Yes, but how many drones can you fit in an escort hull anyway.... Oh wait a minute, wrong thread.
This isn't a cheat at all.
Probably a waste of typeing to point out the obvious flaws in this strategy. Mines on the warp points will stop your stealth drone launchers before they can launch. Mines on the planets will stop the drones.
Even without mines, any defenses capable of stopping a standard ship attack will stop your drones as well. Point defense on sats or wepons platforms will be particularly effective.
