Warning
RC Helicopters are complicated aircraft which can
not the mastered simply. They are aerodynamically
unstable and can fly in any direction if control is lost.
There is a constant danger of injury when operating
them.
Beginners are strongly recommended to find an
experienced modeller, club or model flying school.
Further advice is available from model shops and
modelling publications.
Preparations
Before reviewing the setting of the model into the
transmitter, the model should be set accurately using
the mechanical adjustments.
That is:
•
All controls are set in accordance with the
respective helicopter instructions.
•
All controls are assembled so that with the control
linkages at the middle position, and the trim
neutral, the servo arm is at a right angle to the
control rod.
•
With the control sticks centred, the main rotor
head is horizontal, and the tail rotor blades are at
the required pitch angle.
•
The size of the servo arm was chosen such that
the throttle control rod movement matches the
carburettor movement required between idle and
full throttle, and that the motor will idle with the
joystick fully back and the trim appropriately set.
The servo movement is unrestricted and does not
foul by appropriate mechanical or electronic
limits.
The user should familiarise himself with the
individual programs starting on page 66.
