Randy, if you want your aim to be good, you need to work on it. Aim is a very perishable skill and tends to be the first one to go after a Aces High vacation.
Work on the drones offline until you can 'one pass' them from any angle at any speed; those drones take more damage than planes normally can and keep flying. When you start putting the entire package of the 38 together, I'd recommend considering turning off tracers. Too many people aim with the tracers instead of gunsight, not to mention it gives the bandit warning and can even tell him which way to jink to avoid fire.
edit:
One more thing, gun accuracy can save your bacon and is arguably the most important skill in Aces High. For example, earlier this week I was flying along in a low speed climb and I didn't realize that my icons were off. I looked around briefly and saw an aircraft dropping down on my 6 o'clock. I sloppily broke hard into him and fortunately he missed, as I could now tell he was a 109K.
I waited for him to come back down and desperately tried to build up my energy reserves. He came down, dropped beneath me for a moment and I had less than a second for a snapshot. I got lucky and the rounds I fired entered the cockpit. If I missed, I would of been nose low against a 109K with alt and angles on me, aka 'deadmeat'.
