This is the newest 2009 version of the 4CH Colco Apache V3 with improvements. This Apache is a beginner-friendly helicopter that are also liked by experienced flyers. Its unique design makes it easy to configure, control, and more fun to fly. It is designed to both train pilots and entertain them by delivering a stable flying platform capable of controlled indoor and outdoor flight. The Apache 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 Apache turning in the direction opposite to the rotation of the faster moving rotor. Since the Apache is fixed pitch, collective control is governed exclusively by throttle.
