this is such a niche market that unless your just trying to see and feel stuff, your gonna want to shop with one of the larger outfits, They have alot of different product and alot of support. readymade, urbandrones are a couple good ones. if you just want to see stuff in action and talk, find somebody in your area using, not selling. They usually have an opionion less biased and will be able to show you why they wished they'd have bought brandX
to find somebody, try fpvlab or rcgroups fpv section and see if anybody will let ya tag along. plane, train, car, don't matter, all uses a cam and a way to view the cam
