NOTE 1: I've changed the measurement for the ties to 5 cm: this includes a 0.5 cm seam allowance. When sewn the ties should have a lenght of 4.5 cm!

NOTE 2: March 16 - Changed the B4 B5 and B6 lengths in the table (-1, -5 and -6 cm resp.) to get better speed and easier adjustment.

NOTE 3: May 24-changed the bridle lengths.

NOTE 4: July 1-Corrected an error in the way the A1 loop was attached, and adapted the calculator program accordingly. (the A1 bridle is now 2 cm shorter and the loop sticks out 2 cm (this corrects errors that would occur when you made the kite bigger or smaller)

After building a lot of them, the order in which I sew them has changed. Now I do it in the following order:

1- seam with loops on the leading edges, and seams on the trailing edges of the wingsection.
2- join the upper and lower wingsections: make sure you leave enough ribbon at the tip to make the loop.
3- join the panels in the center, only fold the bottom seam of the 12 cm panel: later on the ties are sewn in the seam.
4- mark the 4 delta's of the center panel, sew them, and sew the center leading edge seam with the ties. (this is the "hardest" part of the kite)
5- join the wingsections and centerpanel (seams with loops). Make sure there's enough ribbon left for the loops at the bottom and the 5 cm tie on the top corners.
6- sew the delta's in the top corners of the wing (centered between top corner and B1).
7- sew the ties in the seam that's still open.

This is the easiest way because you keep the kite as flat as possible while sewing.

All mesurements were chosen to use the ripstop in the most economical way. If you use the 1 meter wide cloth you can cut out the panels in the way pictured below. There are almost no leftovers, apart from the yellow section, and that's just enough to make the kitebag.
