Yes I know alt and speed are the best defense, but tooling around in offline mode, I discovered that once you are at a good speed (~300+) in formation, you can pull a full turn, and turn full around and even get on your own drone's 6 o'clock position through turning, and not lose the drones. Basically, it's a HIGHLY manuverable formation and if you do encounter someone who set up a perfect intercept run, this is probably your best bet.
Also, tried some other things as well that worked.
P.S. I tested everything with 50% fuel and full 5000 lb load out at ~7.5k
