Basic FPV
If you want to try fpv it can get expensive fairly quickly so before you buy a load of expensive radio gear get yourself a cheap system like this. A lot of RC suppliers sell a beginner kit that has everything you need to get started and for the most part you can replace each part with more expensive gear as you go along.
it doesn't have to be an expensive one, they are available from around £10 and they make FPV a whole lot easier.
