THE REMOTE CONTROL SYSTEM
Here you get an overview of the remote control system of the Roadfighter Buggy and its various functions and settings.
Before the first trip you should be sure all of these functions and settings have read and understood.
Place 8 AA batteries in the battery compartment of the transmitter. Pay attention to the polarity! Now push the antenna
wire of the receiver through the antenna pipe and then put this into the mount at the chassis.
REQUIRES
To operate your new Roadfighter Buggy you will need the following:
8 alkaline AA batteries e.g. No. 3426, or 8 AA battery cells e.g. No. 3621 for transmitter and a suitable charger like•
the Graupner Ultramat series
NiMH battery e.g. No. 98900 GM Power-Pack 7.2V/3600 mAh and a suitable charger like No. 6464 Minilader 3 or•
Ultramat 8, No. 6411
REMOTE CONTROL (TRANSMITTER)
1. ON / OFF switch: Turns the power on/off
2. Steering wheel: Controls direction (left/right) of the model
3. Steering trim: Adjusts the “hands off” direction of the model
4. EPA steering: to set the maximum steering angle
5. Throttle Trigger: Controls speed (forward/brake/reverse) of the model
6. Throttle Trim: Adjusts the motor speed to stop at neutral
7. Control light: indicates adequate battery power
8. Antenna: Transmits signal to the model
The remote control system of the Roadfighter Buggy is optimally adjusted by the factory. Nevertheless you should read
the following chapter, maybe slight adjustments on the remote control should be necessary. For further information to
the remote control system please refer to the enclosed XG-6i 2.0 FHSS manual.

OPERATING THE REMOTE CONTROL
• Run your Roadfighter Buggy never with low transmitter or receiver batteries.
• Never forget switch off the radio after running your vehicle, otherwise the batteries do not last long.
• Turn on the transmitter first, then the vehicle.
• After driving first turn off the vehicle, then the transmitter.
• For optimal use first check the steering and throttle trim positions.
Before the first trip you should be sure all of these functions and settings have read and understood.•
STEERING TRIM
The vehicle should go straight without turning the steering wheel. If not, press the Steering Trim knob above the steering
wheel in the direction needed for the vehicle to go straight.
THROTTLE/BRAKE TRIM
Normally you do not need to adjust anything here, because the neutral point is stored automatically during the ESC
setting. But if the motor turns a little in neutral position, you can correct this with the trim lever below the steering wheel.
Press the lever in the appropriate direction until the motor has stopped and no longer beeps.
ADJUSTING THE STEERING ANGLE
The maximum steering angle can be adjusted with the two buttons on the pistol grip. Pressing the upper button uincre-
ases the the steering angle, by pressing the lower switch the angle is decreased.
Position 1: less control, the vehicle is less sensitive to steering commands of the steering wheel and is therefore easier
to drive - for slippery surfaces.
Position 2: more steering, the vehicle can run tighter turns, but because this it is to drive a little harder - for non-slip
surfaces or when driving on small places.
Caution: make sure that the steering arms (90166.34) do not touch on the C-hubs (90166.35), otherwise the servo
gears will be damaged!
With the servo end point adjustment (EPA), the steering angle can be adjusted separately for both sides, this may be
necessary if the steering angle is different on both sides even after correct steering trim. Read the corresponding section
of the remote control instructions!

CHECKLIST BEFORE YOU START
Check all screws on permanent seat.•
Check all the moving parts to work without binding.•
Check the batteries in the remote control.•
LET THE FUN BEGIN
The Roadfighter Buggy is equipped with an adjustable slipper clutch. With this the acceleration of the car can be adap-
ted to each surface. You can adjust the maximum torque of the motor, the slipper also protects the drive train against
mechanical overloading. The slipper clutch is optimally adjusted by the factory. For slippery surfaces it can be opened
somewhat, therefore remove the cap at the gear cover 90166.9 first. Now loose the M3 nut a little, just until optimal ac-
celeration without wheelspin is reached. In addition push the vehicle backwards and then pull the trigger to full throttle.
There should be no or only very little wheelspin. For a very grippy surface (e.g. asphalt) you can tighten the nut some-
what to improve acceleration. Now install the cap of the gear cover again. Please consider: Tighten the adjusting nut
never completely, the slipper should always be in function, in order to protect the transmission and the drive train.
First, charge the drive battery with a suitable charger. You should also read the instructions of the charger and the safety
precautions listed before charging!. Insert the battery as shown in the figures below.
First switch on the transmitter and second then the vehicle (the switch is located at the rear above the motor). 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 red LED is off in neutral position, with throttle or brake engaged the
LED lits. Consider that the speed controller does not go from braking directly into reverse, you must release the throttle
trigger and then go to reverse again.
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 car battery is fully charged and change it and/or recharge if necessary.
The run time depends on the surface. In high grass the run time is naturally shorter than on the flat road. When the bat-
tery dumps, first the car runs slower, then the speed controller completely switches off and the vehicle stops.
After driving take the battery out of the vehicle, otherwise uncontrolled starting of the motor may damage the speed
controller or the batteries.
Don‘t drive against obstacles, which the model cannot overcome, and stay on full throttle. This can destroy the engine,
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).
