- Luffing in gusty wind is the worst thing that can happen to an inflatable and foil (foil has slightly more tendency to luff than inflatable and inflatable hasMessage 1 of 2 , Aug 1, 2001View SourceLuffing in gusty wind is the worst thing that can happen to an
inflatable and foil (foil has slightly more tendency to luff than
inflatable and inflatable has the worst reaction to luffing - simply
collapse and fall).
Until today, I thought the Arc was the only unluffable kite.
I converted my Concept Air 6.0 foil (opened cell) today for use with a
bar (2 front lines at the end and 1 center line to both back lines). To
make the kite turn faster, I modified the bridle by adding a new bridle
line (power steering line) attaching the front line to a group of the
back lines near the tip.
To my surprise, by tuning this "power steering line" properly, I can
make the foil "unluffable". The foil was frequently flying at a
"negative" angle (over 90 degrees) over my head.
This "power steering line" is acting just like an automatic brake line
that brake the foil just before it overly too much to collapse.
The only way I could luff the foil was to quickly overfly it and run
EXTREMELY fast forward (to put the kite even at a more negative angle).
By running forward without overflying the foil, it simply drifts
P.S., You can also make a foil somewhat unluffable by using handles and
keep good tension on the brake line; however, a strong gust could
overfly the kite so bad that by the time you apply proper brake tension,
the kite has way over flown and will luff.

toy - JOJO RAGE 12.0 m2 (projected area).
He is 170lbs riding with 6'6" x 18 1/2" Roberts directional board & flying
30m lines. We were measuring wind speed with both Flytec and Dwyer
windmeters - Luk was powered up, going upwind at 7 mph !! He was able to
stick some back flips (not too high - around 8-12' max) well bellow 10 mph.
With de-power applied he was riding on till wind reached 16 mph, then went
out with his 171 Liquid Force wakeboard and did some bigger jumps .. untill
he broke his 3 weeks old Slingshot carbon bar !!! (btw - great service from
Sligshot - bar was replaced right away under their warranty!!) ...
Rage 12.0 is easy to loop, no overshooting, re-launched every time during 3
days of testing.
Excellent kite for light wind conditions - it weights only 5.9 lb, god power
output, smooth pull and great speed for given size and conditions.
JOJO RAGE 12.0 is now available through JOJO dealers, comes as a complete
package (kite, bar, 4-line set-up with depower loop and safety leash)or as
kite only (kite, manual and bag).
