Jucava,
I'm concerned about one statement you made in your earlier post,
" ... I'm using the slip to reduce speed and to align the plane ..." Is your instructor teaching you how to reduce speed by entering a slip ?

A slip is where you use the fuselage as an air brake by turning the rudder in one direction and the ailerons in the opposite causing the place to enter a somewhat sideways position and the surface area of the fuse slows you down. Is this what you are learning ? I'd consider slipping an advanced techinique that I would not teach to somone just learning how to land. How are you doing with it ?
