Blacplasticno, it objectively isn't. You can grab an iRangeX for $80 and a Holybro Shuriken for $100, which will be less restrictive than any FlySky (seriously? FlySky?) radio and include a F3 flight controller and FrSky receiver with telemetry support (or Futaba, or DSMX, your choice since the TX you bought can use any of them). Sure, you'll still need batteries+charger, but it's worth investing in a decent charger over their no-name one, same with batteries. You shouldn't be using a 3S on any 5" drone.
Note how my setup didn't include a headset? Yeah, you'd have to buy that too if you joined this drop
