Starting out on FPV

Hey guys! New to the forum! I am trying to make a very budget FPV set up for my RC airplane, something I can use around our land and am not super particular on fine video quality (I do want to be able to fly by FPV) but i am kinda lost on the whole process of FPV. The list of items below is kinda what i have settled on for my budget and i was hoping you guys could tell me if i have everything needed and which combination would be the best. Thanks!!

VTX


Camera


FPV screen



Antenna





I know what I would like........ But alas the wallet says "NO" lol

Thanks again guys!!!

1. You must decide on which model you will put the FPV on. 2. The useful weight that your model can carry (to calculate the weight of the battery and the weight of the camera transmitter). 3. We select the equipment. For convenient viewing of FPV, you can buy a receiver and connect it to a tablet, TV, video glasses (you also need to decide on this). I'm watching videos on a car TV and fatshark glasses. Start with: I have a flying model......

I use camera + transmitter on models with a 60cm span. Up to 2 kilometers of video is normal. For longer-range flights, I have 2 sets of 900-1200 MHz.

what part of the fpv do you recommend investing the most?
Antennas, they are by far the most critical part. You need to understand how they work.
If you want to race or fly close to things, like flying through the trees. Latency is going to be critical, that is, how long is the delay before the image can appear on the screen. If you are flying high, just enjoying the view, latency doesn't matter as much.

Here is the first of eight videos that helped me learn the basics of FPV.

so I want to fly BY fpv so latency is going to be critical. Am I right in thinking that 5.8ghz is analog and 2.4ghz is digital feed? and the digital feed has less latency?

So is the part of the setup that determines whether its analog or digital feed?
You are quickly getting beyond limits of my knowledge.

I believe the difference between analog a digital lies in how the signal is incoded. Analog signals are transmitted similar to a sine wave. The shape and amplitude of the wave determine the image. Static is the result of the environment on these waves. Digital signals are somehow converted to numbers. The numbers are not prone to change by the environment but they can be lost. So no static but you get pixilation when a number is lost.

With analog, you don't need to worry about compatibility, all the brands work with each other. Different brands of digital equipment are NOT compatible with each other.

Start with 5.8 FPV. It is inexpensive to eat . Then you can go straight to the Raspberry pi 3 b plus projects. For a beginner -easy firmware and connection + excellent video quality.But it is EXPENSIVE.
I immediately give the links without your questions. AR271 requires you to buy 2 pieces. For firmware, you need 2 8-16GB micro flash cards.

Oh sorry, I meant is it the VTX or the Antenna which determines whether its analog or digital, or what is it?

The digital system I believe does something with the image before it sends it Vs the analog which just sends it thus making it a poorer video quality.
