It was only slightly harder than the previous version, I had to have the shuttle fly up between the star destroyer and the lancer followed by my zig-zagging ace.

First thing you should do as soon as you get either ship is assign them hotkeys (after you start the shuttle moving so it gets started quicker) so it's easier to switch controls between them constantly and have ace zig zag behind the shuttle a bit behind (length of a battleship i'd say) and remember the escape timer starts when the shuttle appears.
