The Swann Air Force is the big daddy of indoor RC choppers. It looks and flies like a real army helicopter with green livery and military markings and once it takes flight it dominates the sky. The Air Force has a built-in rechargeable 7.4V Lithium battery that charges in 90 minutes directly from mains power to give you 8 to 10 minutes of exhilarating flying time per charge. The remote control transmits using a powerful 27MHz radio frequency allowing the chopper to fly higher and further than most indoor helicopters, up to 100ft (30m). With super-responsive flying capabilities, it's perfect for experienced RC chopper pilots of advanced skill level. Use the 6-way multi-directional remote control to fly up, down, backwards, forwards and make left and right turns. You can also fine-tune the Air Force's movement through the digital trim control and vary flight speed using the throttle control stick. Join the Swann Air Force for a combination of power, distance and maneuverability that will keep you entertained through countless flights and indoor air battles.
