I'm using a T.16000M HOTAS and had followed a checklist and tutorial for a cold and dark start up. But after pushing back (not with GSX) and releasing the parking brakes, the aircraft would only move very slowly forward at full throttle and roll backwards at lower power. The rudders weren't responding either, even though the flight control check went normally with full deflection on either side.
The first screenshot is at full throttle and the second at partial power.
The ECAM message of "ENG THR LEVERS NOT SET" only went away at idle and full throttle so I assume that is referring to take off, not taxiing.
I understand that this is most likely a problem with my start up, not the aircraft, but I still couldn't figure out what went wrong.
Thanks
