Equilibrating the model
The helicopter must be correctly balanced. If there is an incorrect
location of the centre of gravity, you lose the control over the model!
The location of the centre of gravity of the model is preset. Corrections
are only necessary if you are not satisfied with the flight characteristics.
The centre of gravity of the helicopter-model should lie exactly in the
rotation point of the rotor axis.

Shift the airplane battery in order to determine the optimal location of
the centre of gravity.
• Hang the helicopter on the upper rotor head, in the extension of the
axis of rotation. The helicopter may not tip forwards or backwards,
no matter in which position the principal rotor blades are located.
• If the nose drops, then the model is top-heavy. Shift the airplane
battery slightly backwards.
• If the tail sinks, shift the airplane battery forward in order to adjust
the centre of gravity.
Secure the airplane battery when you have determined the optimal
location of the centre of gravity.
Fastening the rotor blades
The rotor blades must be able to align themselves 180° to each other
solely by the centrifugal force.
• Therefore check the seating of the retaining screws (a) of the rotor
blades:
The screws may only be tightened firmly enough that the rotor
blades still fold downwards when you tip the helicopter to the side.
• The steering lever (b) for adjusting the rotor blade on the upper
rotor rotation cannot be set.

Switching on the model
Ensure sufficient space in order to undertake the first flight
experiments. Even if the indoor helicopter can later be flown in the
smallest quarters, it requires about 3 m free space in all directions.
• Set the model on a smooth and level surface, so that the
helicopter can freely glide and lift off.
• Set the helicopter about 2 m in front of yourself on the ground,
the tail pointing towards you. This way the direction of reaction
of the helicopter conforms to the direction of control.
• Unwind the receiver antenna completely and fasten the aerial
wire with an adhesive strip to the fuselage for traction relief.
• Pull the left remote control lever (pitch) totally back.
• Take care that the pitch function of the trim lever is approximately
in the middle position.
Attention!
• Connect the charged airplane battery to the helicopter.
• Not until now you can switch the transmitter on.

Lateral equilibration
Support the helicopter at the end of the tail beam and front on the
longitudinal axis as far as possible. To do this, remove the cabin hood.
The helicopter may not tip to one side, no matter in which position the
principal rotor blades are located.
