One of the weirdest flying contraptions we've ever seen. A four-engine, four-rotor flying widget. Each channel and motor on the craft is colour-coded so you can easily identify what makes it go where. Once you get the hang of it, you'll have hours of fun! It has a built-in rechargeable Li-ion battery that recharges from the remote unit. 20 minute charge gives about 5 minutes of flight time. Specifications: • Requires 6 x AA batteries • Size: 230(Dia)mm
