or if its not the engine torque maybe its your joystick . go to external view an check if your left aerlion points up and your right aerlion points down than itsyour joy . i have a crappy joy so when i change planes i always have to configurate my joy with the buttons on it to let my plane go straight . maybe the same thing will happen to elevator if its pointed upwards

hope this helps
