The hand held transmitter has 2 control sticks that direct the blimp. The toy blimp requires a 3 volt lithium battery which will provide over an hour of flying time or longer, depending how fast you fly. The radio transmitter requires a 9v transister battery which will provide many hours of fun. Both batteries are available at most department stores. You will need to purchase Helium separately.
Department stores sell small inexpensive disposable tanks of helium with a filler attachment.
8 cubic feet is enough to fill one of these blimps and provide extra helium for topping-up. You may want to fill up your blimp at a Party Balloon store, but we recommend purchasing a small cylinder for the occasional top-up.
