Well it can be done if you are willing to take the risk of dropping out of Zoom. I've gotten fliers on my tail before where I dropped to Hover so I could turn 180 and Vector Strike back over the guy (although often when they are on your tail you are already dead). It is better to have a fighting chance than none at all. If you go a 2nd Turn with a Flier on your tail you are largely dead. Your only options are to:
1. Go Fast and get off the board to come back in Ongoing Reserves with your tail shaken.
2. Drop to Hover (if you have the rule) and spin around to Vector Strike with the Helldrake.
You also get to spin around in Hover too so you will now be on "their" tail. You can be shot at by everything on the board though now and they won't need 6's to hit you.
