The Exost Aquajet is a cool radio controlled product that can be transformed from a 4x4 car to a boat and back again. Go from the beach into the water, push a button on the hand control and the wheels go into the body. Start the engines that drive the dual propellers and drive around with the boat. Drive to the beach, push the button and the wheels go out and you drive a 4 wheel drive radio controlled car. With the Exost Aquajet you have both a radio controlled car and a radio controlled boat!
