Inspired by the famous Chinook army helicopter, the Swann Military Thunder is super-fun and easy to use - bound to provide endless entertainment beyond the skies. The tandem set of dual, coaxial rotors offer a unique flying style that can be compared with a real Chinook! Stability, a lightweight build and a sensational low-torque control system make the Swann Military Thunder ideal to use indoors. It's also fully constructed and ready to fly - there is no setup or counterweighting required! The video game-styled controller features two analog control sticks and a trim controller - all of which can be operated with little or no practice. The Swann Military Thunder can be taken anywhere and fully re-charged on-the-go using the attachment on the remote control or from your computer's USB port.
