Range depends a lot on terrain and the receiver/aerial combo you have going. 2.4ghz waves don’t travel super far, their short wavelength limits the maximum range, that’s why things like the TBS crossfire use lower frequencies at higher power output, which can require a ham licence to operate.
Also you shouldn’t be flying outside of visual range, in many countries that is illegal.
I have been testing my 2 T8SG v2+s at 150 uW (highest setting I can get it to go to). In a crowded neighborhood with houses cars, plenty of wi-fi in each, I get about 850 feet line of sight before the controls begin to stutter a little. That's definitely where my FT models are getting hard to see anyway.
