TROUBLESHOOTING

The following section addresses some very basic questions you may have
about your model. If you can't find a solution here, you may call Traxxas
Customer Service at 1-888-TRAXXAS (U.S. residents only).
If the model stopped suddenly:
• Release the transmitter trigger immediately. Do not try and "force" the model
to move. Refer to the Boat Retrieval section on page 19 for recovery.
If there is an inconsistent reduction in power:
• There could be something wound around the prop (such as trash, algae
or fishing line). If you continue to drive your model with a bound prop,
the high load could create excessive heat and seriously damage the
batteries, speed control, or motor. Refer to the Boat Retrieval section on page
19 for recovery.
• The model might have struck an object in the water causing driveline
damage. Refer to the Boat Retrieval section on page 19 for recovery.
If there is an immediate reduction in power:
If the model's power output is reduced suddenly, it is likely because the Low-
Voltage Detection system has switched on.
• Low-Voltage Detection will reduce power output to 25%. This allows
sufficient power to return the model to shore. To prevent over-discharging
your LiPo battery after Low-Voltage Detection limits power, return your
model to shore and disconnect the LiPo pack(s) from the model immediately.
Low-Voltage Detection allows operation with limited power for returning to
shore ONLY. Operating the model longer than necessary to return to shore
may cause over-discharging and permanent damage to LiPo batteries. Always
return your model to shore and disconnect the batteries from your model as
soon as Low-Voltage Detection limits power. The LED on the speed control
will slowly blink red, indicating a low voltage shutdown. The VXL-6s will stay
in the reduced power mode until a fully charged battery is connected.
• If you are not sure if the above condition occurred, do not operate the model.
Refer to the Boat Retrieval section on page 19 for recovery.
INCREASING PERFORMANCE
While your model is a great performer out of the box, there are
steps you can take to increase the speed of the boat.
1. Adjust the trim tab angle correctly. The trim tab angle should be trimmed
down just enough to keep the bow of the boat from porpoising (bouncing
up and down) in the current water conditions. If the trim tabs are set too low,
then it pushes the bow lower and increases drag in the water (see page 20).
2. Maintain your boat. Your model will be faster if it is kept clean and in good
working order. Replace the prop if it gets nicked or damaged. Keep the
motor clean and oiled. Make sure the drivetrain turns freely with no binding
or excess friction.
3. Use the best batteries and charger you can afford. Low-cost, low-capacity
battery packs will limit the performance of your model. Likewise, a low-
cost charger may not allow your batteries to achieve their peak power
and capacity. For best performance, use battery packs rated for 3000mAh
or higher. Traxxas Power Cell NiMH packs are specially constructed for
durability and performance in high-power Traxxas models. The Traxxas
EZ-Peak charger (#2930) is recommended for use with Power Cell NiMH
batteries. If you plan to purchase LiPo batteries, consult your local hobby
dealer or call 1-888-TRAXXAS for advice on purchasing the appropriate LiPo
batteries and LiPo charger for your model.
Using Aftermarket Props
Spartan's included prop has been carefully designed for maximum
performance and durability. It does not require sharpening or balancing
and is inexpensive to replace if damaged. If you do wish to experiment with
aftermarket props, Traxxas recommends using props that range in diameter
from 38-42mm, with a pitch-to-diameter ratio of about 1.4:1 (To determine this
ratio, divide pitch by diameter. For example, the Spartan's stock prop is 42mm
in diameter with a pitch of 59mm. 59 ÷ 42 = 1.404). Avoid props larger than
42mm, as these will increase amp draw and reduce performance.
Using Aftermarket Motors and Speed Controls
Important:
The VXL-6s Marine Speed Control and 540XL Brushless Motor have
been optimized to work together for the absolute best performance, reliability,
and efficiency. Using an aftermarket motor with the VXL-6s speed control, or
an aftermarket speed control with the 540XL Brushless Motor, may result in
damage to the Traxxas components and/or aftermarket components. Damage
incurred by mixing Traxxas and aftermarket components will not be covered by
any expressed or implied warranty. Only use the VXL-6s Marine speed control
with the 540XL Brushless Motor.
If you wish to outfit your model with an aftermarket brushless system, you
must replace both the motor and the speed control. Traxxas recommends a
motor with a kV rating of 1600-1800 kV. Make certain the speed control you
choose is compatible with your motor, is designed for marine use, and is
waterproof. Water cooling is highly recommended. Additional silicone tubing
may be required to properly plumb your speed control's water-cooling system.
The Traxxas water-cooling motor jacket is not compatible with all motors.
Install an appropriate water-cooling system for the motor you choose. Traxxas
is not responsible for damage to your model or the components you install in
the model if you replace the power system with non-Traxxas components.
For the best performance, we highly recommend the Spartan's factory-installed
brushless system. It is optimized for the best performance, reliability, and ease of
use in the Spartan and fully supported by Traxxas customer service.
