I've been going to build a Jordan Airform 400 for years now and finally finished one last week. Here is a picture of it on it's maiden flight:
Wind was very light all day and it flew great! Vital statistics:
18 x24 feet, 120 yards of fabric in the kite, 180 feet of bridle line, 25 bobbins of thread, most of the face of the kite was sewn together using strips of fabric left over from various projects finished over the past 8-10 years. I got to a piece 16.5 x 18 feet before I ran out of strips long enough to make a single pass. Flies in about 4 MPH wind with a 15 foot drouggue on it for a tail.
