Before Running Your XXX-sCB
1. Break in the differentials. While holding the chassis with only the left side tires
firmly on the ground, give the car about 1/8 throttle for 30 seconds. The right
side tires should spin freely during this time. Repeat this with only the right
side tires firmly on the ground, allowing the left side tires to spin freely. Repeat
this 2–3 times.
2. Check for free suspension movement. All suspension arms and steering
components should move freely. Any binds will cause the car to handle poorly.
3. Set the ride height. Set the ride height of your truck with all components
installed so that the bottom of the chassis is 29.5mm from the ground in the
front and 24.5mm in the rear by adjusting the shock collars.
4. Set the camber. Adjusting the camber tie rod length changes the camber. Set
the front tires to have 0 degrees of camber at ride height. Set the rear tires to
have 2.5 degrees of negative camber at ride height.
5. Set the front toe-in. Adjust the steering tie rods so that when the servo is
centered on the transmitter, the front tires are both pointing straight.
6. Charge a battery pack. Always charge the battery pack as per the battery and/
or charger manufacturers’ instructions.
7. Adjust the electronic speed control. Follow the instructions to setup and adjust
the speed control for your XXX-SCB RTR .
8 Set the transmitter steering trim. Follow the instructions to set the steering
trim/subtrim so that the vehicle drives straight with no input to the steering.
9. Set the transmitter steering endpoints. Follow the instructions in the
transmitter instruction manual to set the endpoints so that the servo hits full
steering upon reaching full input from the transmitter.
Run Time
The largest factor in run time is the capacity of the battery pack. A larger mAh
rating increases the amount of run time experienced.
The condition of a battery pack is also an important factor in both run time and
speed. The battery connectors may become hot during driving. Batteries will lose
performance and capacity over time.
Driving the vehicle from a stop to full speed repeatedly will damage the batteries
and electronics over time. Sudden acceleration will also lead to shorter run times.
To Improve Run Times
• Keep your vehicle clean and well maintained.
• Allow more airflow to the ESC and Motor.
• Change the gearing to a lower ratio. A lower ratio lowers the operating
temperature of the electronics. Use a smaller pinion gear or larger spur gear to
lower the gear ratio.
• Use a battery pack with a higher mAh rating.
• Use the optimum charger to charge battery packs (Visit your local hobby dealer
for more information).
installing The Battery Pack(s)
To install the battery pack, remove the battery hold-down strap by removing the
clip from the front mounting boss. Then, while lifting the strap, pull forward in one
motion.
After you have inserted the fully charged battery pack, reinstall the battery hold-
down strap.
The battery hold-down has a flat side while the other side has strengthening ribs;
the rib side should be face down to the battery.
Insert on an angle into the rear support, and then down on the front pin and
secure it with the previously removed clip.
Batteries and Charging
The XXX-SCB RTR uses rechargeable batteries such as NiMH or LiPo. These
batteries all have special requirements to preserve performance and last.
• Read all instructions provided by the manufacturer of the batteries.
• Never allow minors to charge battery packs.
• Always check to ensure the polarity of battery connection is correct.
• Never leave batteries unattended while charging.
• Never charge a battery while it is installed in the XXX-SCB RTR .
• Do not charge any battery that appears to have any damage.
• If there are exposed wires, do not charge or use the battery until you install
shrink-wrap or replace the complete wire.
When charging NiMH or LiPo batteries, select a charger to meet your
requirements. You need a charger that is a 100–240V wall charger or one which
requires a 12V power supply. Follow the charger manufacturer’s instructions and
precautions during each use.
