I did a search on this and all I found was to use ACE to take winglets off a particular model, but it does not work for me. I know there is a way to change the aircraft config file in CS 757-200, but not sure how. I want to get rid of the winglets on the UA 757. I have downloaded and installed ACE 1.4, but the program says it is 1.3, don't know if that is OK. I have the pro pack version.
Thanks,
Larry
