That dragon kite is really easy to build and fly. It's got a spar across the horizontal attached to a pocket on the ends. Easy , just cut out a similar shape and attach the rod. Micro carbon or bamboo or whatever you can think of. Wood dowel,coat hanger wire, etc. The shape can be concave or convex. I'm sure you know from Dreaded Geometry. Better than Calculas based Statistics. Beat of a course. If it doesn't fly concave switch it backwards. No real rules in kite making and designing, except HAVE FUN!
