Terra,
Reversing at 1.5 aint enuf room to even get halfway reversed. Its enuf to get your bellybutton shot, espc if its a stang following you.
I would look at things to try and avoid having him there in the 1st place. If he's higher than you and on your 6 its only a matter of time until he's in gun range. Make him work for his kill, and hope that he slips up.
I'd wait till at least D3.0 untill i try and reverse.
If you cant get to that distance and he aint gaining then head for something friendly: fellow pilot, your wingman, ack (get called all sorts for this
) at this point your looking for anything to get him off ya 6.
Just remember to try scrub away at his E advantage and try your best to conserve what you have. Stay fast, and always know where help is.
There are alot of masters in the stang that may some other tricks in their books, but the odds are against ya in that situation.
Spat.
