Hi!

I want to make myself a portable fpv system that I could use on multiple rovers (Easier to learn FPV on the ground when you have fear of heights like myself). I read many tutorials, watched many videos and think I figured out something I can build from parts I already have. It's a pretty basic system (Cam, transmitter and battery) and I mostly need confirmation my wiring is correct and I won't cause a short circuit and fry some of my parts.

The system will be powered by either 2s or 3s lipo batteries with a jst connector.
The battery will be plugged in a 2-Male 1-Female 3 Plugs Connector like this one:

One male connector for the camera. One male connector for the transmitter. One female connector for the battery.

My worry is about the video signal wire. It would be connected directly between the camera and the transmitter without an additional ground wire betweem cam and transmitter.

Would that be safe?

Yes gofrux, because they have common ground. If not, it would still be safe but it would simply not work. Without the additional ground wire you also avoid the risk of a ground loop, although that may not be an issue at all because the current draw is normally very low.

Some people use a ground wire (or coax) just for shielding. In that case you simply connect one end and leave the other end open.

Random Noob Question: How many FPV goggles can be set to observe a single camera before you have problems?

For instance, could one have a dozen people all watch their fpv view of flying (with goggles) without a problem?

If it's R/C, I'm in!

Absolutely. Since the goggles function as just a receiver, there is no limit... just as there is no limit to the number of stereos that can tune into a particular station/broadcast.

Thank you Martin for taking the time to reply. You have been a generous teacher to me.

Awesome, thanks for the reply. Seems like it could add a lot to the spectating experience at major events.

Finally got my FPV going on both my h8-mini and my Syma x5c.

I'm inclined to think people who aren't flying something FPV are wasting their time on earth. And those who don't at least give their kids a chance to get into are probably guilty of child abuse.

That's a hyperbolic way to say OMG THIS SOOO FUN!@#@$&$@

I was wondering if anyone could help. I bought a Quanum Nova FPV GPS Waypoint QuadCopter and wanted FPV so I bought,

Turnigy HD ActionCam 1080P Full HD Video Camera
5 Inch 800x480 5.8 GHz Little Pilot HD FPV Monitor With Mushroom Antenna And Bracket
Quanum Q58-6 40 Channel FPV Transmitter 600m
Multiwii MWC FC Bluetooth Module Programmer
FPV Live Video A/V Cable for Turnigy Action Cams

Could someone please show me by either a diagram or picture of where to put the wires for the Transmitter and Multiwii. Any help would be greatfull.

Thanks Rod

I just grabbed my second pair, they are simply too cheap, but work best in open areas

Hi, I have FatShark HD3's. I have an issue with the brightness, and contacted the FatShark support. They told me to ship it to:
Randy Ram
7267 Westhaven Pl,
Rancho Cucamonga
CA 91739
USA .
Does anyone know if this is legitimate. This is the support from fatshark.com. Any help would be appreciated.

One question: Does a dji mavic or phantom can parasit a conventionnal fpv signal?
Two times I crashed because of blackout and each time a stupid guy was flying with his mavic.
But when I scan the band on my goggle I can see anything because his signal is HD
