The super sportster 60 is a great flying plane. However as you noted it is not generally considered a trainer. It is easy to fly and you shouldn't have much trouble flying it other than it is probably much faster than the trainer your used to. I estimate my SS60 with a ST75 out front to do around 70 mph. The area where I would see the most problem would be with landings. Landings are probably the most difficult area for beginners to learn anyways, and flying something like the the SS requires more throttle during landings than most trainers do. This just complicates the issue slightly.

Have fun.
