Basic, beginner suggestions for 3" build-

[Gunnet9]

Hi guys. Beginning my first build on a 3" Volador VX3 frame. Been flying for 8 months, still using FRSKY and analog video (will make jump to ELRS soon). Need suggestions on basic, 4S, ESC/FC stacks, AIO's or whatever to use. VTX also. Trying to use a decent VTX that'll use a decent antenna, as I have the room. All the electronics are still sort of confusing. I plan on using 1404 motors. This frame seems to roll with 20x20 mounting pattern. Don't need any components too crazy or expensive. Just a basic park flyer for now.....
