12. Installing the Servos
The installation of a servo (1) always depends on the
particular model used. Detailed information on this can
be found in the construction documents of the model.
Generally, however, try screwing in the servos in a vi-
bration-dampened manner. This is why rubber bushings
(2) with metal sleeves (3) are usually included with the
servos.
When linkages are stiff, the servos cannot assume the
required positions. This causes higher power consump-
tion and the model cannot be controlled properly. The
linkages must work as smoothly as possible without hav-
ing any play in the bearings or deflections.
Before installing the servo lever, take the transmitter and
then the receiver into operation and check the trim at
the remote control transmitter for correct middle position
(see following chapter).
Then always mount the servo stick at a 90° angle to the
linkage rods (see figure 8, sketch A).
The servo lever is at an angle to the linkage rod (see
figure 8, sketch B), the control paths of the two control
directions will be unequal in spite of the same turning
angle.
A slight mechanical inclination due to interlock of the
servo levers may be corrected with the trim later.
