General Operating Instructions

Please read the complete instruction and safety manual carefully before operating the model. These are for your safety and can prevent accidents/injuries.

Powering On/Off Sequence

To Power On: Switch on the transmitter first, then the model.

To Power Off: Switch off the model first, then the transmitter.

Range and Signal Integrity

Never operate your model beyond your line of sight. Maximum visibility and range depend on factors like weather, location, and interfering frequencies. Therefore, perform a range test with a second person securely holding the model before each use. Also, check how the model reacts to signal loss (e.g., empty transmitter batteries).

Transmitter Overview

Diagram shows the Whelon 2.4 GHz remote control transmitter with numbered components.

Battery Installation: Open the battery compartment cover at the bottom, insert batteries observing polarity markings. Close the cover.

Charging the Model Battery

Diagram shows the car body, the battery pack, and the charging box with USB cable.

Step 1: Open the battery compartment covers and remove the batteries from the model (left and right on the chassis).

Step 2: Connect the charging cable to the battery box. Insert the USB plug of the charging cable into your PC's USB socket. The green LED will light up.

Step 3: Place the batteries into the charger box. The red LEDs will light up, indicating charging has started. When the red LEDs turn off and green LEDs light up, the batteries are fully charged. Follow safety instructions on page 7.

⚠️ Attention: If the LEDs start flashing, immediately remove the batteries. Flashing LEDs indicate that one or both batteries are damaged.

Important: Allow the battery pack to cool down for at least 10 minutes after operation before charging. For safety reasons, battery charging must be supervised at all times.

Operating the Model

To operate your model, switch on the transmitter first, then the model.

Press the ON/OFF switch for 2-3 seconds to switch the model on or off.

Your model binds automatically with the transmitter when both are switched on.

After operation, switch off the model first, then the transmitter.

Low Voltage Cut-Off

As soon as the battery voltage falls below 6.3V, the model is switched off. The model cannot be restarted until the batteries are fully charged.

Steering Operation

Diagrams show the car from above, demonstrating steering left, right, and straight.

Ensure good steering performance.

• To keep the car running straight, do not move the control wheel (keep it centered).
• Turn the wheel left to steer the vehicle left.
• Turn the wheel right to steer the vehicle right.

Control Functions

Throttle Lever

Diagrams show close-ups of the throttle lever being moved forward, backward, and to neutral.

• If the throttle lever is left in the center (neutral position), the model stops.
• Pull the throttle lever towards you: the model moves forward.
• Push the throttle lever away from you: the model moves backward.
• Moving the lever more or less controls the speed. During forward movement, quickly push the lever forward to brake.

Steering Trim

Diagram shows the steering trim control on the transmitter and the front wheels of the car.

Adjust the steering using the steering trim if the front wheels are not straight when the steering wheel is in the neutral position.

Throttle Trim (Beginner Mode)

Diagram shows the throttle trim control on the transmitter.

By adjusting this lever, you can increase or decrease the maximum speed of the vehicle.

Steering Reverse

Diagram shows the steering reverse switch and the effect on steering direction.

By switching the Steering Reverse switch, the steering direction can be reversed.

Chassis Settings (Suspension & Toe Angle)

These adjustments can enhance performance and tire wear. Make adjustments in small increments and note down original settings.

Front Steering Toe Angle

Diagrams illustrate the front wheels showing toe-in, zero toe, and toe-out angles.

The front steering toe angle can be adjusted by tuning the length of the steering linkage screwbolts.

• Toe In: Less reactive steering, tendency to understeer (front wheels push straight). This can be advantageous for operators struggling to get to grips with driving.
• Toe Out: More aggressive steering response, tendency to oversteer (rear wheels slide on small steering inputs). This is useful as a race tuning aid to gain extra steering.
• Zero Toe: Neutral steering, front wheels run straight. The vehicle will feel very neutral. Tire wear will also be reduced and the vehicle will feel easier to drive.

Adjustment Method: The toe angle is adjusted by rotating the adjustment screws. Ensure both screws are adjusted equally (left and right front wheel) to maintain balance.

Practice Driving

Diagrams show a car driving in an oval and a figure-eight pattern.

• Practice driving to achieve a large regular oval.
• Use empty cans as markers for a figure-8 drill.
• Decelerate when entering a curve and accelerate after the apex.

Keep practicing until you feel comfortable with steering, throttle, and brake at low speeds. Once you are comfortable, try operating on another track. When you have mastered the basics, you will be able to drive at higher speeds in a more controlled fashion.

Troubleshooting

Model Does Not Respond

• Check battery charge or condition. Charge or replace batteries.
• Check for a defective motor. Replace motor if necessary.
• Check for loose or damaged cable connections. Reconnect or replace cables.

Safety and Disposal Instructions

General Safety

Read all instructions and safety guidelines carefully before operating the model. This product is not intended for use by individuals with reduced physical, sensory, or mental capabilities, or lack of experience, unless supervised. The user is fully responsible for correct use. Do not modify the model. Protect from strong sunlight, moisture, and dust. Be aware that some parts may get hot. If the model, motor, or battery gets wet, clean and dry thoroughly in a shaded area. Keep the model away from children for whom it is not suitable. Do not operate near radio stations, power lines, or transformer boxes, as this can cause interference. Avoid driving in busy places or on public roads. Keep hands, hair, and loose clothing away from rotating or heated parts. Drive only in good weather; do not operate in wind, rain, or thunderstorms. Inspect the model before and after each drive for damage and loose connections. Ensure only an intact model is used. The model is made of plastic and rubber and is flammable; keep away from open flames and high temperatures. Always ensure the throttle stick is in the neutral position before powering on.

Battery Safety

Due to their high energy density, lithium-ion cells require special care. JAMARA explicitly excludes liability for damages resulting from improper handling of these cells. Incorrect use carries a risk of fire or chemical burns. Overcharging, excessive current, or deep discharge will destroy the cell. Protect from mechanical stress (squeezing, pushing, bending, drilling). Never open or cut batteries, do not throw them into fire, and keep them away from children. Handle damaged or leaking batteries with extreme caution, as injuries or product damage can occur. Under no circumstances short-circuit the device and always observe correct polarity. Protect batteries from heat above 65°C and mount them away from hot objects (e.g., exhaust pipe). Before storage (e.g., winter), charge the batteries but do not store them fully charged or fully discharged. Periodically check the charge level during long-term storage. The cell contents are harmful to skin and eyes. If contact occurs with skin, rinse with plenty of water and remove soiled clothing. If contact occurs with eyes, rinse with plenty of water and consult a doctor. If a cell overheats, swells, smokes, or burns, do not touch it. Maintain a safe distance and prepare adequate extinguishing agents (e.g., dry sand, fire extinguisher, fire blanket, salt water – NO WATER due to explosion risk).

Disposal

Batteries and accumulators must not be disposed of in domestic waste; they must be disposed of separately. You are obliged to return old batteries to appropriate collection points. Electrical appliances must also be disposed of separately from domestic waste. If personal data is stored on the appliance, you must remove it yourself.
