MBK 1-Skewer Box
If not exactly what I used, then at least something pretty similar!
The instructions on how to make a box kite might look quite long, but each step is simple to do. Just quickly work your way through, skimming over any detail that you don't need. All in all, it should be quite hard to make a mistake!
The MBK 1-Skewer Box kite is rather small at just 29 cm (11 1/2 in.) long, with cell panels measuring 14.5 cm x 8.7 cm (5 3/4 in. x 3 1/2 in.). It will stay airborne in moderate winds, but does even better in fresh winds.
Larger box kites don't need a tail, but my original 1-Skewer version was much happier in the air with a decent length of light plastic attached to the lower corner. If there were such a thing as 2 mm diameter bamboo skewers, the little box could probably go tailless!
Like all the other MBK 1-Skewer kites, this design can't be taken apart for transport. However, that's not much of a problem due to its small size! Just be sure to treat it with care when handling or transporting it.
The video up there shows an extra tail in action, trimming the kite straight. You will need to experiment a little, since adding too much side-tail will make the kite loop around in the opposite direction.
