Here it is... the kite for every one who thinks building your own is difficult. As you can see it isn't; as long as you scale it right other dimentions are possible, and it's an ideal kite to stack.
Because it has no bridle you can easily stack them on one line. The only thing to consider if you do that is to use a braided line instead of a cheap twisted one cause the latter will untwist under tension and mess up the stack.

The best choice for the tape is glass fiber reinforced 3M tape.
The frame can be made out of bamboo, dowel or glass fiber . I even made them using the spines of an old umbrella....

With kind regards to Dr. Deleto who tried to convince me he wasn't able to make a kite
that could REALLY fly.
