Flight Test Lab: Helicopters Paperback – Box set, February 24, 2004

I was disappointed with this purchase. It turned out to be a manually operated helicopter that did not work. It operated by a rubberband that twines in the middle which never can twist tight enough to the degree that it will lift the toy enjoyably into the air.And the helicopter snaps together with various pieces which did not connect tight enough to stay together.I wanted my money back as soon as it arrived.
