Background: I am a complete beginner on Flight Simulator X: Steam edition, using a simulator setup with rudder pedals with realism set to the max (to simulate more realistic flying).

I understand that rudder use is essential to align the aircraft to the runway centreline during takeoff due to the left turning tendencies. However, I cannot seem to consistently align the aircraft to the runway centreline during takeoff. Sometimes, I just run parallel to the centreline.

Questions:
1. Is this common in real life flying? Are actual pilots consistently able to align the nose wheel to the runway centreline during takeoff in such single engine propeller plane or am I being too idealistic?

2. How is the operation of rudders in an actual aircraft like? Slow smooth gentle depression e.g. to the right pedal each time the aircraft swerve to the left or are the left and right legs constantly moving in quick succession to keep the aircraft aligned to the runway centreline?

3. Generally, how much of a push is required on the pedals during takeoff? It seems to be very very slight 1cm touches to my rudder pedal on the simulator. Is that realistic?

Thanks so much everyone! All answers are appreciated!
