Pattern does become consuming! But you will love it.
A friend flew a Python a few years ago with a YS 1.40 FZ. From what I remember is performed well until a mid air at the end of the season. If memory serves the original was over 2m long so check your length. The stories I have heard Piorons(sp) work was very good when he finally delivered. Try Falcon hobbies I think they still sell some of his stuff. You may even find Henry's address on the NSRCA site.
