I updated the X-Wing with the config values from the CJ4 jet and it is faster than previous version. I've also included the jet engine sound. I can't work out how to take off with it properly so either spawn mid air or use slew mode (press 'Y', F4 to increase height, then 'Y' again)

You should remove the previous X-Wing if you have it installed as they can't co-exist. I've left the other X-Wing in there and renamed to "X-Wing-piston-nosound.zip" for those that prefer a slower flying option.

Extract to your "Community" folder but ensure it's as per folder structure shown.
