The UH-1 Black Hawk 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 UH-1 Black Hawk 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 Black Hawk turning in the direction opposite to the rotation of the faster moving rotor. Since the UH-1 Black Hawk is fixed pitch, collective control is governed exclusively by throttle.

On the UH-1 Black Hawk, the roll cyclic is a bit more responsive than its pitch cyclic (fore/aft control). This is because the very small range of cyclic control can more easily roll the heli than it can pitch it along the length of the body. This attribute actually helps make the UH-1 Black Hawk stable. For a heli of this size, the responsiveness on both axes is appropriate.

For beginners, flying theUH-1 Black Hawk out of ground effect (first few inches off the ground) is not difficult either. Unlike other micros, the UH-1 Black Hawk tends to rise evenly rather than skate across the floor laterally. If you punch the throttle, it has no hesitation in climb either. The Li- poly battery will help to achieve better performance and longer flight time.
