his is newest 4-Channel UH-1 Twin-Rotor-Coaxial helicopter. This helicopter is one of the newest dual-rotor in the market. The Twin-Rotor-Coaxial-Twin-Rotor design the helicopter has excellent stability taking off and it's easy to control. The UH-1 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 UH-1 turning in the direction opposite to the rotation of the faster moving rotor. Since the UH-1 is fixed pitch, collective control is governed exclusively by throttle.
