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 con
-
struction documents of the model.
Generally, however, try screwing in the servos in a vibration-
dampened manner. This is why rubber bushings (2) with metal
sleeves (3) are usually included with the servos.
When servos are obstructed, the servos cannot assume the re
-
quired positions. This causes higher power consumption and the
model cannot be controlled properly.
The linkages must work as smoothly as possible without having
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 9, sketch A).
The servo lever is at an angle to the linkage rod (see figure 9,
sketch B), the control paths of the two control directions will be
unequal.
A slight mechanical inclination due to interlock of the servo levers
may be corrected with the trim later.
13. Setting the Trim
The trim mostly serves to correct the slight inclination of the servo levers due to the interlock and the connected ir
-
regular control movements. Additionally, there is the option of precisely adjusting the model in operation, e.g. if it is not
running straight although the control wheel is in the middle position.
Then the linkage rods must be adjusted so that the trim has its original value (90°-range between servo lever and
linkage) again and the model still runs straight.
The remote control „GT2 EVO“ has a precise digital trim in which each control channel can be adjusted individually
with two buttons each.
