12. Installing the Servos
The installation of a servo (A) always depends on the
model used. For specific information, refer to the design
documents of the model.
However, generally you should try to fasten the servos
with screws in such a way that vibrations are minimised.
For this purpose, servos are usually provided with rubber
grommets (B) with metal sleeves (C).
In case of stiff linkages, servos can not run in the required
position. They consume excess power and the model con-
trol behaviour will not be correct.
The linkages must work as smoothly as possible without
clearance in the bearings or deflections.
Before mounting servo levers, operate the transmitter and
then the receiver and check the correct middle position of
the trimming on the remote control transmitter.
Always mount the servo levers at a 90° angle to the link-
age rods (A).
If the servo lever is inclined towards the linkage rod, the
control travels will have a different size (B) in both control
directions.
A slight mechanical inclination, which is due to the linkage
of the servo lever, can be corrected later with the trimming.
