I have a FS dominator basic reason didnt buy the built-in VRX because the VRX is expensive while the China made VTX/VRX is cheap like nothing and FS VRX not compatible with the cheap one, so I decided to make my self one for my FS goggle

UPDATE:

10/07/2012
Initial testing was not good, range is awful even with my Clover leaf antenna i think it less than 10 ft, I will need to change the antenna mount which I have already receive from ebay.

Got new RX from Foxtech every is soldered up, Initial ground test seem fine gonna do more test at the field!

09/10/12

Test was successful! after 20 flight the vrx work as i wanted it to!

Part list

- Header pin (need 9 pin)
- Perf board or some shop call this donut board
- PCB Mount SMA male for the VRX note most 5.8ghz use RP-SMA making it to use SMA mean you have to make your own antenna or use a converter
- VRX of course ebay sell the in pair which is recomended! as $22 for a pair!, but Foxtech sell the VRX for $15

I have not tested it yet as my VTX is broken once I get a new VTX or soldered the bare VTX modules I post the result,

Now maybe picture of the build log will give some interest

the parts


no pcb mount yet so i use the one from my broken VTX



Test fitting the component :

Look nice enough

Hi Skellator,
I too am looking to do this mod and have ordered the parts. Sorry to hear that you had poor reception after doign such a nice job of the build. Looking at your photos though, I wonder if you have soldered your connections on the wrong side? If you look at this other thread with similar mod, he reports some success. Anyways, I may be wrong as I haven't tried this myself yet, but thought I'd just share my observations from the photos.. Maybe your range could be inproved by relocating the soldering?

Good luck

my soldering are correct the modules silk screen are not printed properly that why you see it like in the picture , my initial suspect is the antenna mount waiting for some new mount

Aha Cool! I see what you mean now on second review of your photos. Maybe your module is bad?

Also I have read some reference to needing a capacitor, and then not needing it... google rx5808 fatshark and you'll find some info on fpvlabs...

Anyway, hope you get it working the way you want to. I will try the same soon (when parts arrive). I'll let you know how I get on.

I have another RX to test it again i might solder that one
