OPERATING THE REMOTE CONTROL
•
Run your motorcycle never with low transmitter batteries or 7.2V Racing Pack.
•
Never forget switch off the radio after running your model, otherwise the batteries do not last long.
•
Turn on the transmitter fi rst, then the vehicle.
•
After driving fi rst turn off the vehicle, then the transmitter.
•
For optimal use fi rst check the steering and throttle trim positions:
ELECTRONIC SPEED CONTROL
•
The ESC does not need to be adjusted, because it adjusts itself automatically each time when switching on the
motorcycle.
•
Switch on the radio and move the throttle trigger to neutral.
•
Switch on the ESC.
•
The LED at the ESC fl ashes alternating in green and red. After approximately 2-3 seconds an audio signal indicates
the conclusion of the setting.
•
With correctly adjusted ESC, in neutral position the LED lits green, throttle or brake the LED shines red.
REFERENCES TO THE ARTR VERSION
The ARTR version of the MRX5 Cross Rider is pre-mounted, so only the remote control (servo and receiver) and the
electronic speed control have to be inserted.
Before the installation please read the guidances of remote control and electronic speed control!
•
First the steering servo is installed. Before you screw the rudder arm on the servo, plug the remote control com-
ponents together and switch on the remote control. Now set the steering trim to neutral position. Screw now the
rudder arm in an 27° angle on the servo (the exact adjustment takes place later with the trim knob). Now you can
switch the remote control off and unplug the servo from the receiver for easier installation (see fi g. 17).
•
Attach the electronic speed controller and the receiver (see fi g. 24) with the enclosed double-sided tape to the
chassis.
•
Before you start, check the steering and ESC trim position.
but not goes in reverse! The Cross Rider cannot drive drive backwards, just like a real motorcycle! If the electronic
speed controller goes in reverse, the centrifugal clutch in the fl ywheel can be damaged!
OPERATION
First you have to charge the racing pack with an appropriate battery charger. Please consider the safety
notes for the battery and charger! When the battery is fully charged, place it into the battery holder on the
bottom of the chassis, close the battery holder and secure it with 2 c-clips.
Place, if not yet done, the eight AA-batteries into the battery box of the transmitter and screw the antenna into
the mounting plate at the top of the transmitter. Finally push the enclosed antenna tube into the holder at the
chassis and thread the antenna cable through.
If you want to drive at a place at which remote controlled vehicles are on the way already, make sure fi rst
whether your transmitter frequency/channel is still free, in order to avoid that yours or other vehicles get out of
control. Turn on the transmitter fi rst and then the vehicle. To change the frequency, crystal-sets are available
under order-nr. 94010.50 - 94010.92. During switching on do not move the throttle trigger, so that the electro-
nic speed controller can initialize itself correctly. The speed controller is correctly adjusted, when the LED lits
green in neutral position, with throttle or brake engaged the LED lits red. Before you drive, check the correct
function of the vehicle: does it react accurately on your remote control? If not, e.g. the steering servo trem-
bles or uncontrolled throttle reaction, start driving in no case. Check whether the transmitter batteries have
enough voltage or the 7.2 V Racing Pack is fully charged and change it and/or recharge if necessary. Also
you should control the directional stability, a central position of the steering wheel at the transmitter means
the model runs straightforward. You can correct this by the trim lever above the steering wheel. Press the
lever into the desired direction until the car runs in a straight line.
Don't drive against obstacles, which the model cannot overcome, and stay on full throttle. This can destroy
the motor, electronic speed controller or the transmission!
Don't drive in wet grass or puddles, because the electronic equipment (servo, receiver and speed controller)
is not waterproof. If you want to drive in the wet, these parts must be protected waterproof (e.g. by a bal-
lon).

Attention: transmitter throttle trigger stays at neutral.
Note: program the ESC in such a way that it brakes only
