first you shouldn't be going for shots outside of the 450 range even with that sweet old 38

You can score hits but you need a pretty good sustained burst to do some real damage out at 800.
Turners ...other than the spits, 109s are good, the 205s are good, and the NIK can be pretty nasty, and don't forget the blue planes f4u, f4f/fm2, and the f6 all good turners. The F4u and the 109 make good E planes as well.
Try them all, thats where the fun is. Balistics of the different guns sets can cause a problem so you might look into some info on those so that you can set your convergence and know at what range you want to be shooting at.
Good luck, and don't be afraid to hook up with a trainer to help you knock all ( 10 years worth

) of rust off. They can be a big help getting it all back together for you. <S>
