This is one of the most critical parts of flying, even for real aircraft. Other parts of flight (like take off and flying around) does not restrict you to a limited amount of space, whereas landings are typically done in a confined amount of space. So this calls for a great deal of practise and fine stick adjustments, to do it right.
To put it in perspective, if I were to practise flying on a sim, I would spend 15% of the time on take-offs, 30% of the time on flying around and the bulk (55%) on landings !
Just like take off, remember to land INTO the wind as much as possible. Plan ahead. Most people fly past one end of the runway, take a U turn, and come in to land. One important thing to note during such a landing attempt is that almost all the time, you have to lower the throttle to glide speed BEFORE starting that U turn. I have seen many newcomers make the U turn and then reduce the throttle, only to see them overshoot the runway.
