• Switch on the transmitter. The control LED of the transmitter should light up brightly. If it does not light up, check the batteries and, if necessary, replace them.
• Switch on the receiver using the switch on the cover of the RC box. The servos should assume neutral position.
Always observe the right order when switching on/off the transmitter and the receiver!
Switching on: Always switch on the transmitter first, then the receiver.
Switching off: Always switch off the receiver first, then the transmitter.
i) Failsafe module
The fail-safe is inserted between the servo connection of the receiver and the throttle/brake servo. The fail-safe can save a specific position of a connected
servo. When the transmitter signal is lost or when the receiver batteries are low, the fail-safe moves the servo to the saved position.
Switch on the transmitter first, then switch on the receiver. The LED on the fail-safe starts flashing regularly with short light-up phases to indicate it functions
properly. Move the servo via the transmitter to the desired position to which the fail-safe should move the servo when the transmitter signal is lost.
Shortly press the button on the fail-safe. The current position of the connected servo is saved.
The fail-safe now has two different functions:
• When the transmitter signal is lost, it moves the connected servo to the position you programmed. The LED on the fail-safe lights up permanently. When the
signal is restored, the servo can be controlled via the transmitter as usual.
• When battery voltage is low (approx. below 4 V) the fail-safe will move to the position you programmed as well, provided that there is still enough power left
(and the power supply is not abruptly cut off). The LED flashes differently (instead of flashing red with short light-up phases at long intervals, it now flashes red
with long light-up phases at short intervals). The servo remains in the fail-safe position, even if the receiver battery recovers slightly.
Before first use, the fail-safe has to be programmed to the right position of the throttle/brake servo.
The programmed fail-safe position must ensure that the engine is throttled back and the brake is activated.
j) Checking the range of the remote control
In order not to lose control of you model, you should before each first start or after a crash check the remote control and make sure the range is okay. For the
range check, it is sufficient to test the function of the steering servo.
Put the model on a support at the front axle so that the wheels hang freely.
Due to the wheels' good grip and the weight of the vehicle, the wheels would not directly respond to the remote control if the vehicle is on the ground. The
response is as it should be when driving.
Make sure the engine is not running when you check the range!
• Completely retract the telescopic aerial of the transmitter. Switch on the transmitter first, then the receiver.
• Step away about 50 m from your model.
• Turn the steering control wheel (channel 1) to the right. Now the wheels must turn to the right!
• Turn the steering control wheel to the left. Now the wheels must turn to the left!
• Release the steering control wheel. The wheels must go back to straight-drive position.
Never use the model with a remote control that does not function properly!
If the remote control does not work properly, first check the battery state of the transmitter and receiver batteries and make sure that no-one else is using your
frequency.
If the problem persists, proceed as described in the troubleshooting table.
