Definitely on one hand thats a very cool bit of footage and on another level its completely irresponsible. Im flying quadcopters and the fear of hitting someone would stop me trying that

Noob electronics question - I want to power 3 devices from my ground station battery (5000mah Lipo).

1. Video receiver
2. Goggles
3. Video capture device (as yet dont know what to buy, maybe pinnacle)

All devices require 12 volts.

How do I wire this up? I know very little about electronics. Serial, parallel, something else? Need fuses? Want to keep it as simple as possible. Could someone draw up a quick diagram. Thx in advance.

Simple, just connect all the positive wires of the devices together and all the negative one together and attach them to your lipo. Easy as that.

Basically like an octopus. This is called connecting in parallell.

Thanks. It says "Tuned for 910MHz" so is it specific to the channel or would it work across all 4 channels the Tx uses?

It will work with all channels, but works best at 910MHz. If you want one tuned for a different channel I can make you one. I have been making those antennas for quite some time now

Great thanks. I can certianly run on 910 anyway, was jsut curious. Looking to replace the stock antenna which seems to have somethig loose in it anyway.

Or perhaps I can make one if I had the wiring. Could I rip the stock rubber duck antenna apart and jsut use that for the lead to the V antenna part? I can put together the V ok I suspect, it is just using solid core wire correct?

Cheers thx for that. I might end up using two sets of EC3 parallel connectors then. My soldering skills are poor

I have made a few 5.GHz Vees, but I really don't like to do it as the tolerances are very tight. However, I do make cloverleaf antennas at 5.8GHz. These are circularly polarized. If you use one, it is best to have a circular antenna on both the TX and RX.

Sadly, you really can't do much with the stock antenna except extend it to the proper length after removing the internal spring.

Alex,
is there a page or site giving more information on orientation/radiation pattern for the V antenna? I picked one up from ReadyMade, as well as a standard patch. They suggest the nose of the aircraft but don't specify horizontal or vertical.
For some reason I would have expected "point down" like traditional wire landing gear on a slow stick.
Thx!

Two channel video question?

Well you all have pushed me over the edge

I have been a spectator for years contemplating getting back into RC. Then a few months ago I stumbled across an FPV video on Youtube. I'm hooked!

I have an Easy Star on the way and an Arducopter under construction on the workbench. It will be a while before I actually fly FPV but I am allready tinkering with design ideas. I have run into one question that I have not been able to find a good answer to:

I would like to have two fixed cameras in my bird. One looking forward for FPV and one in the belly for a straight down shot. I am having trouble finding a good solution for a two channel video system. I am a licensed HAM so I am open to solutions that require ham license.

Suggestions??

Thanks Everyone for the wealth of info you have made available on this forum!

Stephen
