How the RC Dragonfly WorksHow the RC Dragonfly Works
Helicopters generate lift Helicopters generate lift by creating a pressure by creating a pressure differential across the differential across the bladeblade
The motion of the swash The motion of the swash plate regulates the plate regulates the forward, backward, left & forward, backward, left & right motionright motion
Yaw is controlled by the Yaw is controlled by the speed of the tail rotorspeed of the tail rotor

Flybars work in Flybars work in conjunction with the conjunction with the swash plate to guide swash plate to guide the roll & pitchthe roll & pitch
Servo motors control Servo motors control the motion of the the motion of the swash plateswash plate
This is a fixed pitch This is a fixed pitch model, meaning the model, meaning the main rotors are rigid main rotors are rigid to the shaft.to the shaft.
