Last year Silverlit had brought to all RC fans a major shock with the introduction of their Tandem Z helicopter. A full 3 channels control makes it capable to go forward, left, right, slightly backward. This year Syma had finally introudced their own version of Tandem Z, built with the coaxial blade platform, it provides double the stability in compares to a Tandem Z, you don't need to trim the helicopter constantly to get it stable. And you can manually adjust the flying style. 

Details

Instructions:

If you want the helicopter to lean more to the forward, you can press the button on the right shoulder a few times, it will make the Rear rotor Blade spins faster than the front rotor, making the helicopter tends to fly forward. And vice versa, if you want the helicopter to fly significantly backward. And you can also try the neutral flying mode, which is the easier mode to control the helicopter not leaning to either forward or backward!
