Beginner question

I've recorded a short flight:

This time at the take-off I didn't have to countersteer much, but when I was in the air and I relessed my stick at around 1:40 my the plane started to steer right.

By the way, I have torque and wind off, when turned on it's much more severe. So it seems turning those options off doesn't really turn it off, it's just reduces the effects (wich is all ok to me, I just want to learn how to counter this )
