OPERATING YOUR CRAWLER
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 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 saltwater (ocean water),
brackish water (between fresh water and ocean water), or other contaminated water.
Saltwater 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 motor. Special care must be
taken to modify your driving style in wet conditions to extend the life of the
motor (details below).
Running in wet conditions
Your new LAEGENDARY GRANDO 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 GRANDO through puddles, wet grass, snow, and
through other wet conditions. Though highly water resistant, the crawler 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.
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. Confirm that your batteries can be used in wet conditions.
3. Use low gear when running in mud, deep puddles, snow, or similar situations that will
restrict the tires and put much higher loads on the motor. Although the GRANDO’s 550
motor has ample torque in second gear, using first gear in situations that require
low speed will extend motor life. Limit second-gear use to high-speed running
on dry ground.
