Can't get my mind off the 717 for the simulator...did I little bit of scavenging and most of the IXEG and X-Aviation developers on this website forum are not really online, if you visit the X-Aviation site you can see a lot of general aviation planes that are out with 1 newly released plane, I haven't heard of any of the other planes that they have released other than the MU-2 and the Classic 737 but I might just not be caught up with everything or if they might've been released before their 737, maybe their focus is on general aviation instead
There are other people trying to get this plane for x-plane like the Freeware 717 but that is about 6 years old now, the updates look pretty good and there were a lot of good pictures coming out of that but the modeling delivery has been going on for about 3 years now...not sure if the person is still working on it since we haven't had an update from them since 2022ish?
Otherwise we are thankful that there are efforts to put a proper 717 for the flight sim like the TFDI one, we aren't the ones developing it after all, we're just waiting..
