Gravity Trigger - 2012/07
A system that keeps an aircraft stable in even the strongest winds appears to be making a comeback.
The Gravity Trigger was conceived in 1989, and uses gravity, inertia, leverage, friction, tension,
and centrifugal force to control the decalage of a tip-launched glider [TLG].
Zenith
IF YOU'RE READY to go on a roll in Hand-Launched Glider-if you think you can take winning contest after contest-this model is a sure bet. Zenith has proven itself over and over in serious competition. Renowned F1A flier Bob Isaacson called it the best he's seen-and anyone as accomplished as bob in Hand-Launched Glider (HLG) should know. I built Zenith in February 1989, and immediately afterward the model won its first competition at the Max Men Annual. Win followed win: first place at the 1989 Nationals, first and second places at the 1990 USFFC, first and fourth places at the 1991 USFFC, plus multiple wins at annual meets and local events sponsored by southern California clubs.
Slow Poker
No stranger to making waves in IHLG, our author has another winner with this high-tech, 24 1/2-in.-wingspan, 6.2-gm national Indoor Category I Open record holder. Few aspects of Free Flight are more beautiful than the sight of an Indoor Hand-Launched Glider (IHLG) gracefully, smoothly, and ever so slowly descending from a 26-foot ceiling for a full 47 seconds. Three-quarters of a second can stretch to an eternity of pleasure when you're watching a glider circle lazily overhead. Slow Poker, the latest in a series of high-tech IHLGs begun several years ago, has dominated the field since 1986. The model not only delivers 47-second flights on a regular basis but holds the current national Indoor Category I Open record of 94.8 seconds for two flights.
