I am trying to set up the throttles to use with both engines. I know I have to do it though FSUIPC but I can't get it figured out. I don't understand the instructions from their web site.

I'm not sure I really know what you're asking, but you don't have to use FSUIPC to get it to work with all engines.If you want the one throttle to control all engines, set it to "Throttle Axis."http://ftp.avsim.com/dcforum/User_files/3e2c53002b8db6cb.jpgIf you want to setup the throttle, mixture, and prop levers to control different engines, just set them here:http://ftp.avsim.com/dcforum/User_files/3e2c53242ca5593c.jpg
