Mike, Stunt kites aren't "off topic". They are a fantastic way for fliers to get over "figure 9's" and for retreads to get their coordination back. Search "stunt kites" on this forum and you will find quite a bit of info. I was helped a lot by info from Tony G., Howard Rush and others.
The essentials are:
1- Wind source within the wind envelope of the kite you buy.
2- Have a flying site at least 500' downwind of a tree line or other obstruction.
3- Fashion a flying handle from a 14"+/- broom handle with holes drilled from 7 to 10" wide to attach the kite's flying lines. Remove the single hand handles and attach the lines directly to the broom handle.
When I returned to flying after 35 years off, I was having trouble regaining my coordination and the ability to fly inverted and outsides. The stunt kite cured that the first time I flew it. The kite has the ability to perform inside and outside loops, horizontal vertical and overhead eights. The overhead will be about 75-80 degrees instead of completely overhead. You can even do the entrance and exit of a wingover.
I live on the north shore of the Barnett Reservoir and a boat ramp 1/2 mile from my house has three miles of unobstructed wind blowing off the lake. Whenever I cross the causeway across the lake and there is a "chop" in the water, I get home and get out the kite and go fly. Lake P. might be a good place for you to fly.
I got my kites from Midwest Kites.
http://www.midwestkites.com/dual-line-kites/ It is a husband and wife business and they have also flown c/l. You can call them and they will take time to answer your questions. I first bought a "Ticket" kite (french) with a wind envelope of 5 to 20 mph. Then I bought a Prism 4-D ultra light for the days when there is not much wind. You can also buy a 100' tail to slow down the kite in winds over 15 mph.
Good luck!
