few people truely MASTER the trainer. but i for one can crash a trainer with a great deal of expertise

not all trainers are equal i like my LT 40 but it has only 1/2 the usual dihedral and a slight increase in rudder surface area so it is semi areobatic also a tail dragger . OS 46. inverted is pretty good as i can fly it around the field and stay inverted. my students like it fine
i often train them on it if theirs has problems or not completed yet or whatever.

try some one wheel touch and goes with a target of where to touch down and see how you do. and see if you can do some stunts consistently..... but there is nuttin wrong with having a new plane also!!
