I DID IT!! I WON!Flew in a straight line away from them, then watched as they converged into a line and bumped each other to death.
I used the same method, except once all the drones were in a line, I would do a 45-degree turn, A-burn until they were in a line again, (while staying generally within 10 Kilometers) then repeat.
At a few points, the drones started to blow up in chain reactions, I saw about 10 go off at once.
After about 30:00 minuets of this, there were only 15 left, averaging around 30-17 health each, so I dogfighted (dogfought?) the rest and WON!
Wooooo!
