Making Sure

So, I am hoping I am getting this right and could use some technical verification help. Have had a DJI Mavic and Spark for some time now but it is time to get into freestyling, racing and the whoop thing.

Seeking some tech help in order to place an order correctly. Going to buy Flysky's Nirvana controller. It comes with two receiver boards (one small single and one larger dual antenna receiver). Would I be correct if I installed (connected via connector or solder) one of the receivers into the FC that comes with the drone? I think I am going to buy an Eachine Trashcan drone whoop to start with.

The Trashcan comes with a VTX which I will use a Fatshark (HDO FPV) to receive video. Will this VTX board transmit to and be received by these googles? Do I need a specific widget for the goggles?

Down the road I may explore a TBS Crossfire, it too comes with receiver board, this would replace the Flysky's board on the drone? Then on both the goggles and controller I would plug in the Crossfire modules?
 
I can't really speak to TBS crossfire gear but in general FPV is transmitted at 5.8GHz frequency with 25mW to 600mW transmission power (TBS unlocked I think allows 1W or maybe more). For the HDO goggles you just need a receiver module of some sort, personally use the laforge diversity modules but rapidfire is a bit easier to install without tearing the goggles apart which can be nerve racking but is doable. I ended up adding a 5V regulator to the goggles and replaced the momentary switch for the fan with a toggle switch that fit in there pretty well so now just one barrel jack connector powers the fan and goggles and can throw a big 2S in my pocket instead of on the noggin.

For receiver to FC that's roughly correct, just need to power/gnd the receiver and get signal from it into the FC which is usually one wire from receiver then need to configure FC. Main thing I look out for is F4 processor on FC and micro USB also ideally boot button instead of pins. Any brushless is pretty fun in my opinion, brushed are good for indoor flying mostly or zero wind.

Transmitter and receiver just need to speak the same protocol for them to work together. For FPV antenna common to use circular polarized antenna just need pair of rhcp or lhcp together don't mix between them (same on VTX and goggles receiver)
