I'm new to this forum, so I could hardly answer before. For what it counts, sorry for the lateness.
Under FS you can make EVERYTHING fly. Flying couches, literally, for the lazy sim-flyer, Star Wars flying cars, Anime robots and starships of every kind, and even Santa's sleighs for the Christmas flights...
The secret, for those who may not know, lies under the fact that the shape of the 3D object depicted in the .MOD file does not reflect in any way on the flying dynamics specified in the .AIR and Aircraft.cfg files, so if you find a Delorean .MOD file (
that seems to not exist on any FS sites, though), or can make one yourself, it's quite simple to adapt the flying dynamics from a whatever plane to suit your Delorean, or helicopter FD if you REALLY need VTOL and are ready to sacrifice speed for it (
messing around with payware FD of a actually working simulated Harrier or F35 is QUITE more difficult than normal and simpler FD).
The only problems you could run into, adapting FD from a previous plane/car to another would be with the contact points, but if you're capable to make a model yourself (
that seems the only way you'll be able to have your flying Delorean at the moment) that should not really an issue.
