After I read your post about locking the ailerons I had a chance to fly an LT 40 and I played around with just using the rudder. What a DOG, it doesn't like just rudder and elevator. Your choice but I think you are going to be SORRY if you TRY to go that route. Besides, you will want a full house set up later so why not learn on one ??? Very few people fly 3 channel any more and most instructors feel it's better to start with ailerons then if you want, try 3 channel. ENJOY !!! RED
