the goggles. But I like the convenience of just flying wherever I am without setting up a bunch of stuff.

That’s why I did this DIY hack, and upgraded my Fatshark Attitude V2 with a Diversity Raceband VRX module – and while I was at it, I added a faceplate too.

The whole procedure was not too difficult but requires some good soldering skills, so this is not really for beginners.

The parts used:

• Fatshark Attitude V2 (check out our list of FPV goggles)
• Fatshark FSV2444 32ch 5G8 Diversity Receiver
• Fatshark FPV Goggles Faceplate (compatible with Dominators and Attitude)

Update (24/05/2016): Many thanks to Jeremy (ModifyRC), Ward Paterson, and a few other good people informed me that the Fatshark FSV2444 Diversity module actually perform quite poorly, something to do with the signal switching software and all RX have been called back. Maybe not a good idea to purchase this module just yet :)

1. Take the goggles apart

First off, we need to get to the board that has the module on it. Take off the contrast/brightness button and store it in a safe spot, it’s just pushed on.

To open the case take off the two stickers (CE and FCC) on the bottom of the Fatshark behind which you will find holes with one screw each.

Unscrew those, take them out and keep them save. Then take off the eyecups. If you do not want to add a faceplate, unhook them only on the top – they are kinda difficult to get back in.

Now you can carefully take the two halves apart starting from the side that usually touches your head.

There is a useful video on Fatshark’s Youtube channel.

2. Remove the VRX Module

The case is open, now take the receiver module together with the board it’s soldered to out of the case. You will have to unplug two cables then it’s out of there.

3. Desolder the Receiver module from the PCB

The receiver is soldered to the board on 3 points – and through the 8 pins of course.

The easiest way I found to unsolder the pins is getting rid of the plastic on the receiver side, then heat up the pins quick and hot (380C with a big tip) and pull them out the other side once they start moving. That’s usually within a couple of seconds.

Make sure you have fresh solder on the tip and do not touch the pin until it moves – or it won’t move because you take the heat away through the pliers. Also let it cool down between pulling every other pin, you don’t want the board to get too hot.

Once you’ve gotten rid of all the pins, heat up the 3 remaining points one after the other and either de-solder them with a pump or heat one up, move a screwdriver between the board and the receiver to push them a little apart and do that with all of the points a few times until the receiver falls off the board. The hardest part is done.

Now clean up the board/pinholes, align the new receiver and solder the new pins onto the board.

4. Drill extra hole on the goggles case

Depending on the module you are going to use and the way you want to use it, drill a hole or two into the case for the second SMA (in case of the diversity module) or for switching bands.

For the diversity you will need another 1/4” hole that is a little longer because of the installation angle. Luckily the diversity module comes with a drilling template. ;)

Plug in the cables and push the board back in place. Make sure you push it all the way down so the headphone jack sits flush and the switch for the internal/external module is usable.

Put the halves of the case back together, starting at the front. Screw them back together and re-attach the headband. Done.

5. Faceplate Installation

Want it to sit better on your face? Get the Fatshark Dominator Faceplate (available in both white and black), put some thin double-sided tape underneath the fan and push it in place. Its a perfect fit and super comfy.

The Attitude V2 (and probably the other Fatshark too) are a perfect fit on the left side of the FrSky Taranis Case with a couple of Antennas.
