All the models mention are excellent trainers and will give you the best opportunity to learn to fly Radio Controlled aircraft. Now all that is left is to decide what to get for the bucks. Tower offers several excellent packages for anyone wishing to get into the hobby. I personally Avistar and with the combo package feel that it offers the best bang for your bucks. It does have a simi-symetrical wing that will allow you to explore aerobatics yet will land comfortably allowing you to learn the techniques with out causing undue stress.

Be sure to contact an instructor that will give you the most training possible.
