TEERING SERVO
The steering servo is connected with channel 1 of the remote control transmitter to the steering wheel.
Steering layout
The steering of the McFlash is designed as axis leg steering.
The steering servo is placed behind the front axle headfirst
in a recess on the top deck. The steering knuckles on the right
and left are each connected with a spherical bearing-supported
steering knuckle half, whose other ends are also screwed onto the
servo arm with a spherical bearing support.
The swivel motion of the servo arm effects the turning of the
wheels via the track rod halves. A servo saver (3) is integrated
into the servo arm. The servo saver compensates blows caused
by unevenness to a wheel and therefore the steering so that the
servo transmission is not damaged.
Turning right and left is limited by a mechanical stop of the steer-
ing knuckle arm against the axle leg support.
The rear wheels are also equipped with steering knuckles that
are permanently screwed onto the servo installation disk to sta-
bilize the wheels. An all-wheel drive function can be realized by
installing another servo into the rear recess.
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.
The gas/brake rods are already mounted and should not require any readjustment. However, set collars may become loose
in operation and must be retightened.
If the brake drags, the brake pads wear off as well as the brake disk.
In order to ensure that the brake is completely released, make sure that the brake control lever is located at a distance of
approx. 1 mm between the set collars on the brake rods. You can adjust the set collars by loosening the grub screws.
