Success on the Ground with FPV

[wasper67]

Have you looked at this, http://fpvlongrange.com/fpv-repeater-system/ I been wanting one these I may just try it out for myself.

That is actually a VERY cool idea. Combine that with a 5.8ghz100mw video repeater and you can easily put your tx/rx on a long pole or on a tripod sitting on the roof of an SUV and then sit back in the shade on a comfy lawn chair while you drive around. Awesome!

It DOES introduce an additional point of failure for the whole system though, so extra care would have to be taken to fully test before you get too far out. (The advantage with ground-based FPV, you can test without the worry of a destructive crash!) But other than that, I really like this!

Now, the question remains, can we get these in the US?

My house backs up too a very large hill,so my thoughts were to cut some trees for a line of sight with this repeater that could be placed on top of this hill and also include a 5.8ghz video repeater, this would enable me to have a much greater range without walking to the top of the hill each time....Ok I am lazy, this hill is steep and it is a pain in the rear for carrying all the fpv gear up there so this might be the ticket.

Is there any rule of thumb about what cables to avoid being in close proximity to each other ? I did have my Mad Bull body open, with wires all falling out and ran the engine on a 6cell Nimh battery, and the Vtx/camera on a 2 cell Lipo. I decided to make up a cable in order to run everything from the Nimh battery, and while I was doing that little mod - I tucked all the wiresin to the body, and covered the open shell with some gaffer tape to protect things from mud/water a bit.

Everything works, but I notice when I increase throttle I get some breakup on the video signal. It seems to go away again once the engine reaches the desired speed - but until that point it's annoying. I was wondering if this was because a few wires aren't insulated vey well, and so are causing the issue, or if it's down to all running off the same battery.

Either way, is there a simple fix to try ?

Probably a good idea to sperate your motor/esc wires from your video system wires. I also use USB cable for what ever I can as it is shielded. You could also use alloy foil as a shield. Using ferrite rings and capacitors are handy as well. I prefer a seperate batt system for vehicle control and video.

I also recommend either twisting or braiding all of the wires you can in your setup. Prevents crosstalk and interference from other nearby wires. I personally braid ALL of my servo wires. It "keeps" better than twisting (no mechanical pressure to untwist), makes the wires stronger (spreads wire strain across all 3 wires), and reduces interference just as well as twisting does.

Cheers, I've moved the video gear back to it's own lipo, and things are happy again. I don't know if the fact it's an old brushed motor makes a difference. I've got no issues running my fpv gear on my tricopter all from the main battery - but different ESCs and motors.

did you ever use this? My understanding is that it can be used with a 2.4ghz setup and you plug your receiver into the repeater. So what goes in the plane? A uhf receiver?

If you want to use one battery for everything, try an LC filter. This will clean up your video.
