Controlling the Hornet is a breeze and great for people of all skill levels. The Hornet features a coaxial rotor, a single rear rotor for precise turning, and an IR motion-sensitive technology that detect nearby objects and is programmed to move away from them. On the transmitter, you press the motion sensor launch button to get started, hold your hand underneath the helicopter to keep it hovering up in the air and when you’re done you can turn it off by pressing the motion sensor land button. The LED lights brighten up the night sky when flying. No assembly required!
