3. Product Description
The double rotor RC electric helicopter is equipped with two counter-rotating main rotors and is ready to fly. Thus,
there is no torque around the yaw axis and the model does not need a functional tail rotor. Steering around the yaw
axis is effected by means of different revolutions of the two main rotors. Thus, the helicopter can turn around the rotor
shaft to either side
The upper main rotor is a bearing rotor and has a fixed attack angle, which is set automatically via the rotating
centrifugal weights. The lower rotor is a control rotor and allows flying in all directions.
Lifting and lowering the model is effected via a common modification of the number of revolutions of both main rotor
blades. Due to the big distance between bearing rotor and model centre of gravity, this model flies very stably and is
thus suitable as training model to learn flying with remote controlled model helicopters.
The radio remote control installation included in the delivery allows a sensitive steering of the model. 4 Mignon batteries
or Mignon rechargeable batteries are necessary to operate the transmitter.
