I really enjoy my XL, which I chose because I felt a larger model would be easier to see. A friend bought a used Nano last year and we got it going and it flies really well also and he is very happy with it. If you already have a Nano, I'd suggest that you go ahead and get it ready to fly as I'm sure it will serve you very well. Once you've got some experience, there are all kinds of possible choices for a second jet.
