I have learned to use expo on my elevator and i use 35% what a difference in landing, no more up and down it just comes in so nice and i get to use my stick a little without being touchy, i use it on all of my planes even my lt-25 i was doing touch and goes the other day on a grass field while others were wondering how i set it down so easy every time, a little expo goes a long way, it has sure helped me to improve my landings, i have been flying for several years and i have made every mistake a beginner makes and it seems that every time i go to the field i am still learning something new and since i have been comming to rc universe i have learned even so much more from the pilots that have alot of experience, listen to them and learn, rollie
