I'm getting into this stuff. Just bought a Spark by DJI. Woule love to dip into this FPV racing stuff. I dont have anyone local near me to train or learn from. So I'll have to do it on my own. But there are some things that I am looking for.

Advice on YouTubers to watch
An already built used unit or a new unit with parts list to make my own. I'm good with my hands, learn quick and hella dedicated(probably due from my military days).
I dont really have a budget(cuz once I get into something, i over spend anyways) but im looking at sticking around 500 or less on the actual quadcopter.

I may not know what questions to ask just yet. So beat me up and call me whatever(been called worse)

Thanks in advance!
