You're going to need a car... You can either use a mod, or any of the original GTA cars, it doesn't really matter. What matters is that you assign "154" ID number to your new vehicle. That's pretty much it, as the game will take care of everything else
Just install it as you would install any other vehicle mod and don't forget to add COL model & data entries, if you're adding a new vehicle!
|150, ghost, ghost, boat, PREDATOR, GHOST, ignore, 1, 7, 0|
154, delorean, delorean, car, MRWONGS, DELOREA, ignore, 10, 7, 0, 89, 0.72
This particular vehicle will behave like an ordinary car at lower speed and will take off like Dodo at higher speed. HOWEVER, it's not being controlled like a Dodo plane which makes it much easier to navigate, even to land properly.
You can use this car to fly between the islands, or to reach remote, distant locations such as Miss Liberty, Lakeside Island, or any other map mod that you might be using.
Feel free to ask any questions & enjoy re-exploring Liberty City all over again
