Walkera Dragonfly 5-4 X-Factor Electric Radio Remote Control Helicopter, RTF

INTRODUCTION

Dragonfly 5 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 Dragonfly 5 turning in the direction opposite to the rotation of the faster moving rotor. Since the Dragonfly 5 is fixed pitch, collective control is governed exclusively by throttle.

On the Dragonfly 5, 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 Dragonfly 5 stable. For a heli of this size, the responsiveness on both axes is appropriate.

For beginners, flying the Dragonfly 5 out of ground effect (first few inches off the ground) is not difficult either. Unlike other micros, the Dragonfly 5 tends to rise evenly rather than skate across the floor laterally. If you punch the throttle, it has no hesitation in climb either.
