adjustment bead alternative
if yer’ like me, sometimes you just got’s ’ta use a bead for the upper bridle adjust on your fighter kite. here is a hot idea for making your own!
“sculpey iii creative clay” ( not clay ) is a craft product made from pvc and a plasticizer. this soft material is sculpted to suit and cured with heat resulting in a hard, light, and durable mass.
although the finished pieces may be painted, they come out of the oven with a real nice texture to them like fine abrasive paper (that way the bridle won’t slip). cured pieces may also be drilled, carved or sanded. the gunk is sold in 1 oz. bars or kits, available in 12 colors and is reasonably priced. grab a slab and play around with it some.
available at art, craft, toy and hobby stores, or, write our friends at polyform – ‘the sculpey people!’

coriolis, moving, velocity, rotation, imparts an acceleration that is, perpendicular to the object's flight path. the result is a curved trajectory. the magnitude of the acceleration is proportional to the object's speed and varies with its latitude (from zero at the equator maximum at the poles (latitude: 45.5 degrees north or so slack float drifting a 10mph wind. 10mph coriolis acceleration is only one twenty one thousandandth the acceleration of gravity. rate of six thousandths of a degree per second. in an hour, flight by 21.5degrees. clockwise southern hemisphere, direction reversed.air at 10mph, miles coriolis acceleration.

aerodynamics is everything when it comes to making fighters spin.
