While this is not a bug or a problem here is hopefully some useful feedback to improve the flight model.
The aircraft seems to have a little too much directional stability.
Behavior during the takeoff and landing phases seems fairly realistic, however not a lot of rudder input / correction is required during power/speed changes. High power, slow airspeed (during a climb) should require a boatload of right rudder. When reducing the power the nose should yaw left.
Similarly, any input of aileron (especially when you have 4 of them!), should require a fair amount of rudder to counteract
