@Xurasc0 I am also new to fpv, but i understand how it works. there are 8 type of components in a fpv drone. Flight controller(fc), eletronic speed controller (esc), vtx(video transmitter), reciever, motors, camera(analog or hd) and frame. if you want to build a tiny whoop( 65mm to 75mm frames) it is best to use a AIO(all in one) fc board. it is esc, fc ,receiver, vtx and osd all cramped together in one board so it is lightweight. osd is important so that you can see your battery level, far away from home point and other things. If you want to find an FC AIO board, here are a few examples : BetaFPV G473 5A AIO. if you want to use HD system , you can use BetaFPV Matrix 1s 3in1 or 4in1. 4in1 comes with a receiver if im correct. for cameras, Caddx ant 16:9 is one of the cheapest recommended-good-quality analog camera. If you want to go slightly better, you can use the Caddx Ratel 2. For HD system, you can use HD Zero , Dji 03,04,lite unit or maybe caddx walksnail. I hoped that my explaining help you! if you want more recommendations for hd f4's or aio fc analog, you can search for "HD system aio fc" and " aio fc 5in1 or 4in1 ". :D
