CEN Racing has changed the Nitro Sedan racing world. CEN introduces the all newly designed CT4. This State-of-the-art racing
sedan incorporates months of extensive testing from all parts of the world to bring you the fastest, most reliable car on the market.
This high-performance racing kit comes standard with all the upgrades and hop-up parts that racers demand. The CT4's on-track
performance surpasses all other models in its class. Many tuning options have been built into the chassis design to allow the driver
to adjust to any track conditions.
Please take your time when building this kit. There are many steps that require close attention to small details to ensure correct
assembly. Please build the car as instructed first. Then make changes to the set-up as the track conditions or driving styles require.
There are addition options available to further tune the car available separately from CEN Racing. All these items are available
through your local CEN Dealer.
For information on new products and upgrade parts, please check out our website at www.cenracing.com. If you have any questions
during assembly please feel free to call CEN Racing to answer any questions you may have.

@® This radio controlled model is not a toy. For yours and others safty, the following guidelines and cautions should be followed carefully.
WARNING: Do not operate R/C car in the following locations:
1. Street
2. Crowded area; keep away from children.
3. Indoors or an unventilated room.
SUGGESTION: Outside in a large open area without obstructions; R/C race track.
@This kit uses many Kinds of small parts, sharp tools, large polybag, and chemical materials. Please keep these and other potentially
harmful items away from children.
@Use only FCC approved ground frequency crystals in the R/C unit.
@®Do not operate a Gas powered car in a residential area. The noise could disturb the peace.
@!If you are operating several cars together, check the frequencies to make sure none are the same. Operating the cars on the same
frequency can cause radio interference and loss of control of the car.
@!If the car is not operating properly, stop immediately and check the condition of the car.
@To avoid damage to the R/C equipment, or losing control of the car, avoid running in or near water.
@To always maintain control of your car and to avoid a jump start, Please do the following:
1. ON - First turn on the transmitter, then the car's receiver. 2. OFF - Turn off the car's receiver, then the transmitter.
@Do not touch the R/C car after operation, as the engine, muffler, electric motor, battery, and speed controller will be very hot! Allow to
cool before handling. While charging your car's battery, it could become hot. Carefully read your battery charger's instructions for
proper use.
®When the R/C car is in operation, do not touch any of its moving parts such as drive shafts, wheel ,etc., as the rotating parts can cause
serious injury.
@After operation of the R/C car, it is necessary to remove the battery for protection of the R/C equipment.

Throttle linkage for CT-4 R
Now you need to do the final adjustments to your throttle linkage. You should have your linkage on the car as instructed in
step 6-11. Turn on your radio gear and proceed with the following steps. Leave the servo in neutral unless instructed to do
1. Loosen collet "C" and push the carburetor all the way closed (Push towards the rear of the car). Holding the carburetor closed
push the collet up against the rubber tubing, leave about 1-2mm gap and tighten the setscrew to secure the collet.
2. Loosen and adjust collet "A" and slide the collet to compress the spring. Compress the spring just enough to push the carburetor
all the way closed when the servo is in neutral.
3. Test your work by pulling full throttle, make sure the carburetor is completely opening up. Let go of the trigger the servo will go
back to neutral. Now push the brake, the carburetor should not close anymore. If it does then adjust using either the throttle trim
or put more pressure on the spring that pushed the carburetor closed.
4. Now with the throttle linkage setup adjust the drag brake using the adjusting nut at the end of the brake rod. Amount of drag brake
varies from driver to driver but start out with very little or no drag brake at all. Adjusting nut

1. Attach for first piece of fuel line from the carburetor to the fuel fitting next to the primer pump on the fuel tank.
2. Take a second piece of fuel tubing close to 12 inches long and connect it to fitting on the pipe then onto the pressure fitting on the
fuel tank.
3. Your finished car should look similar to the model pictured.
