Only used once. Bought brand new. Leopard 2 A6 MBT 1/16 R/C Full Pro Version, with the remote control and battery included. Shoots BB's and creates smoke effects. Tank has sound effects as well. I bought this thinking I would use it. I have only used it once in two months. Selling so it can go to someone who will use it more. Battery is a 7.4V/1800mAh Super Li-ion battery
