I know about that freeware addon. Looks like EDAZ from the distance. If you´re look closer you will see lot of missing modeling an texturing skills. It looks far far away from the real one.
Unfortunately we´re discuss about the real one and passionated scenery development in this thread.
Because no data is available for these aircrafts especially the a350 hence, I see it's really a wise decision from Aerosoft to make the a330neo version. If you think about it, Would you do the a320neo or any aircraft belongs to a320 family? surely not because lots of these aircrafts had been made why do you want to make something that is already available and most people had flown them hundreds and thousands of times. In order to, sell your aircraft it should be something new or special like when you compare Fenix to Flybywire. The a330neo only has a one competitor which is the Headwind, and no guarantees that Headwind will do an amazing a330neo as expected by the simmers so why not for Aerosoft to compete Headwind on delivering better and more realistic a330neo? I don't why a bunch of people are against this project as it seems very promising and I'm very excited to it.
