i have a sig lt 40 trainer, and i have found that my faster landings are due to an approach angle that is too steep.  sometimes this is inevitable, due to a dead stick or just mis-calculating.  what i do if i am coming in too fast is wiggle the rudder stick side to side, this helps dump a lot of that speed by increasing drag, the tail of the plane goes side to side.  just be sure not to over do it, and get it straight before touch down.  you can also hold a little right or left rudder, and give a little opposite aileron to almost crab in, this method is mainly used for crosswind landings, but it will reduce speed as well.  </p>
