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 Street Bike 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 compo-
nents together and switch on the remote control. Now set the steering trim to neutral position. Screw now the rudder
arm in an 90° 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. 11 and 14).
•
Attach the electronic speed controller and the receiver (see fi g. 27 and 29) 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 Street Bike cannot 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 and
secure it with the velcro straps. Finally re-mount the lower body part and secure it with the body clip.
Place, if not yet done, the eight AA-batteries into the battery box of the transmitter.
During switching on do not move the throttle trigger, so that the electronic 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 trembles 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 wa-
terproof. If you want to drive in the wet, these parts must be protected waterproof (e.g. by a ballon).

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