What program are you using?
Unless you have counter-rotating props, you don't want to mirror the props..
Just make a copy (clone) of the part and translate the copy to the negative x coordinate (you show a right-side prop, which is the positive x coordinate).
In FSDS - CTRL-C, CTRL-V, F2 (and make the x coordinate negative)
In gmax - -
Edit->Clone
go to move mode
press F-12
insert a minus sign on the x coordinate,
