Jetb go offline get in your favorite ride climb to 2 or 3 K above the field. Now fly loops, immelmans, split S's, tight turns, inverted flight etc. All the while you are doing this, use your hatswitch to keep the tower (or hangar) in your view sight.
Once you are comfortable flying in different attitudes and keeping your target in sight, pick one of the drones and fly these manuevers around it, keeping him in view with your hatswitch. At the same time, keep tabs on the other drones, and know with some certainty where they are in relation to you and your target drone.
Then come back and we can talk about SA.
I can't remember the last time I killshootered myself, and have and do fly in some pretty busy furballs.
Bottom line is, if you are getting killshootered on almost a daily basis, you have a problem with SA, not killshooter.
BTW, that exercise I detailed above does help. Not trying to be antagonistic here, but am positive this is SA related. Target Lock is another Bear waiting to bite you in the butt.
