a) Steering Function

The steering servo is connected to channel 1 of the re-
ceiver and is moved by turning the steering wheel at the
transmitter.

steering.
The pivoting movement of the servo control lever (A) has
an effect on the steering linkage (B) and on one arm of the
D
servo saver (C).
The servo saver consists of two right-angled levers (C and
G
D), which are not rigidly coupled but can be moved against
F
each other via a spring on one level with the steering lin-
kage.
The second lever arm of the servo saver (D) moves the
middle part of the track rod, the steering plate (E).
It leads to a movement of the track rod (F), which causes a steering deflection of the wheels.
When hard impacts are transmitted through the track rod during operation, they are not immediately transmitted to
the steering servo, but are absorbed with the help of the resilient connection of the two lever arms (C and D) of the
servo saver.
The effect of the servo saver can be adjusted with a knurled nut (G) by modifying the contact pressure on the two
lever arms.
If the setting is too tight, the servo saver is useless. Impacts on the steering are forwarded to the servo undampened
and may destroy the servo gear. Too weak a setting has negative effects on driving behaviour, since, e.g., even small
potholes will strongly change the steering angle. The vehicle can barely be driven straight ahead here.
Turning left and right is limited by a mechanical stop of the steering knuckle arm against the axle leg support.
If the transmitter used permits the servo path to the left and right should be limited accordingly so that the steering
servo does not run to block („running to block" means that the servo tries to turn the servo arm further even though it
is already being blocked by the steering mechanics. This leads to an unnecessarily high current intake of the steering
servo as well as to overload and damage to the servo gear).
