MBK 1-Skewer Sled
You might already have some of the simple tools and materials required. Anything you don't have is easily bought. If not exactly what I used, then at least something pretty similar!
These instructions on how to make a Sled kite might look a bit long, but each step is quite simple to do. Just steadily work your way through from top to bottom, skimming over any detail that you don't need.
At 29cm (11 1/2") tall, the MBK 1-Skewer Sled Kite is a rather small Sled, with 2 simple ribbon tails for extra stability.
This kite can stay up in fairly light winds but prefers it gusting into the moderate range.
I've had at least a couple of visitors report back favorably on the mass-production of these with a group of kids! Not to mention the flying.
