The above is a link to the arcusers group at yahoo on the subject.
I have a little T-Arc and I really love it. It is the smallest size in my Arc quiver (1120 and 840 S-Arcs) I fly it on a 20" bar with four line set up and a sliding ring leash on one of the front lines, no bungee. On 100m lines it will ZING across the window in about two seconds and turn around and back in the same time. Zoom zoom zoom. It has your attention. It is a REALLY fast little kite.
My five year old flys it on his own and gets tugged around in light winds less than 10mph. He has yet to "crash" it but he was taught how to fly it by me. It's a cool thing to see such a little guy flying a foil. He likes it better than the B-2 he was taught on.
In wind, it will pull and pull hard. The thing about it is that it is so quick. I want to put a chicken loop on the thing and fool around with it. I think this one would be cool to use for being pulled around on a skateboard or if I was an ice skater on a frozen lake in wind, that would work too!
But for the most part, I just like to fly it around because I am astounded with the speed. It is so fast, really fast.
I've heard a lot of bad press about this little Arc and well, the more I read about it, the more I know that the people writing didn't set it up in four line mode. I have heard that it comes with two line instructions, if that is the case, throw the instructions away. In a pinch you can simply take the little T and put it on your regular Arc bar/line set and fly it in some wind. That's what I did until I could set it up with a light weight bar/line set.
I've got several hours of flying the T and I am here to tell you that it is a high performance Arc kite capable of entertaining just like it's bigger brothers.
