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 18 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 18 for recovery.
• The model might have struck an object in the water causing driveline damage. Refer to
the Boat Retrieval section on page 18 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 or Motor Over-Temperature Detection systems have switched on.
•
Low-Voltage Detection
will reduce power output to 50% if low battery voltage is
detected. Return the boat to shore immediately to recharge the batteries. The LED on the
speed control will slowly blink red, indicating a low voltage shutdown.
•
Motor Over-Temperature Detection
will reduce power to 25% if the motor’s temperature
exceeds its normal operating range. Drive the model back to shore, the LED on the
receiver will flash red, indicating motor over-temperature. Disconnect the battery, and
allow the motor to cool. While the motor cools, inspect the model for possible causes of
overheating. These may include:
• Worn motor bearings
• Driveline binding due to insufficient lubrication or wear
• Debris wrapped around the prop
• Plugged or disconnected water-cooling lines
Full power will be restored when the motor has cooled and a battery is reconnected to
the speed control. Allowing the motor to cool without disconnecting the battery will not
restore full power. Always disconnect the battery if Motor Over-Temperature Detection
reduces the model’s power.
• If you are not sure which of the above conditions occurred,
do not operate the model.
Refer to the Boat Retrieval section on page 18 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 19).
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 Velineon VXL-6s Marine Speed Control and Velineon 540XL 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 Velineon 540XL 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 Velineon VXL-6s Marine speed control with the Velineon 540XL 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 Velineon power
system with non-Traxxas components.
Note
: The Motor Temperature Sensor may not fit onto
aftermarket motors and will not work with an aftermarket receiver.
For the best performance, we highly recommend the Spartan’s factory-installed Velineon
brushless system. It is optimized for the best performance, reliability, and ease of use in the
Spartan and fully supported by Traxxas customer service.
