Sir, can you suggest some FPV camera that I can use instead of action camera(Go PRo)? Using only the video transmitter above and receiver, i cant find one. Also, will it same my video data?
Think about your gimbal its a gopro gimbal
Yes sir, just for testing purposes before I used the GoPro since its a bit expensive if it crashes 
Im planning to use this first: (without using the gimbal first)
If using the above 1000tvl camera, the only thing i needed is the FPV Receiver only?
If GoPro, I need FPV Receiver and FPV Transmitter Lead?
With this pack yes you only need a 5.8Ghz receiver
Thanks much. If in any case I will be transferring to GoPro, ill buy FPV Cable/Transmitter LEAD.
