How can I get dual throttle control without going to the expense of buying a separate throttle unit?
If you can run to one of the CH Products three lever yokes, assign the first and second levers to right and left throttles and the third lever to control the props (it helps if you have FSUIPC installed, in which case you can map the axis of this lever to ‘four props’ which will keep everything in sync). Then go to the FS aircraft realism menu and check automixture, unless you plan to adjust this via the keyboard.
