Are you using the iFly 744? Maybe you have some ideas. Took 2 test flights and all seemed okay except for the T.O and landing. The first flight was full FMS, the second flight used FMC only for V speeds.
First takeoff at Vr the plane suddenly pitched uo to 40*. Managed to recover with extreme pitch fluctuations. Second takeoff, the a/c lifted off by itself at 116kts (!) Extreme pitch fluctuations followed.
First landing was full auto-land. The power levers did not retard at the necessary time and there was no flare. The a/c slammed into the ground and rolled over. Second landing, hand flown, a/c floated forever and when I forced it onto the ground at about 90 kts(!), again, the a/c slammed into the ground and rolled over.
Any ideas?
thanks,
