Ready to fly out of the box, this fully-assembled remote-control helicopter allows beginners to test their flying skills indoors in large, open areas, and at heights up to 100' outdoors. Equipped with operating navigational lights for nighttime flights, the toy helicopter has a counter-balanced rotational drive that keeps the dual coaxial rotors counter-synchronized for stability. The dual-frequency transmitter controls vertical movement up to a range of 200' for four minutes before requiring a recharge on the included recharge pad, which revitalizes the built-in battery in five minutes. Six sets of decals are included for customizing the look of the helicopter. Requires eight C and two 9-volt batteries. Specify Blue frequency or Orange. Ages 8 and up. The manufacturer has confirmed that this item meets U.S. Federal toy safety standards for lead. 8 1/2" H x 2 1/4" W x 15" L. (5 1/2 oz.)
