Ok, I think you posted this in the wrong forum, but anyway (the "Hardware and Software" bit would probably have been better, but Skuzzy'll probably move it for you soon):
flight controls are sluggish. can not aim and hit target when flying level or going verticle.
If you mean your plane in Aces High isn't responding fast enough, try adjusting the scaling of your stick from inside Aces High. Also, if your nose is bouncing try the scaling.
plane on 6 not showing up when you use hat switch to rear view. ( you only see him when hes firing at you from the foreward view).
You need to shift your head position around to avoid this: hold down the button to look backwards, then use your arrow keys and page up/page down to move your head position (don't let go of the hat switch). When you've done this, press 'F10' to save that head position.
