I’d agree with @MagicQuasar1176 's statement. Depending on the age of your son, and his experience with flightsims, you might want to consider just buying a joystick for now. Most come with a throttle lever of some sort. Controlling an airplane realistically (i.e. with no in-game “helpers”) with yoke & rudders takes time, and for young children can lead to frequent crashes & frustration, resulting in them abandoning the game as too difficult to play. If your son is new to flightsimming, I’d suggest an inexpensive joystick with throttle & twist-rudder control (maybe a good xmas gift from an aunt or uncle?). If he is still flying by the time his next birthday arrives, a yoke & rudder combo would make a great gift…
Hope this helps,
Jon
