Rokkaku

Sutton Flow Form Gone With The Wind
used by permission

The Rokkaku or Rok is an old Japanese design that makes for a great stable lifter. The Rokkaku is also a great kite for displaying creative graphics and artwork, because of its large expanse of uninterrupted sail. Large Roks require a moderate amount of setup, usually the center spar and two bow lines. If you want a shorter storage length the cross spars can be broken down also.

The Rok can be launched without assistance by releasing it from the hand, if the winds are strong, or by playing out a length of line and placing the kite face down with the top pointed toward you. You could not launch the kite by standing it on end because the kite would almost immediately roll until the top was pointed down.

USER COMMENTS:

David Hunt- A 7 foot tall Rok was the first large kite I ever flew. It was a very steady flier but needed a tail in higher winds.

Bill Gaston (June, 2004) - I have built ripstop nylon Rokkakus for maybe 15 years . I find they can be adjusted to be so stable - it looks like they are "nailed to the sky". I use a 6 ft tall standard Rokkaku in winds over 16 mph to lift my 2.25 lb camera pack. I like the 8 footer in winds between 8 and 16 mph.

Some experience in adjusting the two adjustable lines on the back and also the bridle will be learned in a few outings. One rule I have is to start with the upper tension line with less tension than the lower one. That means the upper cross spar will be more "straight". The lower spar is to be bent more than the upper one. A good stiff verticle spar that does not bend helps too. I have flown little Rokkakus of 2 ft. tall made of Tyvek and bamboo to heights of maybe 1000 ft on button thread. Maybe it got a thermal. HAVE PHUN!
