Ginga kites. A series of single line freestylers. Steerable as fighter, but gliding and unstable for tricks.
The small one
Ginga Fighter, all details are to see in another album
Various sizes and aspect ratios. From L to R: small; small stretched; std vented; standard; Large stretched.
All sizes: Fighter, Small, Small Stretched, Standard, Large
All types: Fighter, S, Small Stretched UL, Smal Stretched, Std, Std Vented, Large Icarex, Large chikara
Plan and building instructions can be downloaded from: http://www.windsweptkites.com/ginga.html
Small stretched, icarex, 3mm spars; gentle no wind glider, freestyler
Central section of the bow is 4mm (for the std size) glass fiber. Here untensionned, passing mid-way between the nose and the central cross.
The spar is then pushed down into the central cross bringing a lot of tension to the sail and giving its 3D shape to the kite. This central cross if from Eolo Gaila, and has a grove ideal for snapping the spar in it. However, any central cross trimmed to shape will work, or anything looking like a hook will be OK too. See alternatives on pictures of other Gingas.
Tail tensionner. The trailing edge is hemmed with a 25mm strip, folded in 4 (through a hemming device). The templates does not include a hemming margin, the hemming strip is added to the trailing edge.
Leading edge spar pockets are made of 2 inches strips, folded in 2.
Mylar on the leading edge, that is strongly tensionned.
Cut the leading and trailing edge, dot weld the central curve along the template, leaving 1/2cm excess fabric.
Sew along the central curve, dot welded
Trim the excess fabric, open and sew flat
Both wings are now assembled
Due to the central curve, the sail is no longer flat
In order to lay the central spar pocket, the curved sail must be tensionned "flat" on a curved surface
Place the central spar pocket flat (with pieces of sticky tape) on the flattened sail on the curved batten.
Large stretched, icarex.
Large stretched, icarex, made in Belgium
Tail tensionner, slightly modified to better keep the central spar in place; no more central spar pocket, just a few loops.
Nose reinforced with adhesive mylar (and sewn)
Battens are simply glued (contact glue), hand stitched at both ends (locked with a drop of cyanoacrylate glue).
Small, stretched, Ultra Light and flatter. Meaning fitted with 2mm carbon fiber rods (no central glass fiber section) and less central curve than initially. The trailing edge is visibly less tensionned, but does not harm for very light winds flying.
The aim is to make it less sensitive to pull-release for zero-wind/indoor flight. With the initial 2cm central curve, when pulled-released, the kite has a tendecy to make a vertical loop. The curve is usefull to stabilize with some wind but is not ideal for zero wind. With only 1.2cm central curve, the kite is stable enough for zero-light winds flights.
The original one (white) has a 2cm central curvature, the grey has only 1.2cm, and is effectivelly flatter. Keeping 2/3rd of the initial curve works fine. Why not to try on the larger sizes? Who volunteers?
Small Stretched UL, 2mm carbon frame
Home made central spar fitting: 4mm carbon spar glued with epoxy cement and sawed open. Works fine.
Ginga, Small one, on holidays in Corsica. Fits in any suitcase, a must have on travel.
