WLToys V303 + GoPro 3 FPV conversion

I already have a WLToys V303 quadcopter and a GoPro Hero 3 camera. I would like to try to add FPV to this setup, but I am a bit confused as to what extra kit I need to buy. I like the look of the F408 4.3 inch FPV monitor, but I’m not sure what transmitter/antennas are compatible, and whether I need any other kit. Any advice gratefully received.



I have now received my fpv kit, but have ended up with a cable to connect to the GoPro, another to connect to the TX and a third to connect to the drone power. Unfortunately they all have different connectors. I am unsure how to go about wiring the all together.
