Dual rotor electric helicopter with an option to install a wireless camera (not included) for live viewing on your PC monitor or TV. The 4 CH Eagle Eye is a beginner-friendly rc helicopter enjoyed by inexperienced/experienced flyers. Its unique design makes it easy to configure, control, and more fun to fly. It is designed to train pilots and entertain them by delivering a stable flying platform capable of controlled indoor and outdoor flight course. The 4 CH Eagle Eye has two sets of main rotors and a freewheeling tail rotor that does not affect flight. The counter-rotating main rotors eliminate the need for tail rotor compensation because they move in opposite directions, canceling each other’s rotational torque. In addition, the blade sets give it an added bit of gyroscopic stability, which allows mere mortals to hover it with prowess.The lower rotor provides cyclic control for the heli. To yaw the helicopter (left and right), one of the main rotors either slows down or speeds up to create an imbalance in torque. This results in the Eagle Eye turning in the direction opposite to the rotation of the faster moving rotor. Since the 4 CH Eagle Eye is fixed pitch, collective control is governed exclusively by throttle. Details here >>>.
