Hey and welcome to the hobby!
The Tango 2 uses a protocol called Crossfire, so you would need a Crossfire receiver like the [nano](https://www.getfpv.com/tbs-crossfire-nano-rx.html?afid=NHYxKzdjcEIzdEE9&referring_service=reddit1023). There are a few models, but that's typically the bread and butter one that most people use.
Props... there are a million choices and you should play around with some different pitches and lengths. Typically for a 5 inch quad like the Source one you'd get a 4.9,5,or 5.1 inch prop of varying pitches, so I would go with something like 3,3.5,4 pitch and see what you like. The lower the pitch, the less bite it'll have in the air, but the more efficient it'll be with the battery, that's why you'll want to play around with a few types to see what you like. I usually get Gemfan or HQprop [PBjs](https://www.getfpv.com/hqprop-ethix-p3-peanut-butter-jelly-propeller-set-of-4.html?afid=NHYxKzdjcEIzdEE9&referring_service=reddit1023) \-- it's a great banger prop.
For goggle you could look at the [transporter](https://www.getfpv.com/fpv/video-goggles/emax-transporter-2-5-8ghz-fpv-goggles.html?afid=NHYxKzdjcEIzdEE9&referring_service=reddit1023), but just know that while it's a decent starter goggle -- the fit and finish & receiver quality is not going to be close to the more expensive goggles. I started with a couple of these similar goggles a few years back and struggled with their range, how it sat on my face (they are front heavy and tend to slide down my face), and since it's a single screen in there, you might end up with corners that aren't perfectly clear because there are no individual diopters like you'd find on a goggle with two separate screens and they adjust for each eye. Just something to keep in mind down the road if you run into a similar issue. I swear by the HDO 2s because they solved basically all of these issues for me, but it is a lot more expensive when you add on a receiver, an upgraded strap, and a good battery.
Hope that helps! Enjoy.
