UNCTION CONTROL OF THE

TEERING SERVO
The steering servo is connected with channel 1 of the remote control transmitter to the steering wheel.
Structure of steering
The steering of "MAMMOTH Pro" is designed as axle leg
steering.
At the same time the steering knuckle arms are connected with a
three-part steering link.
The pivoting movement of the servo control lever (1) has an effect
on the steering linkage (2), on one (3) of the two rigidly cou-
pled, right-angled levers which are attached rotatably to an axle
between RC mounting plate and chassis plate in the same plane
as the steering rod. The second lever arm of the servo saver (3)
steers the centre part of the steering link, the steering plate (4),
and in this way causes the wheels to turn via the steering link (5).
When hard shocks are carried in via the steering link during opera-
tion, they are not immediately transmitted to the steering servo,
but are absorbed with the help of the resilient connection of the
two lever arms of the servo saver.
The effect of the servo saver can be adjusted with a knurled nut
(6) by modifying the contact pressure on the two lever arms.
Turning right and left is limited by a mechanical stop of the steering knuckle arm against the axle leg support.
Function control:
- Support the model at the front in a way that allows the wheels to hang freely.
Because of the good adhesion of the tires and because of the weight of the vehicle, in the stand and
on the ground, the wheels will not follow your steering spontaneously and directly.
This however changes during operation.
- First, switch on the transmitter, then the receiver.
- Move the steering wheel (channel 1) towards the right and the left.
Now the wheels must drive in towards the right and the left!
If the wheels turn in opposite direction, change the Servo Reverse on the remote control
to position "REV" (Reverse).
- Release the steering wheel; now the wheels must turn in straight line again.
- If the wheels do not stand straight when the steering wheel of the remote control is in neutral position, correct
the position by adjusting the trim on channel 1.
The steering wheel limit stops must limit the right / left limit stops of the steering!

HROTTLE RAKE SERVO
The throttle/brake servo is connected to channel 2 or the remote control transmitter.
Mode of action and setting of throttle/brake linkage
With the throttle/brake linkage two functions are carried out at the same time via two servo steering levers.
By sliding the "carburettor slide" via the throttle linkage, the air supply to the engine is regulated.
At the same time, the idle nozzle needle (conical needle of a needle valve) is moved, thus, changing the amount of fuel that
flows through the carburettor.
If the throttle linkage is moved further than the idle position (mechanical limit stop of the carburettor slide),
the servo lever pushes against a spring buffer.
Now the sphere of action of the brake linkage comes to effect, it presses the brake shoes together via an eccentric tappet.
The positioning of the adjustment rings (the mechanical limit stops) of the stop springs on the throttle linkage and
on the brake linkage are adjusted ex works and tuned to the mechanical limit stops of the carburettor and the
disk brake.
