I've trained a couple guys on the PTS, if your stuck on using it to train make sure your instructor is cool with it, you have an instructor right[>:] With it and be prepared to take twice as long to learn, learning on a tail dragger is not ideal. You have to learn to use the rudder and cross control from the start which is too much for some students.
cross control is using the ailerons and rudder opposite each other to maintain wings level and direction at the same time. You can also do it to induce a forward slip to loose altitude without gaining airspeed <-advanced maneuver, don't try until you know what you doing.
