It really doesn't matter to me which control system it is. I just want something that is affordable that will get me that range I am looking for. About the antennas, how many do I need and should they be on the transmitter or receiver? With one of your helical antennas and that $60 transmitter/receiver combo, can I achieve 3-4 miles of range?

If you fly in a good location and aim the antenna properly, then yes you can. However, remember the range equation. Selection of a site, keeping the Fresnel zone clear, and aiming the antenna properly are essential and not easily understood until you've experienced problems with it. Experience gets you as much range as your equipment does.

Alright thanks for all the help. I really just wanted to get an estimate of how much it would cost to equip a plane with a camera and all the necessary electronics. I will probably buy a plane soon in the future but I will fly it some and get used to it before I buy any video equipment.

I did search the forums but didnt find the answer so forgive me if its out there somewhere. There is a guy in Brazil, has the nickname of Gabriel. I have seen some of his FPV flights and in one he passes through 2 car tunnels. I was under the impression that fpv needed some sort of line of sight for the antenna. Im amazed that he got through 2 reasonably long tunnels. Is he using something different from the usual gear?

Thanks

His ground station was positioned at one end of the tunnel... so his signal would be LOS while flying thru said tunnel....

Pretty sure that one was flown from a chase car.

The one I saw he hand launched it from the side of the road, didnt seem like a car chase but could have been. thanks for the replies.

The launch was from the middle of the road. Should be pretty obvious that
the ground station was in a car.

You would think common sense would cover "acceptable operating area and safe practices" ! but In many cases that is not the case

Power connector

Hi

Can anyone suggest best option what battery connectors are prefered to use in FPV? I see a lot of OSDs and current sensors use T-Connectors like these.
Maybe it shoud be pointed in document on first page wich connector is prefered for maximum compatibility.

I must say I like those T-connectors as they won't go loose easily.

But basically any kind will do, just as long as your plane will operate under normal circumstances using those connectors. I'd pay a little attention to what A it can handle, but that's about it.
