Traxxas BLAST User manual

OPERATING INSTRUCTIONS
MODEL 3810
Form 3810OPINST Rev 080208 KC1114

Introduction
Thank you for purchasing a Traxxas Blast high-performance
racing boat. This manual contains the instructions you’ll need to
operate and maintain your new Blast. Look over the manual and
examine the Blast carefully before running it. If for some reason
you think the Blast is not what you wanted, then do not continue
any further. Your hobby dealer absolutely cannot accept a Blast for
return or exchange after it has been run.
Please read all of the operating instructions and precautions before
attempting to drive your new Blast. These instructions are written
with the assumption that this is your first radio controlled model.
Even if you are an experienced R/C enthusiast, it is important for
you to read and follow the procedures in this manual. Pay special
attention to the mechanical and safety precautions outlined in
this manual.
If you have any questions about your new model, then call Traxxas’
technical support line at 1-888-TRAXXAS (1-888-872-9927 U.S.A.
residents only. Outside the U.S. call 972-265-8000). Technical
support is available Monday through Friday, from 8:30am to
9:00pm central time. We hope that you will enjoy your Blast for
many hours to come.
Personal Safety Precautions
If the precautions are followed, and your Blast is operated sensibly
and with care at all times, it is exciting, safe and fun for you
and your spectators. Failure to operate your Blast in a safe and
responsible manner could result in property damage and injury.
Please make sure to follow the instructions and adhere to the
precautions.
The Blast is not intended for use by children without a responsible
adult supervising. Every precaution outlined in this manual should
be followed to help ensure safe operation. Traxxas is not liable for
any loss or damages, whether direct, indirect, special, incidental,
or consequential, arising from the use, misuse or abuse of this
product including any chemical or accessory required to operate it.
• Do not drive the Blast at night.
• Never, under any circumstances, operate the Blast in any water
where people are swimming or wading. The Blast is very fast
and could cause injury if it should collide with anyone.
• Because the Blast 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 the Blast, 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. Page 5 of this manual outlines safer methods
for boat retrieval.
• Due to the high-performance nature of the Stinger 20-turn
electric motor, it will become extremely hot during use. Do not
touch the motor when installing and removing battery packs.
• Most importantly, use good common sense when you are near
water to avoid mishaps such as slipping on a muddy bank. Always
observe water safety rules and regulations.
Required Equipment
To operate the Blast, you will need the following equipment, all of
it should be available from your hobby shop.
1. “AA” size batteries for your transmitter(8)
2. 7.2V, 6-cell rechargeable battery pack
3. Charger for the battery pack
Where to Run
Select a body of water (must be at least 10-inches deep) which is
calm and free of debris, tree stumps, moss, etc. Also, find a clean,
stable area of shoreline to launch from. Be aware that some ponds
restrict the use of model boats. Always choose a launch site which
is downwind so that the wind and waves will drift the boat back to
you if it should ever flip. Do not run the Blast in salt water.
Radio System Terminology
Please take a moment to familiarize yourself with these radio system terms.
Channel - The 27 MHz frequency band is divided into 6 channels so
that up to six models can be operated simultaneously. Each channel
Is referred to by its flag color and channel number, as shown below.
Clearing Your Frequency - A routine, verbal check to make sure
nobody else in your area is operating on the same channel. Always
clear your frequency by calling out your channel number before
operating your model. Wait or move to another area if your channel
is already being used.
Crystal (X-tal) - The plug-in device that determines which channel
the radio system will operate on. For each channel, there are two
crystals, one for the receiver and one for the transmitter. Of those
two crystals, the one marked with the lower number (.455 MHz
lower) must be inserted into the receiver.
Frequency Band - The radio frequency used by the transmitter to
send signals to your Blast. All Traxxas RTR models operate on a 27
MHz frequency band.
Neutral Position - The standing position that the servos seek when
the transmitter controls are at the neutral setting.
NiCad - Abbreviation for nickel-cadmium. The original rechargeable
hobby pack, NiCad batteries have very high current handling, high
capacity, and can last up to 1000 charging cycles. Good charging
procedures are required to reduce the possibility of developing a
“memory” effect and shortened run times.
NiMH - Abbreviation for nickel-metal hydride. Rechargeable NiMH
batteries offer high current handling, and much greater resistance
to the “memory” effect. NiMH batteries generally allow higher
capacity than NiCad batteries. They can last up to 500 charge cycles.
A peak charger designed for NiMH batteries is required for
optimal performance.
Receiver - The radio unit inside your Blast that receives signals from
the transmitter and relays them to the servos.
Servos - Small motor units in your Blast that operate the throttle and
steering mechanisms.
Channel Frequency Band Flag Color Traxxas Part No.

Transmitter - The hand-held radio unit that sends throttle and
steering instructions to your Blast.
Trim - The fine-tuning adjustment of the neutral position of the
servos, made by turning the throttle and steering trim knobs on the
face of the transmitter.
Electronic Speed Control - Controls the speed of the boat. Fully
digital-proportional for precise throttle control at all speeds.
Preparing to Run
Opening the Hatch
The top hatch is held secure with a rubber band. To open the
top hatch, pull it up and rotate it. This will provide access to the
battery compartment and on/off switch. For full access to the radio
compartment, unhook the rubber band from the top hatch.
Installing Transmitter Batteries
Your transmitter uses 8 “AA” size batteries. They should be
alkaline dry cells, or NiCad rechargeable batteries. The battery
compartment is located in the back of the transmitter. To remove
the battery door, push down and slide in the direction of the
arrow. Be sure that the switch is turned off before installing the
batteries. Insert the batteries into the battery compartment
making careful note of the polarity. Now, slide the battery door
back in place.
Setting Up the Antenna
You must install the antenna mast (tube) before you operate your
Blast. You’ll find the plastic antenna tube and tip in the bag with your
manuals and documentation.
1. Locate the black antenna wire that exits the
receiver cover.
2. Pull the wire straight with your fingers and
then insert the end of the wire into one end
of the antenna tube. Push the wire all the way
through the antenna tube.
3. Pull the remaining wire through the antenna
tube, and then insert the base of the antenna
tube into the molded post on top of the
receiver cover.
4. Fold the remaining antenna wire over the top
of the tube and secure it with the antenna tip.
5. On the transmitter, always fully extend the
telescoping antenna when running your Blast.
Make a habit of holding the transmitter so that
the antenna points straight up.
Installing the Battery Pack
The battery installs in the bow (front) of the boat. Remove the
foam block and slide the battery pack into the battery tray. Slide
the foam block back into place to secure the battery. The Blast is
not designed to use 7-cell (8.4 volt) battery packs.
The Traxxas High-Current Connector
Your model is equipped with the Traxxas
High-Current Connector. Standard
connectors restrict current flow and are not
capable of delivering the power needed
to maximize the output of the ESC. The
Traxxas connector’s gold-plated terminals
have large contact surfaces to ensure positive current flow with
the least amount of resistance. Secure, long-lasting, and easy to
grip, the Traxxas connector is engineered to extract all the power
your battery has to give.
To run this model, your batteries must be equipped with Traxxas
High-Current Connectors. Batteries can either be purchased new
with Traxxas connectors installed or Traxxas connectors can be
purchased to install on battery packs you already own.
The typical Molex style connector is inadequate for
use in your model. It creates resistance that becomes
a bottleneck to current flow. If your battery pack
is equipped with a Molex connector, it must be
replaced with a Traxxas High-Current Connector to
mate with the electronic speed control.
Transmitter Controls
Throttle Neutral Adjust - A switch (located
to the right of the throttle stick (channel
2)) that controls the amount of desired
forward and reverse travel of the throttle
trigger. It should stay in the down position
as shown in the drawing (right). If you
change this adjustment, your transmitter
throttle trim will have to be reset.
Throttle Trim/Steering - Adjust the throttle trim control so
that the motor in the Blast does not run after the battery pack is
plugged in. Adjust the steering trim so that the Blast will drive
straight without veering to the left or right.
Radio System Adjustment
Your radio system was pre-adjusted before it left the factory
however, the adjustment should be checked prior to running the
Blast. These instructions are for Traxxas radio systems only. If you
installed your own radio, refer to your radio system’s instructions.
• Each time you prepare to run your Blast, you must clear your
frequency to be sure no one else in the area is using the same
channel as you.
• There are six possible channels, numbered 1 through 6. Each is
represented by a color. Look at the crystal plugged into the back
of your transmitter to determine which channel your boat is assigned to.
• Always turn your transmitter on first and off last. This procedure will
help to prevent your Blast from receiving stray signals from another
transmitter, or other source, and running out of control.
• Turn “on” the switch on your transmitter. Turn “on” the switch
inside the boat. The steering servo should jump and move to
its idle (neutral) position. Keep fingers and obstacles away from
the propeller.
• Operate the steering control on
the transmitter (channel 1).
Check for rapid operation of the
steering servo and that none of
the steering mechanism is loose
or binding. If the servo operates
slowly, check for weak batteries.
Adjust the “steering trim” control
on the transmitter to adjust the
servo so that the outdrive is
pointing straight out from the
back of the boat. Also, check to
be sure that the outdrive does not turn more in one direction
than in the other. If you cannot align the outdrive, refer to the
section “Centering Your Servos.”
• Operate the throttle trigger on the transmitter to ensure that the
throttle is operating properly. If the propeller is spinning when you
plug in the battery, or it doesn’t seem to reach full speed, then you
may have to adjust the transmitter trim settings.
• The radio system should be range-tested before each session of
running. With the radio system on, have a friend carry the boat
away from you a distance equal to the maximum range you plan
SET THROTTLE NEUTRAL
ADJUSTMENT TO THE
DOWN POSITION.

to operate the the Blast. At distance, once again test for complete
radio control. Never attempt to run the Blast if the radio appears
to be malfunctioning in any way.
Centering your Servos
Whenever your radio system has been removed for service or
cleaning, the steering servo must be re-centered prior to installing
the radio system in the model. If the radio system is already
installed in the boat, disconnect the servo horn from the servo.
Connect the steering servo to channel 1 on your receiver and the
electronic speed control to channel 2. The white wire on the servo
cable is positioned towards the crystal. Nothing connects to the
“batt” terminal on the receiver.
Place fresh “AA” batteries in the transmitter and turn the power
switch on. Slide the throttle and steering trim adjustments to the
center position. Connect a fresh 7.2V battery pack to the electronic
speed control and turn the power switch to the ON position. The
servo will automatically jump to its center position.
Turn off the electronic speed control switch followed by the
transmitter. The servo is now ready to be installed. Be careful not to
move the servo shaft when installing the steering linkage.
Piloting the Blast
Your new Traxxas Blast is designed with water-resistant features
to protect the electronics in the model (receiver, servo, electronic
speed control). This gives you the freedom to have fun piloting your
Blast. Though highly water resistant, the Blast should not be treated
as though it is submersible or totally, 100% waterproof. Water
resistance applies only to the installed electronic components.
Additional care and maintenance is required when water contacts
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 order to
maintain the performance of your model.
• 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 (Note: the
Nautica ESC is not LiPo compatible).
• The Traxxas transmitter is not water resistant.
• 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.
• Select a body of water (at least 10 inches deep) which is clear of
moss and grass. Do not drive the Blast in rough, choppy water or
in high wind (more than 15 mph). These conditions could cause
your Blast to flip over.
• The Blast’s steering is very sensitive, a slight input on the steering
control will have a large effect on the boat. When the boat is in
open water, adjust the steering trim on the transmitter until the
boat travels in a straight line on its own. (Note: The Blast will only
travel in a straight line on its own when it is heading straight into
or away from the wind. Crosswinds will require constant steering
input to maintain a straight course.)
• To prevent spin outs, avoid sharp turns at high speed.
• Always be ready to reduce the throttle if the Blast appears to be
unstable or “chine walking” (rocking violently from side-to-side).
Always reduce the throttle when turning, especially in rough
water. Jumping the Blast or towing anything with it should not
be attempted.
• Return the Blast to shore at the first sign of weak batteries (Blast
will begin to slow and the controls will become sluggish).
Cavitation
If the Blast is running at full throttle but is only barely moving
forward then the propeller is cavitating. Try advancing the throttle
slowly to get the Blast on plane. If you are having trouble with
cavitation, check the propeller for nicks or tangled debris. The
Blast’s propeller is specially designed for its application, therefore,
it’s very sensitive to any changes or modifications. If the prop is
damaged it should be replaced.
Before Running Your Blast
1. Consult the section “After Running Your Blast” before
proceeding. Make sure you understand the maintenance
required .
2. Confirm that the RX 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.
3. Confirm that your batteries can be used in wet conditions.
4. Normally, very
little water will
accumulate inside
the boat. Empty
any standing water
out of the boat
between runs. Drill
a small hole (1/16 in.)
in the front of the
boat to drain the water. Do not drain the water out of the back
of the boat (near the radio system).
5. Check the wiring for any frayed wires or loose connections.
6. Check the tightness of the set screws in the collars on the
steering linkages and in the universal joint yokes (connecting
the outdrive to the driveshaft and the driveshaft to the motor).
Threadlocking compound can be applied to these screws to
prevent them from loosening.
7. Check the mounting of the receiver and servos.
8. Check the rubber driveshaft seal for cuts and tears. Do not
attempt to run the Blast if this seal is damaged.
9. Check the tightness of the propeller. Hold the u-joint and turn
the propeller clockwise until it’s fingertight. Visually inspect the
prop for nicks, dings and warpage. Replace if damaged.
10. Check the operation of the radio system, especially the
condition of the batteries.
11. Visually inspect the hull for any cracks, damage or
possible leaks.
12. Check for deterioration of the rubber band which holds the
top hatch.
After Running Your Blast
1. Spray all the bearings, drivetrain, and fasteners with WD-40® or
similar water displacing light oil.
2. Let the boat stand or blow it off with compressed air.
Removing the hatch and placing the boat in a warm sunny
spot will aid drying.
3. As a precautionary step, remove the sealed receiver box

cover. While unlikely, humidity or tiny amounts of moisture or
condensation may enter the receiver box during running. This
can cause long-term problems with the sensitive electronics in
the receiver. Removing the receiver box cover during storage
allows the air inside to dry. This step can improve the long-
term reliability of the receiver. It is not necessary to remove the
receiver or unplug any of the wires.
Receiver Box:
Maintaining a Watertight Seal
Removing and Installing Radio Gear
The unique design of the receiver box allows the removal and
installation of the receiver without losing the ability to maintain a
watertight seal in the box. The patent-pending wire clamp feature
gives you the ability to also install aftermarket radio systems and
maintain the watertight features of the receiver box.
Removing the Receiver
1. To remove the cover, remove the two 3x10mm button-head
cap screws.
2. To remove the receiver from the box simply lift it out and set
to the side. The antenna wire is still inside the clamp area and
cannot be removed yet.
3. Remove the wire clamp by removing the two 2.5x8mm
cap screws.
4. Unplug the servo cables from the receiver and remove
the receiver.
Receiver Installation
1. Always install the wires into the RX box before installing
the receiver.
2. Install the antenna wire
and the servo cables into
the receiver box.
3. Arrange the wires neatly
using the wire guides in
the receiver box. The
excess wire will be
bundled inside the
receiver box. Label which
wire is for which channel.
4. Apply small bead of silicone grease
(Traxxas part #1647) to the wire clamp.
5. Install the wire clamp and tighten the
two 2.5x8mm cap screws securely.
6. Install the receiver into
the box and plug the wires
into receiver.
7. Make sure the O-ring is properly
seated into the groove in the
receiver box so that the cover
will not pinch it or damage it in
any way.
8. Install the cover and tighten the
two 3x10mm button-head cap
screws securely.
9. Inspect the cover to make sure that the O-ring seal is not visible.
Tuning Adjustments
Adjusting the Trim Angle
The outdrive strut on the Blast will allow you to adjust the trim
angle of the propeller. The trim angle changes how high the bow
of the boat rides out of the water. Setting the trim angle correctly
will provide the maximum speed and efficiency from the Blast.
As the outdrive is trimmed up, the bow (front) of the boat will ride
higher causing the boat to run slightly faster, however, it will be
more unstable in the wind. Do not trim the outdrive up on windy
days or when running in choppy water. If the trim is set to high,
the bow will bounce up and down (“porpoise”), and the prop may
begin to cavitate. As the outdrive is trimmed down, the bow of
the boat is lowered thus increasing the wetted surface of the boat.
This will slow the Blast slightly but, stability and control will be
improved. Experiment with this adjustment to find out what works
best for your particular conditions.
Adjusting the Outdrive Shaft End Play
There should be a slight amount of shaft end play in the outdrive
housing. To adjust the end play loosen the set screw on the U-joint
yoke (see drawing). Pull the propeller shaft until there is no more
than 1mm of distance at “arrow 2” in the drawing. Retighten the
set screw.
Boat Retrieval
If the Blast accidentally flips over and fills with water, it is equipped
with foam flotation to help prevent it from sinking. Traxxas does
not recommend ever trying to swim or wade to retrieve a boat. If
you have chosen your launch sight carefully (downwind), the Blast
will probably drift back to you on its own.
If there is no wind, you will need a tennis ball and a length of string.
Tie the tennis ball securely to one end of the string and then throw
the ball over the drifting boat. Pull the ball in and try to entangle
the boat in the string. Pull the boat back slowly to shore. If only the
bow of the boat remains visible, try using a fishing lure with many
hooks and a fishing pole. Try to snag the lip of the upper deck or
drive mechanism with the hooks.
Maintenance
• Keep the Blast clean of accumulated dirt and oil.
• Re-oil the motor bushings before each day of running. Use an oil
made for electric motors such as 3-in-1 Oil.
™
• Periodically re-oil the bushing in the outdrive housing and
the driveshaft tube. The oil-hole for driveshaft tube is located
underneath the sealed receiver box.
Storage
Drain all water out of the Blast and thoroughly dry it before you
store it. Store the Blast with the hatch cover removed so that any
remaining moisture will have an opportunity to evaporate.
Painting the Hull
If you wish to paint your hull some other color than the factory
white, choose your paint with caution. Only use paint made for
plastic models (available from your hobby dealer). Test the paint on
an inconspicuous and non-critical area before painting the entire
boat. The paint on the bottom must be smooth to prevent a loss
of performance.

consider removing the accessories prior to shipment. In case
of loss during transit from Traxxas to you, Traxxas can only be
responsible for the replacement cost of a new stock model.
• Ship your package insured for the new replacement value of the
product. Traxxas cannot be responsible for items lost in transit
from you to Traxxas.
• Package the product in the most efficient size box possible.
Loose product in oversize boxes can increase the risk of loss or
additional damage in route to Traxxas.
• If possible, avoid the use of foam packing peanuts. If peanuts must
be used, please place the item to be repaired in a sealed bag.
• Include all the documentation and forms required to repair the
model. Along with a brief description of the problem.
• Include a daytime and evening phone number or e-mail
address that the service department may use to contact you with
questions or estimates regarding the repair.
• Include a return shipping address. It is surprising how often this
is overlooked. We must have a physical address in order to return
your product. It must be a street address. We cannot ship to Post
Office boxes.

Additional Non-Warranty Charges
Additional charges can result from the following.
• The product being returned for warranty service should be
cleaned of excess dirt and grime accumulations that would
hinder repair. Excessively dirty models with large amounts of
caked-on mud and oily grime may be subject to an additional
cleaning charge of $25.00(US) before repairs can proceed. Avoid
this potential charge by cleaning the model before returning it
for service.
• “Basket cases” of disassembled models returned for warranty
service may be subject to additional fees for reassembling
components not related to the warranty repair, if necessary to
allow the repaired product to be adequately tested. Standard
repair fees are currently $45.00/hour, billed in 15-minute
increments with a one-hour minimum. To avoid this charge do
not disassemble the model before returning it for service
