A simplified model for that purpose was in the works (which also extended the drouge automatically)....but was lost in my ransomware disaster. Bummer. Maybe I'll work on it when I have more time. Should not take that long to make.
As for the current model, if I recall correctly, I should have set it up so that it could be used as tanker in multiplayer in Tacpack - meaning one player has to fly it (but I haven't tried it...nor anybody I know of).
