I would certanly listen to the instructors in your club. I do know that there is a mustang on the market that is being advertised as a trainer, but I have no knowledge if in fact it can be a trainer or how it fly's. Speaking from experiance as an instructor, you want a plane that is slow and forgiving. If you want to build a plane from a kit look at a Sig LT 40 or a Great Planes Trainer 40. If you are looking at an ARF, the Avistar40 would be a good choice. I am sure that other's will respond with other excellent trainers as well to add to your choices. You want to talk with the club trainers about radio types so that your radio is compatable with thier's for buddy boxing. Did your Hobby Shop have other options for you to chose from or was the Mustang all that he had? I have always told all my students that the first airplane is not going to look good before or after learning how to fly, but it is intended to teach you how to fly the good looking planes later on. Good Luck and keep us posted, Dave
