It should recognize the second yoke, similar to how it does with two of the same throttle quads or having a yoke and joystick with same axis/functions.
I use both of these examples, no issues.
Whichever one is physically moved first, will be in use. As soon as the second one is moved, it will be in use.
Because both are mapped the same, with same functions set, I’m guessing you’ll set up like that, be sure there is sufficient dead zones so that no input noise is being generated, by either yoke.
Also, even if you use a button, switch, etc, on the yoke not in use, that one will become the in use yoke. Hands off the not in use.
Neat idea!
