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 deections.

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 gure 8, sketch A).

The servo lever is at an angle to the linkage rod (see

gure 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.
