SAFETY PRECAUTIONS

Safety Instructions and Intended Use
This product is designed exclusively for hobby use and may only be used on tracks and areas intended for this purpose. No persons or animals may be transported with this model. To avoid operator errors, it is mandatory that the user manual is read before use! These models may only be used with bodywork that is correctly fitted. When removing the bodywork, please note that, during operation, certain parts can become very hot. Please note that various models can generate very high noise levels and should, therefore, not be operated in your immediate proximity. Please make sure, before every driving session, that the tank is correctly closed or the power pack is correctly inserted. To avoid faulty operation of the control system causing the model to run out of control, it must be checked that the transmitter and model batteries are in good condition. It is essential to check that the model is correctly assembled both before and after use; if need be, tighten nuts and bolts.

This model is not a toy!

• This product is not a toy, its operation must be learned step by step
• Children under 14 years of age should operate the model only if supervised by an adult.

Operating RC models is a fascinating hobby that, however, must only be exercised with proper precautions and care. Since the weight of this model is considerable and it can reach a very high speed it can, if it runs out of control, cause significant damage and injury for which you, as the operator, are liable. Only a correctly assembled model will work and react as expected. Never improvise with unsuitable materials but, when the need arises, use only original spare parts. Even if the model is pre-assembled, all joints and fastenings should be checked for correct seating and tightness.

Before use, you must make sure of the following points:

• All rechargeable batteries must be fully charged.
• Before starting, check the radio range.
• Check that the model reacts correctly to the control signals.
• All functional parts of the product are in faultless condition and have been checked.
• All screw fastenings are firmly seated.
• Do not drive under high-voltage power lines or radio masts or with nearby thunderstorms!
• Atmospheric interference can influence the operation of your model.
• The electrical parts of the model are not water-tight. Do not, therefore, drive it in rain or snow or through puddles or wet grass.
• The remote-controlled model may be driven only on suitable areas and must not be used on the public highway.
• Do not use near people or animals!
• Do not use it when tired or if your reactions are otherwise impaired.
• Always maintain direct visual contact with your model.
• Regular maintenance and care are required for firt class driving performance.
• The model has parts that become hot in operation, e.g. the top of the motor, the metal gearbox, amongst many others. Touching these parts during operation can cause injury.

Pay attention to the charge level indication on your transmitter.

• With power packs or batteries that are half discharged, you can lose control of the model.
• In the transmitter, never mix fully charged batteries, rechargeable or not, with half discharged batteries or rechargeable batteries of different capacity.

CHASSIS

PLUG-IN RECEIVER BATTERIE

Make sure positive (+) and negative (-) ends are facing the correct direction. Then plug the pack into the switch harness, inside the radio case. Black goes to black and red goes to red. Replace the radio case cover.

CHECK 1… 2… 3…

Always turn the radio on before turning your car on. Now you can switch on your car using the on/off switch located on the radio box. Note: Always check your radio settings before running your car!
Check to make sure your steering is centered. If it is not, use the ST-TRIM knob to the left of the steering wheel. Turning left should make the car turn left. Right = right. Now it’s time to set the throttle to the neutral position. Remove the air cleaner from the carburetor. The opening on the carb slide should be open very little, from 1-1.5 mm to allow the engine to idle (picture 2). If it is open more than this, the engine may rev higher than normal until brakes are applied. This condition may wear out the brakes and/or clutch shoes prematurely making the car difficult to drive. Use the TH-TRIM tab (picture 3) to move the servo arm into the neutral position if necessary. While in neutral, the brakes should not be set to “drag”. Adjusting the collars with a 1.5 mm hexagonal wrench will change your drag brake settings. Replace the air cleaner when everything is adjusted to your satisfaction.

FINAL PREPARATIONS

Assemble the fuel bottle. Fill the fuel bottle by compressing it and then insert the spout into the fuel. Allow the bottle to decompress and the suction will fill the fuel bottle. Fill the tank by gently squeezing the bottle and ensuring that the tank lid is firmly shut when finished.
Racer Tip 1:
Fuel will stay fresh longer if you store it in a cool, dark and dry place.
Racer Tip 2:
Never leave the glow heater on your engine for more than 10 seconds. A longer time may cause the glow plug to burn out pre-maturely. Use rechargeable glow heaters for longer life.
Racer Tip 3:
To start the motor, use a fireproof glove!

SHOWTIME… ALMOST!

Engine break-in is the most important step to assuring that your engine is fast and reliable throughout its life. Put simply: DON’T SKIP THIS PART! The engine is pre-set from the factory for break-in. Use a “FAT BONE” 50 090 5034 or platform and place the car so that the wheels are off the ground and free. Make sure the throttle is set at neutral with your radio. Place the glow heater onto the glow plug and give the recoil a sharp pull (picture 4). Do not pull it more than twelve inches! More than that may break the cord and this is not covered under warranty. It is better to give the recoil short sharp pulls rather than long ones. If the pull-start cord gets stuck, rotate the flywheel a little bit with your finger. This should make the cord automatically recoil. Within a few pulls, the engine will start with a good puff of smoke.

If the engine has trouble idling at the rich setting, turn the idle screw clockwise 1/8th of a turn at a time. This will increase the idle allowing the car to break in properly. Try to do this in a well-ventilated area, such as your driveway. Unburned oil from the fuel will accumulate under the exhaust, so be prepared. Let the car idle like this for 2 – 3 tanks of fuel checking the engine temperature every 2 minutes. Please allow a break of 10 – 15 in between filling the tank to allow the engine to cool down. You should be able to touch the head of the engine with your fingertips and it will be hot, but not uncomfortably so. (Attention! Do not touch!) If it seems very hot, richen (turn counter-clockwise) the high-end and low-end needles 1/8th of a turn (picture 6). Always use small increments when making these kinds of adjustments.
Racer Tip:
Factory setting of carburetor:
With the following basic adjustment, the engine starts immediately, running perfectly and rich enough (outside temperature 8°C).

• Idle stop screw: approx. 1 mm air gap;
• High-speed needle valve: screw in completely, then open 4 full turns (picture 6);
• Low-speed needle valve (linking, picture 5): flush with the edge of the linking arm, then 1 full turn clockwise;

After the run-in is finished the high-speed needle valve should be open at least 3 and 1⁄4 turns. A richer setup is better if outside temperature is high.

Racer Tip:
Drive your car slowly with the rich setting shortly after the break-in period avoiding prolonged periods at full throttle. Gradually lean out the mixture 1/8 of a turn at a time. The idle will increase the more you lean the engine out.

TURN THE POWER SWITCH ON

Pull the transmitter antenna out completely.
The range of the remote control is reduced if the antenna is not pulled out completely.
CAUTION!
Always turn the transmitter´s power switch ON first! Switch on the receiver

• The power switch is on the radio box.
• Fix the receiver antenna and wire.
• Put the body on and fix it with the body split pins.

HOW TO CONTROL YOUR MODEL

• Raise the tires off the ground
• Turn the steering wheel to the right and left as far as it will go. The wheels are to follow the steering direction.
• If the wheels operate in the opposite direction, operate the servo Reverse switch (ST in position REV).
  • To regulate the driving speed, actuate the throttle/brake
  • backward (forward driving, accelerating) or
  • forwards (braking, reversing)

CARE AND MAINTENANCE

Failure to follow break-in procedure and/or damage caused by improper tuning will void your engine warranty. There are two ways to “temp” your engine. One, purchase a temperature gauge. The second cheaper, but less accurate method is the “Spit Test”. Wipe a little bit of saliva on the engine head and it should burn off in 3 – 4 seconds (the boiling point of water normally is 100 °C). If it evaporates immediately, chances are the engine is running too hot. The engine will run best and be easier to restart if run around 100-125 °C. Depending on your weather conditions, air density, and humidity, your carburetor settings will be changing wherever you decide to run. Making adjustments in small increments is the best way to make sure your engine lasts a long time. Overheating is caused by running the engine too lean, or too much stress on the engine created by the environment. Extreme overheating will result in the internal failure of engine parts. There are many online resources that will help you with engine tuning. 3,5 ccm engines are designed to last a long time, and with proper maintenance and tuning, you can drive the model for hours at a time.
After Use
When you have finished running your car, there are two options to shut the engine down. The first method is to place your thumb over the exhaust outlet (Wear gloves). Make sure your engine is normally idle, preferable with the brake activated. The second method is to pinch off the air supply from the engine. Do not pinch the fuel line, as this may cause the engine to overheat! Try and let all the remaining fuel run ough the engine, emptying the fuel tank. The engine will idle high while the tank is emptied, so the above two steps may not be necessary.

Then apply after-run oil through the carburetor, and pull the pull-start a few times to get it through the engine. This is recommended if you plan on storing the car for more than a day. Methanol evaporates in water and can cause internal corrosion to engine parts. It is always a good idea to check all the screws, nuts, and bolts before and after each period of racing.

Keeping the car clean will also make it more fun to work on. This can be achieved with a large heavy-duty paintbrush or compressed air. Always test the transmitter and receiver batteries before starting the engine.
Racer Tip:
Wear gloves when working on your hot car!
