This radio-controlled airplane/kite that runs 10 to 15 minutes on a rechargeable battery with a four-function controller has 14 LED lights for night soaring and receives the birthday-boy seal of approval. HuaiXing is known for its lightweight, cutting-edge RC aircraft, and the Air Kite is no exception. Salesperson Darlene Serville at the Memphis, Tenn., Toys “R” Us thinks this would be a big seller: “We have a lot of guys who like the radio-controlled airplanes, but sometimes they’re too complicated for the kids.”
