Have tried 2 test flights, the first one was full FMS and the second onewas hand flown, only used to FMC for V speedsFirst takeoff at Vr the a/c pitched uncontrollably to 40* and the recovery was after a series of wild gyrations. On the second takeoff it lifted off at 116kts, and a series of wild pitch gyrations. First landing (attempt) was auto land: the throttles did not retard as they should have and there was no flare. A/C slammed into the runway and rolled over. Second landing was hand flown and I had to force it the last 50 feet to the runway and it finally slammed into the runway and rolled over. I have a number of other freewares, including the Tinmouse 732 and the Frolov Dash 8, Fokker Priject, and never had a problem with any of them. Any ideas?thanks,db.

Long shot... trim?

Unfortunately, no. Probably a corrupted file.db.
