3. For helicopters
3.1. Helicopter mixers
If you select the model type H (Heli) in the menu point RESET of the MODEL menu,
you can now select either of two types of rotor head to control.
v Rotor heads with mechanical mixing
v Rotor heads with 120º mixing
You should use this section of the instructions as a guide when setting up your
helicopter. We have arranged the individual steps in the procedure in the most
practical sequence.
3.1.1. Introduction
Safety notes
Radio-controlled model helicopters are complex flying machines which are not easy
to master in the air. Operating such models incompetently or irresponsibly poses
serious hazards.
If you are a beginner, please heed our advice:
v Ask for help from an experienced model pilot, your local model club or model
flying training centre.
v Ask for help from your local specialist model shop.
v Read all the literature on helicopters that you can find.
Rotor head types:
The C
is suitable for helicopters fitted with the following types of rotor head:
OCKPIT
MM
v Rotor heads with mechanical mixing
Separate servos are used to control the functions COLLECTIVE PITCH, ROLL and
PITCH-AXIS.
v Rotor heads with 120º linkage
The swashplate is operated by three servos, arranged at
120º to each other
The pitch-axis servo (4) may also be located in front of
the rotor shaft (relative to the direction of flight).
The method of setting up the Cockpit for the second
rotor head type is described in the step-by-step
instructions in Section 3.2.1, point e).
3.1.2. C
OCKPIT
MM
v Collective pitch-throttle mixer
When a helicopter climbs (increased collective pitch angle) the throttle setting
must be increased in order to maintain constant system rotational speed. This
mixer (COLLECTIVE PITCH to THROTTLE) is automatically activated when you
select the model type Heli H (è 3.2.1, point a)).
