fpv setup

Hello all! As I said before in the title, I want to buy a FPV Setup for my plane which at least 1km of range. I saw this one, and I think it's good enough. It has a 600TLV 1/4 camera and a Eachine VTX03 Transmitter with a modified antenna (if I buy it, I won't change it). I don't have any FPV...

Heya so im still unsure of what i want for FPV, I need a setup to work with a 2.4ghz transmitter, and idealy i would like 1 mile of range reliably, and it idealy needs to be super reliable, so i can just lug it out with me and it works, quick and easily. I have around £250 to spend and not sure...
