Of our 3 models of Flying Heli-Balls, the HY828 features a green/red textured ball with colored lights. The ball contains a sensor at the bottom which causes it to rise when it sense your hand about 6-7inches underneath. There is no real method of steering the ball as it flies. It only knows up and down, but the fun is it keeping it aloft for as long as you can! Angling your hand underneath could influence the direction of the ball's flight but there is no guarantee. To get it back down, quickly reach out and grab the Heli-Ball. Then proceed to turn it off the power switch. Crashing or hitting anything during flight caused the Heli-Ball to immediately stop spinning, preventing any further damage. To reset, Just turn it off and back on again.
