15. Fail-Safe Function

Your remote control receiver offers the option of taking the throttle servo or the electronic speed controller to a certain 

position or to the stop function if no correct remote control signal is received any longer in case of an interference. 
If the idle position (central position of the operating lever for driving) was selected as a fail safe position, the vehicle 

comes to a halt automatically if the radio transmission is interfered with or the model drives out of the remote control‘s 

range. 
You can also select any brake position (e.g. 50% brake effect) as the fail safe position (sensible e.g. for a combustion 

vehicle). In this case, fix the operating lever for driving in the desired position with a rubber ring when setting the fail 

safe function.

In order perform the fail safe settings, proceed as follows:

• 

Take the operating lever for driving to the desired position.

•  First, switch on the transmitter and then the receiver.
•  Right after that, push and hold the fail-safe button at the re-

ceiver (17).

•  The receiver LED (16) on the receiver starts to flash after ap-

prox. 3 seconds.

•  When the LED flashes, release the button.
• 

When the LED is lit again permanently, the fail safe position 

is stored.

•  The saved fail-safe position remains saved even after switch-

ing the receiver off and on again.

Then perform a function test; proceed as follows:

• 

When using the throttle servo, accelerate a little with the combustion engine out and then switch off the transmitter. 

The throttle servo then has to go into the fail safe position immediately. 

•  For electronic models with an electronic speed controller, support the vehicle so that the wheels can turn freely for 

the test. Then take the vehicle into operation as usual. Move the operating lever for the driving function towards the 

handle so that the motor starts up and the wheels turn.
If you switch off the transmitter now, the motor must stop if the middle position of the operating lever for the driving 

function was saved as the fail-safe position first.
