Equilibrating The Model; Fastening The Rotor Blades - Carson Agusta Westland Grand Mode D'emploi

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 of the rotor
blades:
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.
The screws may only be tightened firmly enough that the rotor blades
still fold downwards when you tip the helicopter to the side.
