The idea is that the gizmo will return a plane to straight and level flight if something goes wrong and you let go of the sticks. Trouble is, in a panic situation, most new flyers tend to "freeze up with a death grip on the sticks" which means the gizmo won't help you much. BTW, A good trainer will self level by itself if you let go of the sticks anyway. Also the "gizmo" has to be programmed properly before each flight or it will "fight you" for the controls. Seen it happen causing a crash, and that was with a good instructor trying to teach. My opinion, not worth it!! Save your money for other stuff! [>:]
