SAFETY PRECAUTIONS
• Because your model is controlled by radio, it is subject to radio
interference from many sources that are beyond your control.
Since radio interference can cause momentary loss of radio control,
always allow a safety margin in all directions around the boat in
order to prevent collisions.
• Do not reach underneath the rear of your model. The propeller
could spin unexpectedly. Always pick up the boat from the front
or the side.
• Because of the many dangers involved with any body of water,
Traxxas recommends that you never try to wade or swim to
retrieve the boat. The Boat Retrieval section in this manual outlines
safer, alternative methods for boat retrieval.
• Due to the high-performance nature of the electric motor, it can
become hot during use. Do not touch the motor when installing
and removing battery packs.
• Most importantly, use good, common sense when you are around
the water to avoid mishaps, such as slipping on a muddy bank.
Speed Control
Your model's electronic speed control (ESC) is an extremely
powerful electronic device capable of delivering high current. Please
closely follow these precautions to prevent damage to the speed
control or other components.
• Disconnect the Battery: Always disconnect the battery or batteries
from the speed control when not in use.
• Insulate the Wires: Always insulate exposed wiring with heat
shrink tubing to prevent short circuits.
• Transmitter on First: Switch on your transmitter first before
switching on the speed control to prevent runaways and erratic
performance.
• Don't Get Burned: The ESC and motor can become extremely hot
during use, so be careful not to touch them until they cool.
• Use the Factory-Installed Connectors: Do not change the battery
and motor connectors. Improper wiring can cause fire or damage
to the ESC. Please note that modified speed controls can be subject
to a rewiring fee when returned for service.
• No Reverse Voltage: The ESC is not protected against reverse
polarity voltage.
• No Schottky Diodes: External Schottky diodes are not compatible
with reversing speed controls. Using a Schottky diode with your
Traxxas speed control will damage the ESC and void the 30-day
warranty.
• Always adhere to the minimum
and maximum limitations of
the speed control as stated in
the specifications table in the
Owner's Manual. If your ESC
operates on two batteries,
Do not mix battery
do not mix battery types and
capacities. Use two
capacities. Use the same voltage
batteries with the
and capacity for both batteries.
Using mismatched battery packs could damage the batteries and
electronic speed control.
Batteries and Battery Charging
Your model uses rechargeable batteries that must be handled with
care for safety and long battery life. Make sure to read and follow
all instructions and precautions for charging and maintaining the
batteries. It is your responsibility to charge and care for the battery
packs properly. In addition to your battery and charger instructions,
here are some more tips to keep in mind.
• Do not charge batteries inside of an automobile. Do not charge
batteries while driving in an automobile.
• Never charge batteries on wood, cloth, carpet or on any other
flammable material.
• Do not operate the charger in a cluttered space, or place objects on
top of the charger or battery.
• If a battery gets hot to the touch during the charging process
(temperature greater than 140°F / 60°C), disconnect the battery
from the charger and discontinue charging immediately.
• Always store battery packs safely out of the reach of children and
pets.
• Do not short-circuit the battery pack. This may cause burns and
severe damage to the battery pack and create the risk of fire.
• Do not expose the charger to water or moisture.
• Do not disassemble the charger.
• Never leave batteries to charge unattended.
• Remove the battery from the model while charging.
• Always unplug the battery from the electronic speed control when
the model is not in use and when it is being stored or transported.
• Allow the battery pack to cool off between runs (before charging).
• Children should have responsible adult supervision when charging
and handling batteries.
Do not use a
6-cell 7.2V battery in
combination with a
same capacity. 7-cell battery 8.4V pack.
