Of course, it is not out of question that the game simulates this correctly. What caused some problems was the take-off rotation. Since the main gears are well behind the center of gravity, the elevators do not have enough control authority. This was solved by adding extra pitch momentum during take-off. This is the case in real life too.
Additional momentum is gained by automatic rudder input.
When airborne, there is plenty of pitch control authority. Looses speed more rapidly, i.e., cannot hold the same airspeed during high alpha turns. Not very sure about how large the deceleration should be. Gears modelled more carefully. C-model has better acceleration and max speed.
