Great replies and advice, everyone.
This is the fourth time I've tried the Dropship. Each time before, I purchased it because I loved the cockpit - especially in VR - and the weapons/loadout capability. But I always sold the ship soon thereafter because the drift bothered me during starport, outpost and planetary landings and the ship was slow as a turtle in 4/0/2 pip configuration during combat.
As far as combat, it sounds like I should think of the Dropship as a strafing ship rather than a turning ship. If so, that actually sounds like fun, so maybe I'll give it another try from a new perspective. Would lightweight mods help it strafe better?
