I used to have my students build the SuperSportster for there first kit and second or third plane but the last few years I have changed over to the 4*60. The 4* is a little easier plane to build but my real reason was it was a little easier for them to fly as a second plane after the trainer. Because of the sheeting used in the SS I think that would be a good starting point. Just a bit harder then the 4* but a better learning tool. For an advanced pilot it is a bit better flyer and not such a floater like the 4*s, something you could enjoy flying after you finish it.
