Rc Functions Of The Helicopter; Technical Data - Carson Marines HM-38 Instruction Manual

b. RC functions of the helicopter
GB
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
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 right 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.
