This has been a good performing aircraft with little problems so:
A week ago I downloaded the latest upgrade. After this the Longitude seemed to fly ok. A few days later the sim would not startup (hung up on startup screen). The last time this happened a Windows 10 upgrade fixed the hang. This time Windows 10 showed that a Saitek driver may be causing the issue, even though the sim had been running fine! So I elected to upgrade the Saitek driver? The flight sim started up with no problem. Why it took a week to decide not to startup is beyond me. Any way, the Longitude seemed to perform well until the aircraft hits the apron on landing. Breaking causes the aircraft to loose control and eventually crash. Keep in mind the landings have been smooth with no issues at all. I Am guessing the Saitek Driver upgrade changed something, but what?
Any help appreciated!
