Caution: Risk of explosion
if battery is replaced by an
incorrect type. Dispose of
used batteries according to
the instructions.
1. Use only four(4) AA alkaline batteries in your ATX100 transmitter.
2. Do not dispose of the battery in a fire as it may explode. Check with local codes for
possible special disposal instructions.
3. Do not open or mutilate the battery. Released electrolyte is corrosive and may cause
damage to the eyes and skin. It may be toxic if swallowed.
4. Exercise care in handling batteries in order not to short the battery with conducting
materials such as rings, bracelets and keys. The battery or conduction material may overheat and cause burns.

this device may not cause harmful interference, and
(2) this device must accept any interference received;
including interference that may cause undesired

Temper a t u r e Pro t e c ti o n
If the ESC temperature exceeds 80 degrees
Celsius for 5 seconds or longer, the ESC will
enter temperature protection mode and the
status LED will blink quickly.
Once the ESC has cooled down it will resume
normal operation.
We design all ARRMA cars to be fun and quick to get used to.
However, it is important to be comfortable with the handling
before exploring the upper reaches of your car's performance.
Post-Drive Checks
i
For the first run we recommend taking your kit to an open, flat
area (such as a park) ensuring you are away from potential
hazards, people or animals.
Start by simply driving round in a large loop, slowly building
up speed to get used to the handling. Alter the size of the loop
and your speed. Watch out for the rear-end of the car breaking
loose. If the car does slide try to counter-steer into the skid and
accelerate out or let-off the throttle and let it come to a stop.
To take a corner you need to slow down before the corner, hold
your speed through the curve and, once you see an exit line,
accelerate out of the corner.
Once you have practiced the basic driving techniques and you
are comfortable with the performance of the car you can start to
open-up the full performance potential of your car.

it can also affect the chassis balance

The steering arm links are the connection between the front hubs and

front toe-in/-out.
Adjusting the toe can create either toe-in, which is where the wheels point
inwards towards a centreline in front of the vehicle, or toe-out where the
wheels point towards a centreline behind the vehicle. The effect of these
adjustments is below:

Drivetrain Tuning
Gear Chart
Your ARRMA kit has one gear ratio and this can be altered by changing the pinion or spur gear in the
transmission. The standard gearing of your kit is designed to give the best compromise between speed and acceleration. Increasing the
top speed will reduce acceleration and vice versa. Too low or high a gear will put strain on the motor/ESC, and potentially damage them.
The numbers shown in chart is the number of times the spur gear is larger than the pinion, or the ‘gear ratio’. Essentially this is number
of rotations the motor/pinion gear has to rotate the larger spur gear once. The lower the ‘gear ratio’ the greater the potential top speed,
the higher the ‘gear ratio’ the greater the potential acceleration.
Upgraded motors/ESCs and non-standard wheels may require different gear ratios. Try to find the best balance between speed/
acceleration and handling/performance. For help selecting the correct gear ratio for your upgrades visit the GO FOR IT forums at
GOFORIT-RC.com.

Differential Tuning
When turning a corner the inside wheel travels
a shorter distance than the outside wheel. A
differential allows the wheels to turn at different
speeds and take a corner more quickly.
Without a differential, on a high grip surface, the
inside wheel will lose traction and cause you to
spin-out. This effect is less noticeable on loose
surfaces, however a well setup differential will
make the car easier to drive and give more
predictable handling at speed.
The differential is filled with silicone oil and the
thickness of this alters the operation of the
differential unit. As standard, your differential
is designed to provide safe, fun handling for advice on which oil to use please visit the

Fit new electric motor (if required), fit pinion gear to
motor then set gear mesh (page 13). Replace spur gear
cover and rear wheel.
Oil WeightCharacteristic
Thinner (Lower CST)Looser differential action
Less stable under braking (into corners)
Faster steering into corner
More steering in corner
Greater chance of oversteer
More chance of wheelspin
Less forward drive out of corner (in low grip conditions)
Generally better for low traction surfaces
Thicker (Higher CST)Tighter differential action
More stable braking (into corner)
Slower steering into corner
Less steering in corner
Greater chance of understeer
Less chance of wheelspin
More forward drive out of corner
Generally better for high traction surfaces

driver, remove roof.
Steering Maintenance
2mm Hex Driver
If you want to replace or upgrade the steering servo, ESC
(electronic speed controller) or re-bind the transmitter, you
will need to access the receiver.
2
Remove four bolts securing receiver box lid with 2mm
hex key, remove lid. Reinstallation is the reverse the
removal process.

steering feels loose it may mean you have to
adjust the servo saver. To do this you will have
to get access to the steering mechanism.
