* ADJUSTING THROTTLE LINKAGE BEFORE START THE ENGINE
SETTING THROTTLE LINKAGE
1. Turn on your transmitter at first and then the car's electronics (Set the transmitter trim-level in center).
Adjust the alum. stopper A to made the carburetor in idle position. Adjust the alum. stopper B to
leave 2mm space between alum. stopper and brake level.
2. Pull the full throttle trigger. The carburetor should be almost full open.
3. Apply the brake with your transmitter trigger, your carburetor should in idle position. The spring
between the alum. stopper and ball end should be compressed.
Notes:
1) Always check and change radio batteries when low. Running your car with low batteries
will greatly shorten the radio range. Loss of radio control will damage your car and is not
covered under warranty.
2) Check linkage operation for steering and throttle before starting your car. The directional
servo switches on radio may be in the wrong position and must be checked and set for
proper operation.
3) Battery problems are the biggest cause of car damage, always check radio operation when
running. If you feel the radio is not working correctly, shut down engine immediately and
check it out!
