Sometimes when I launch my Glo-Copter it goes straight up and comes straight down. Why?
When the Glo-Copter is not launched high enough it will go straight up, and down. To keep this from occurring you should increase your angle of launch, and add more stretch to the rubber band. For best flight results be sure to launch your Glo-Copter as high as you can. Because the higher you launch the Glo-Copter the longer it will stay up in its lofty domains. Note: When your Glo-Copter flies straight up and down do not try to catch it. Not until you are good at catching the Glo-Copter toy.
