Basically, Ledpig, like others said, you've just got to go out there and take your lumps. Push yourself to get the most out of that plane you can. You're going to die trying this, more often then not, probably for your entire online career. But, you will get better, stay alive longer, take more of em down with you, and have more fun.
The only real chance you have, assuming you're on the deck and pilot skills are equal, is some sort of scissors combo to try and make him overshoot. But really, with the hispanos on that Spitty, and the huge target of the 38, it's going to take a TON of practice to be able to avoid his shots at each cross. And the 38 isn't exactly the best at scissors, either. There's alot going against you, really. But without practice, everything will be.
Basically to shake a guy on your six with a scissors (in any plane, really) you need to possess two things:
* Better instincts so you can dodge his shots; and
* Better control at looooooow speeds
But it'll take forever to develop these skills in the MA. Take Schatzi up on her offer and spend some time in the TA or DA instead.
