I already searched it and I looked in the Mygeeto campaign lua, but I didn't find anything.

I want to include flying Gunships in my map, like this

those are animated look at the animation guide in the docs and also everything you need to know thread. If you want them to be flyable just add them like you would add vehicles

There's also a version made for Kamino called uta_fly_ride_gunship that is self piloted. To make it any sort of smart you'd need to build flyer splines, but it's much better than just using ZeroEdit's animations. In fact what you see in that screenshot is uta_fly_ride_gunship being used.
