CARB LINKAGE ADJUSTMENT
Turn on transmitter and receiver and set the throttle servo trim to the neutral position.
Adjust the idle adjustment screw on the carburetor to open approx. 0.5-1mm.
Adjust both collars on the carb and brake linkages accordingly. The carb linkage must have approximately
0.5mm of preload on the spring at neutral.
DO NOT ADJUST while the engine is running.
With the engine NOT RUNNING but the receiver turned ON, apply full throttle at the transmitter.
Adjust the transmitter‘s throttle servo high-end point so that the servo horn fully opens the carburettor when the
transmitter‘s throttle control (e.g., throttle trigger) is at 95% of full throttle. The servo should not have excessive
strain when at full throttle, or throttle/carb damage will result.
If the transmitter does not have throttle high-end point adjustment, adjust the throttle linkage pivot position on the
servo horn until full throttle is obtained.
Adjust the composite collar on the brake linkage so the brakes work smoothly.
If the brakes apply too much or not enough, adjust the collar accordingly. If your transmitter has throttle servo low-
end point adjustment (or brake adjustment), use that to set the appropriate amount of throttle servo horn throw.
