Now it’s time to have some fun! This section contains instructions on
driving and making adjustments to your model. Before you go on,
here are some important precautions to keep in mind.
• Allow the model to cool for a few minutes between runs. This is
particularly important when using high capacity battery packs that
allow extended periods of running. Monitoring temperatures will
extend the lives of the batteries and motor.
• Do not continue to operate the model with low batteries or you
could lose control of it. Indications of low battery power include
slow operation, sluggish servos (slow to return to center), or ESC
shutdown due to the Cutoff Voltage. Stop immediately at the
first sign of weak batteries. When the batteries in the transmitter
become weak, the power light will begin to flash red. Stop
immediately and install new batteries.
• Do not drive the model at night, on public streets, or in large
crowds of people.
• If the model becomes stuck against an object, do not continue to run
the motor. Remove the obstruction before continuing. Do not push or
pull objects with the model.
• Because the model is controlled by radio, it is subject to radio
interference from many sources beyond your control. Since radio
interference can cause momentary losses of control, allow a safety
margin of space in all directions around the model in order to
prevent collisions.
• Use good, common sense whenever you are driving your model.
Intentionally driving in an abusive and rough manner will only result
in poor performance and broken parts. Take care of your model so
that you can enjoy it for a long time to come.
• High performance vehicles produce small vibrations which may loosen
hardware over time. Frequently check wheel nuts and other screws on
your vehicle to ensure that all hardware remains properly tightened.
About Run Time
A large factor affecting run time is the type and condition of your
batteries. The milliamp hour (mAh) rating of the batteries determines
how large their “fuel tank” is. A 5000mAh battery pack will theoretically
run twice as long as a 2500mAh sport pack. Because of the wide variation
in the types of batteries that are available and the methods with which
they can be charged, it’s impossible to give exact run times for the model.
Another major factor which affects run time is how the model is
driven. Run times may decrease when the model is driven repetitively
from a stop to top-speed and with repetitive hard acceleration.
Tips for Increasing Run Time
• Use batteries with the highest mAh rating you can purchase.
• Read and follow all maintenance and care instructions provided by
the manufacturer of your batteries and charger.
• Keep the electronic speed control cool. Make certain airflow to the
speed control is unimpeded.
• Use the correct Cutoff Voltage setting for your battery (Refer to
the included Castle Driver’s Ed Guide for instructions). Cutoff Voltage
can be off for maximum NiMH battery runtime. Never use LiPo
batteries while Cutoff Voltage is turned off.
• Lower your gear ratio. Installing a smaller pinion or larger spur gear
will lower your gear ratio, causing less power draw from the motor
and battery, and reducing overall operating temperatures.
• Maintain your model. Do not allow dirt or damaged parts to cause
binding in the drivetrain. Keep the motor clean.
mAh Ratings and Power Output
The mAh rating of the battery can effect your top speed
performance. The higher capacity battery packs experience less
voltage drop under heavy load than low mAh rated packs. The
higher voltage potential allows increased speed until the battery
begins to become discharged.
Do Not Operate your model in Wet Conditions
Your new Traxxas model features a waterproof steering servo
and receiver box, but the electronic speed control, motor,
and the model itself are not waterproof or water-resistant.
Do not operate the model in wet conditions, including wet
pavement. Do not run the model through puddles. Operating
this model on wet surfaces will reduce control and may
damage the electronics, resulting in loss of control.
The instructions that follow are for operating the model up
to its electronically-limited top speed of 50mph. Additional
registration, setup steps and precautions are required before
operating your model at its maximum, unrestricted speed.
Read, understand, and follow all the steps beginning on page
28 before unlocking your model’s full-power setting and
operating it at speeds over 50mph.
