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 adjustment 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, adjustment rings may become loose during operation and may have to be retightened.
If the brake drags, the brake pads and the brake disc wear out.
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 adjustment
rings on the brake linkage.
Carburettor linkage
A visual check of the carburettor barrel is possible after removing or before attaching the air filter.
If necessary, readjust idle position (carburettor barrel opened max. 0.7 mm) on the idle speed adjustment screw (choke end stop screw).
The idle speed adjustment screw is the little screw on the opposite side of the carburettor slide.
The throttle/brake linkage works as follows:
Full throttle (A): Carburettor slide fully pulled out, brake has no effect
Idle speed (B): Carburettor slide fully retracted, adjusting rings are loose on the brake levers.
Brakes (C): Throttle linkage presses against spring resistance, brake linkage presses forward against the fully moved brake lever.

Function check of the throttle/brake servo
• Move the lever of the remote control (channel 2) towards the back (full throttle position). The carburettor slide must now be completely pulled out, the
carburettor barrel opened to its maximum. The brakes are inactive.
• If the carburettor slide does not respond to the remote control, switch the servo reverse for channel 2 to "REV" to reverse the rotating direction.
• If the carburettor slide does not move completely, correct the servo travel at the trim (channel 2) of the remote control.
• Release the lever on the remote control.
Now the carburettor slide must go back to idle position (carburettor barrel opened approx. 1 mm).
The brake is still inactive.
• Press the lever of the remote control forward all the way (brake).
The carburettor slide must remain in idle position (carburettor barrel opened approx. 1 mm).
The servo lever at the carburettor linkage pulls against a spring resistance, the servo lever at the brake linkage controls the brake lever.
• Release the lever of the remote control again. Now the brakes should disengage again.
• You can adjust the brake linkage by moving the adjustment rings at the brake control lever accordingly.
