Function Check Of Servos - Reely ROAD Firestar Notice D'emploi

k) Function check of servos
Steering servo
The steering servo is connected to channel 1 of the remote control, i.e. to
the steering control wheel.
Construction of steering
The steering of the vehicle is designed as an axle leg steering.
The steering servo is installed upside down behind the front axle in a
recess in the top deck. The steering levers of the axle legs on the right
and left are each connected with a steering link half (1) with a ball head
bearing, the other ends of which are also screwed directly onto the servo
arm (2) with a ball head bearing.
The swivel motion of the servo arm effects the turning of the wheels via
the steering link halves. A servo saver (3) is integrated in the servo arm.
The servo saver compensates blows caused by unevenness to a wheel
and via the wheel to the steering so that the steering servo is not damaged.
The steering angle to the right and left is limited by a mechanical stop of
the steering arm against the axle leg support.
Function check
• Support the model at the front so that the wheels hang freely.
• Due to the wheels' good grip and the weight of the vehicle, the wheels
will not directly respond to the remote control if the vehicle is on the
ground. The response is as it should be when driving.
• First switch on the transmitter, then the receiver.
• Move the steering control wheel (channel 1) to the right and the left.
• The wheels must turn to the right and the left!
• If the wheels turn in the opposite direction, switch the servo reverse on
the remote control to the "REV" position (reverse).
• Release the steering control wheel. The wheels must turn back to
straight-drive position. If the wheels do not exactly assume straight-
drive position when the steering control wheel is in neutral position,
adjust the trim on channel 1. The end points of the steering control
wheel should cause the steering to fully go to the right/left!
Servo saver
The servo saver has already been pre-adjusted. Before first use it has to be checked and might have to be set tighter (so that the control commands
of the steering servo are carried out when driving quickly).
Throttle/brake servo
The throttle/brake servo is connected to channel 2 of the remote control.
Mode of action and throttle/brake linkage settings
The throttle/brake linkage carries out two functions at the same time via two servo steering levers that are at a 90° angle to each other.
Moving the carburettor slide via the throttle linkage regulates the air supply to the engine. At the same time, the idle jet needle (tapered needle of a needle valve)
is moved, which changes the amount of fuel flowing through the carburettor. If the throttle linkage is moved beyond neutral position (mechanical end point of the
carburettor slide), the servo lever pushes against a spring stop.
Now the sphere of action of the brake linkage comes to effect, it presses the brake shoes of the disc brakes together via an eccentric tappet.
The positioning of the adjusting rings (the mechanical end point), of the stop springs on the throttle linkage and the brake linkage are preset. They are adjusted
to the mechanical end points of the carburettor and the disc brakes. The gas/brake linkage should not require any readjustments.
However, adjusting rings may become loose during operation and need to be retightened.
If the brake drags, the brake pads and the brake disc wear out prematurely.
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 adjusting
rings on the brake linkage.
