The 90Nothing was designed for indoor flying. It works and it is light enough for easy flying, but it is not very floaty. However, outdoors on 5-15 meter lines it is very nice (5 meter in almost no wind, 10-15 meter if there’s a breeze). You can fly in parcs, parking lots, campsites etc. It will give you almost all the tricks, especially when you add a few grams of weight in the tail (try up to 6grams).
Good luck building this fun little kite!

- Stitch the panels with a small zig-zag stitch.
- The centrecross is a 6mm endcap with a few holes for spine and spreader. Use a o-ring or cut off vinyl endcap to mark the position of the centercross on the LS.
- Same for standoffconnectors, I made them from 2mm and 3mm endcaps.
