Conquer land and sky by picking up a 2-Pack of the Sigma 2CH RC Helicopter! One of each color is included. The Sigma features a coaxial main rotor as well as dual rear thrusters. Hit the throttle in Sky Mode and fly this heli in the air. Once on the ground, toggle the Sigma to Land Mode and drive it around like a car. Switching between flying in the sky and driving on the ground happens with the push of a button. The Sigma helicopter charges directly from the controller.
