After I re-start the engines of my Perfect Flight L10-11 ( after using AES for example ) the right engine has little power which means the aircraft goes in circles when I increase power to move the aircraft.As I am still learning has anyone the answer to my problem so that I can taxi in a straight line.

I don't have this bird but just maybe able to help because I've had this issue a few times early in my simming days. Are you loading it with engines running or cold and dark? If so it may be that one of the engines may not be started if you have had another payware aircraft loaded directly before it. And is it just low power or no power? You may have to synch the engines I can't quite remember the procedure but if you search the forum here you'll get it. You press E + 1 2 3 or something like it. Sounds like one of your engines is only at idle power.Hope this helpsGeorge

Thanks for your reply George, I think that I have found the answer.I have AES installed, when I re-tested the engines I waited until the jetways are completly detached from the aircraft before stating the engines.All the engines started up normally.Maybe a small compatibility issue.I shall keep your advice in mind if I encounter the engine problem at other times with or without AES.
