Before starting

• Check with your insurance company whether the operation of a radio-controlled model is covered by insurance (liability insurance).
• If you have no experience in controlling RC models, first familiarize yourself with the reactions to the control commands on the stationary model.
• If necessary, contact an experienced modeler or a model club. Seek the assistance of an experienced pilot/driver if necessary.
• Check the radio control system and the model for functional reliability and visible damage, such as defective plug connections or damaged cables, before starting operation.
• All moving parts must function smoothly, but without bearing play. Check all screw and plug connections, wheel nuts, and electrical contacts for a tight fit, as these can become loose or detached during transport, while driving, or in minor accidents. Fasten excess lengths of cables so that they cannot get caught in moving/rotating parts. Cables must not be kinked. Make sure that all batteries are fully charged and not damaged.

Driving/ flying

• Do not drive/fly if your ability to react is impaired (e.g. if you are tired, or under the influence of medication or alcohol). Incorrect reactions can cause serious personal injury and property damage. Do not drive/fly if you have even the slightest doubt about the perfect technical condition of your model/remote control system. Always maintain direct visual contact with the model. Only operate the model on private property or sites designated for this purpose. Observe the requirements and regulations for the terrain.
• When operating a model, always ensure that no parts of the body or objects are in the danger zone of motors or rotating parts. of motors or rotating parts. Regularly check all screw connections and fasteners, as they may become loose or loosen during operation. Immediately stop operating your model in the event of a malfunction and eliminate the cause of the malfunction before continuing to use the model. Avoid driving/ flying in low outdoor temperatures, as this reduces battery capacity and causes the model’s plastic to lose elasticity and splinter easily. Do not expose your model and the remote control system to direct sunlight, moisture, heavy soiling, or great heat/cold for long periods. Do not drive in crowds, towards people or animals, in nature reserves, at night, under high voltage power lines, radio masts, or during thunderstorms.

1. On/off switch
2. LED
   • If the LED is constantly lit, the battery voltage is sufficient; if the LED flashes red, the transmitter batteries are empty and must be replaced (insufficient voltage).
3. Steering wheel
4. The throttle/brake lever
5. 3rd switching channel
6. Steering trim
   • If the model does not go straight without steering, you can adjust the straight run through the trim.
7. Dual rate steering
   • Using the dual rate, you can continuously reduce the maximum steering deflection of the model. By turning the potentiometer the servo travel is increased or decreased.
   • Please note that the servo never jams or may press against an obstacle, reducing the steering deflection in this case.
8. Throttle trim
   • If the model moves by itself without you operating the throttle, you can adjust the neutral point (standstill) through the trim
9. Dual rate throttle
   • Through the switch, you can select the maximum power of the throttle channel between 100 – 75 – 50 %. At e.g. 50 %, only 50 % maximum speed of the model/controller is released when the throttle lever (4) is fully pulled.
10. Servo reverse
    • By means of the switch, you can reverse the control direction of the steering servo/controller (throttle). If the servo steers in the wrong direction when you turn the steering wheel, you can change this simply by switching.

Receiver

Technical data

• FHSS 2.4 GHz / 33,5×21,5×12,5mm / 6 g / 4.5-10 Volt
• AUX) Auxiliary channel
• Additional channel for special functions, to be operated via switch “5” of the remote control.
• THR) Throttle channel (speed controller)
• STR) Steering channel
• BIND) Binding channel
• If you use a new receiver/transmitter or the remote control loses the binding to the receiver (no function of the model on control commands), you must establish a new “binding” between the transmitter and receiver.

Proceed as follows:

• Turn off the transmitter. Plug the binding cable (B) into the BIND connector on the receiver. Now switch on the power supply of the receiver (controller). The LED on the receiver will begin to flash rapidly.
• Turn the steering wheel of the remote control to the right and hold this in position, now switch on the transmitter. The LED of the transmitter flashes and releases the steering wheel again.
• The flashing of the LED on the receiver stops and is now constantly lit. Switch off everything and disconnect the binding cable (B) again.
• Never extend or shorten the receiver antenna! Do not continue to use the receiver if the antenna is damaged! This can lead to malfunctions and accidents!

Fail-Safe

• You can program a Fail-Safe on your RACE X3 remote control. This prevents your model from driving/ flying uncontrolled etc. in the event of a malfunction.
• You can program what the individual channels should do in the event of a malfunction as follows.
• Turn on the transmitter and receiver and make sure they are bound. Now press/turn the steering, throttle, and AUX settings on the remote control as you would like the system to do in the event of a malfunction (we recommend setting steering neutral, AUX neutral, and throttle to brake – in this case, the model would simply brake and then stop in the event of a malfunction).
• Hold the desired positions on the transmitter and at the same time plug the binding cable (B) onto the BIND connector of the receiver.
• The receiver LED will now flash 3x. The fail-safe is now programmed. Remove the binding cable again, switch everything off, and reconnect the units such as the servo, controller, etc. to the receiver.

Insert battery

• The drive battery of your model is located under the body in the battery compartment. Remove the cotter pin from the bodywork and remove it.
• This way you can reach the battery compartment. Now plug the battery into the controller (red plug).
• The model’s on/off switch is also located on the controller unit.
• If the model is not used, always disconnect the battery and remove it from the model!
• The model is equipped with a NiMH battery (7.2 volts). The model is not approved for operation with a LiPo battery (7.4 volts), the motor wear is too high in this case and leads to motor damage.

DF Models is registered under the WEEE Reg. No. DE30915550 at the EAR foundation and recycles all used electronic components properly. Betterier registration: DE69664807. Batteries/rechargeable batteries are marked with the symbol shown below (waste garbage cans). This indicates that disposal of household waste is prohibited. Additional designations for the decisive heavy metal are Cd=cadmium, Hg=mercury, and Pb=lead.

storage

• Batteries should not be empty or fully charged during longer storage. A state of charge of approx. 80 % of the rechargeable batteries is ideal.
• The state of charge should be checked and adjusted at regular intervals.
• Always store batteries safely in a non-flammable place (e.g. use LiPo bag etc.). Store and keep at room temperature (approx. 15-22°C).

charging

• Batteries may only be charged with suitable chargers. For Lixx batteries only charge with chargers with connected/integrated balancer! LiPo batteries have a final charging voltage of 4.2 volts/cell, and NiMH batteries of 1.45 volts/cell.
• Accus should be charged with a charge rate of 1 C, higher charge rates can shorten the life of the battery.
• Charge rate: capacity x C-rate = charge current (example with 1C charge rate: battery with 1000mAh x 1C charge rate = 1000mAh (1 A) charge current)
• Maximum temperatures when charging batteries: LiPo max. 45°C | NiMH max. 60°C
