Rc Functions Of The Helicopter; Technical Data - Carson Agusta Westland Grand Instruction Manual

b. RC Functions of the Helicopter
The following functions are controlled
with the two remote control levers of
the portable transmitter.
For every control function there is a trim slider on
the remote control transmitter which permits minor
GB
corrections of the neutral position.
Pitch function
(Ascend/descend)
The pitch function controls the flying height of this
model helicopter over a common variation in speed
of the two rotors. The control takes place with the
left control lever. To do this, move it forwards and
backwards in a continuously variable fashion.
Contrary to the other control functions this lever does
not spring back into the middle position. If the control
lever is totally drawn towards the back, then the motors
are off and the rotors stand still. If the control lever is
pushed forward then the motor starts running and the
rotors run with increasing speed depending on the
lever position.
In the middle position of the control lever, the helicopter should hover
at a fixed height.
Tail function
(Rudder function)
The tail function causes a rotation of the model around the vertical
axis. Since the helicopter has two opposed rotors, no torque ensues
around the vertical axis at the same speed of the rotors (rotor shaft).
The helicopter also therefore requires no tail rotor for stabilization. In
order for the model to be able to rotate around the vertical axis (rotor
shaft), the rotors must run at slightly different speeds. The resulting
torque introduces the rotation.
At less speed of the steering rotor compared to the bearing rotor, the
torque of the bearing rotor is greater, the helicopter turns around the
vertical axis in the direction of rotation of the steering rotor. At higher
speed of the steering rotor, the torque of the bearing rotor is less than
that of the steering rotor and the helicopter turns in the direction of
the bearing rotor.
The tail function is controlled with the left control lever. If the lever is
moved to the left, the tip of the fuselage turns to the left. If you move
the lever to the right, the tip of the fuselage likewise turns to the right.

Roll function
(Aileron function)
The roll function causes the lateral flight of the helicopter.
The control takes place with the right control lever.
If the lever is moved to the left, then the model hovers laterally to the
left. Moving the lever to the right makes the model move laterally to
the right.
Nick function
(Elevator function)
The nick function causes forwards and backwards flight of the
helicopter. The lower rotor rotation tips slightly downwards and
the model tilts around the transverse axis. When the nose drops
downwards, a part of the lift is transferred into forwards thrust.
If conversely the nose is raised, then the model flies backward. The
control takes place with the right control lever.
Press the lever forward to introduce forwards flight, pull back to have
the model fly backwards.
