MBK 2-Skewer Sled
You can expect this design to fly higher than most cheap store-bought sleds, particularly in very light winds. And being a simple sticked design, the smoother the breeze, the better.
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!
At 58 cm (23 in.) long when rolled up, the MBK 2-Skewer Sled is small enough for kids and yet provides great flying performance for adults to enjoy as well.
This sled has a shallow V-shape cutout at the top and has spars which are a little further apart at the top than they are at the bottom.
No tails are required, although long and colorful ones can be used for more spectacle in the air!
