The Swann Bubble Bomber RC Helicopter is equipped with a specially designed undercarriage that allows you to drop bubbles from it using the included radio controller. Additionally, it features 6-way multi-directional control for fast indoor flying and maneuverability. The Bubble Bomber comes ready-to-fly (RTF) out of the box with no assembly required—just install six AA batteries into the pre-bound controller, and you're ready to go. The helicopter's built-in LiPo battery can be fully charged in 45 minutes directly from the radio controller or through the included USB cable and yields a 7-minute flight time per full charge.
