Driving Your Model - Traxxas EREVO Owner's Manual

DRIVING YOUR MODEL

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 motors..
• 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 and
sluggish servos (slow to return to center). Stop immediately at the first sign of
weak batteries. When the batteries in the transmitter become weak, the red
power light will begin to flash. 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
motors. 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 3000 mAh battery pack will theoretically run twice as long as a 1500
mAh 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.
• Use a high-quality peak-detecting charger.
• Read and follow all maintenance and care instructions provided by the
manufacturer of your batteries and charger.
• Keep the EVX-2 cool. Get plenty of airflow across the ESC heat sinks.
• Lower your gear ratio. Installing smaller pinion gears will lower your gear
ratio and cause less power draw from the motors and batteries, and reduce
overall operating temperatures. Always replace both pinion gears together.
• Maintain your model. Do not allow dirt or damaged parts to cause binding
in the drivetrain. Keep the motors 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.
RUNNING IN WET CONDITIONS
Your new Traxxas E-Revo is designed with water-resistant features to protect
the electronics in the model (receiver, servos, electronic speed control). This
gives you the freedom to have fun driving your E-Revo through puddles,
wet grass, snow, and through other wet conditions. Though highly water
resistant, the E-Revo should not be treated as though it is submersible or
totally, 100% waterproof. Water resistance applies only to the installed
electronic components. Running in wet conditions requires additional care
and maintenance for the mechanical and electrical components to prevent
corrosion of metal parts and maintain their proper function.
Precautions
• Without proper care, some parts of your model can be seriously damaged
due to contact with water. Know that additional maintenance procedures
will be required after running in wet conditions in order to maintain the
performance of your model. Do not run your model in wet conditions
if you are not willing to accept the additional care and maintenance
responsibilities.
• Not all batteries can be used in wet environments. Consult your battery
manufacturer to see if their batteries can be used in wet conditions. Do not
use LiPo batteries in wet conditions.
• The Traxxas TQi transmitter is not water resistant. Do not subject it to wet
conditions such as rain.
• Do not operate your model during a rain storm or other inclement weather
where lightning may be present.
• Do NOT allow your model to come in contact with salt water (ocean
water), brackish water (between fresh water and ocean water), or other
contaminated water. Salt water is highly conductive and highly corrosive.
Use caution if you plan to run your model on or near a beach.
• Even casual water contact can reduce the life of your motors. Special care
must be taken to modify your gearing and/or your driving style in wet
conditions to extend the life of the motors (details below).
Before Running Your Vehicle in Wet Conditions
1. Consult the section "After Running Your Vehicle in Wet Conditions" before
proceeding. Make sure you understand the additional maintenance
required with wet running.
2. The wheels have small holes molded in to allow air to enter and exit the
tire during normal running. Water will enter these holes and get trapped
inside the tires if holes are not cut in the tires. Cut two small holes (4mm or
3/16" diameter) in each tire. Each hole should be near the tire centerline,
180 degrees apart.
3. Confirm that the receiver box O-ring and cover are installed correctly and
secure. Make sure the screws are tight and the blue O-ring is not visible
protruding from the edge of the cover.
