13. Troubleshooting
This model was built using the latest technology. However, faults and malfunction may still occur. The following section
shows you how to troubleshoot potential faults. Ensure that you also read the remote control instructions included
with the product.
The model does not respond or does not respond correctly
• In the case of 2.4 GHz remote control systems, the receiver must be connected to the remote control. This process
is known as "pairing". The manufacturer pairs the remote control with the receiver before the vehicle is shipped.
However, you can also pair the remote control yourself. To do this, follow the enclosed operating instructions for
the remote control.
• Is the vehicle battery or the remote control batteries empty? If so, replace the vehicle battery or remote control
batteries.
• Did you switch on the remote control before switching on the speed controller? For safety reasons, the speed
controller does not function if this is done in the reverse order.
• Is the vehicle battery connected to the speed controller? Check the connection to see if it is dirty or rusted.
•
Is the vehicle too far away? The range should be at least 50 m when the vehicle battery and the remote control
batteries are full. However, this can be reduced by the ambient conditions, such as interference on the transmission
frequency or proximity to other transmitters (including Wi-Fi/Bluetooth
®
devices that use a transmission frequency
of 2.4 GHz), metal objects and buildings.
The position of the remote control and receiver aerials relative to one other also has a significant impact on the
range. For best results, the remote control and receiver aerial should be vertical (i.e. parallel to each other). Pointing
the remote control aerial at the vehicle significantly reduces the range.
• Check the correct position of the speed controller plug and steering servo on the receiver. If the plugs have been
rotated 180°, the speed controller and steering servo will not work.
If the connectors for the speed controller and steering servo are connected the wrong way round, the throttle/brake
servo will control the steering servo (and vice versa).
The vehicle doesn’t stop when the throttle/brake lever is released
• Correct the throttle trim on the remote control (set the neutral position).
The vehicle travels slowly or the steering servo does not respond properly to remote control commands; the
range between the remote control and the vehicle is very short
• The vehicle battery is nearly empty.
The receiver and the steering servo are powered by the BEC in the speed controller. As a result, the receiver will not
function properly when the battery is nearly empty. Replace the vehicle battery with a fully charged battery (before
changing the battery, wait for at least 5 - 10 minutes for the motor and speed controller to cool down).
•
Check the batteries in the remote control.
