That clone chameleon frame is OK, the TBS Source One is slightly cheaper and you support the community not cloners, plus they sell parts like arms separately.
@cnc_dave kinked you some other frame choices too.
Always buy bigger rated ESC’s, it’s better to have more headroom.
If you buy a good All In One (AIO) flight controller then you don’t need a PDB. Get an F4 or better an F7 FC.
The receiver connections should be in the diagrams for the Flight Controller. I like the Matek FC’s as they have good documentation. Banggood sources generally don’t have links to wiring or manufacturers set up info.
Camera- Caddx Ratel is my favourite at the moment, amazing for under $30. It also has removable lenses and filters, plus is good in low light. PAL and NTSC are just formats for the image, most goggles do both, some cameras work best on PAL, some on NTSC. You can mess with that in their settings to suit you.
Cheaper motors are a bit meh. I like the T Motor LF40 as an entry level motor but they do cost more. If you buy better core components like FC, ESC etc then you can switch the motors later.
VTX is fine. Props would get you airborne and you will break plenty learning.
Thanks those of you who corrected my misinformation about the Spektrum receivers. I will not advise on those in future as I have only used two DSMX quad receivers!
