KC set your trim to between 2.5 to 5 degrees nose up or middle of the green range for TKOF.

Oh and just a thought you did'nt have the autopilot on with the elevator control only selected on by any chance when this happened? just a thought as that would do it also or lock your elevator.

Other than that it should fly! (with flaps).

AS a good habit and it is done in all real aeroplanes, is that you should before flight do a control check, left right back forward and together to make sure controls are free and moving correctly, you can see the control yoke responding accordingly and some models control instruments indicating their position and you could confirm with an outside view as well.
