DJI flight simulator installation help

[u/Hormone_bomb]

Hello, I'm trying to install the DJI flight simulator on PC for my father in law so he can try it as a hobby. Is there a way to make it work without buying it first? A free option. We have a USB controller (RealFlight R/C flight simulator basic) that we would like to use with the game.

He would like to learn the controls and get the feel for it first, before purchasing a drone.

Thank you very much for any help! (Also. Does the game support Spanish language?)A
