After I loaded the "must" have file...Nothing has worked rigtht...After firing up the engines and ready for takeoff...(Using single control) for dual throttle, it shows both throttles increasing on the pedestal,however, only the right engine increases power...The number one engine has no response...What am I doing wrong?

See if the url below helps. Sounds like your engines are unsynched. http://www.flightsim.com/vbfs/showthread.php?209891-Old-question-same-problem-throttle-sync
