Required Equipment
To operate the Blast, you will need four (4) “AA” size batteries for your transmitter.
Where to Run
Select a body of water (must be at least 10 inches deep) that is calm and free of debris, tree stumps, moss, etc. Also, find a clean, stable area of shoreline for launching. Be aware that some ponds restrict the use of model boats. Always choose a launch site that is downwind so that the wind and waves will drift the boat back to you if it should ever flip over. Do not run the Blast in salt water.
Preparing to Run

Charge the battery pack The Traxxas Battery Charger** is a fully featured NiMH (Nickle Metal Hydride)charger. It features 4-amp charge current for fast charging and advanced peak detection to optimize every charge. Take this compact charger with you wherever you want to have radio-controlled fun!
Do not charge batteries inside of an automobile. Read the Safety Precautions section of this guide.

1. Plug the charger into a 12-volt automotive auxiliary power socket. The charger is compatible with 12-volt automotive auxiliary power sockets only. The LED on the charger will glow red to indicate it is ready to charge a battery.
2. Connect the battery to begin charging. Plug the battery into the charger. The charger’s LED will flash green, indicating that charging has begun. The flashing green LED on the charger indicates the charge progress.
3. Disconnect the battery when charging is complete. The Traxxas 4amp DC charger uses sophisticated voltage-detection circuitry to monitor the battery and automatically stop charging whenthe pack has reached maximum capacity. When the battery is fully charged, the LED will light solid green. The battery will be warm in your hand.  isconnect the battery and go have fun.

CHARGE PROGRESS

**Note: This charger is designed for use only with Traxxas NiMH batteries with iD. Legacy Traxxas High-Current  Connectors are not compatible with this charger. DO NOT try to force legacy connectors into the charge connector.

Note: If there is a problem with the battery, such as a short circuit, the charger’s LED will flash red. Disconnect the battery and unplug the charger from its power source to learn the error. Determine the cause of the error before continuing.
Installing Transmitter Batteries
The transmitter requires 4 AA alkaline or rechargeable batteries.
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.

Setting Up the Antenna

1. Slide the antenna wire into the bottom of the antenna tube until the white tip of the antenna is at the top of the tube under the black cap.
2. Insert the base of the tube into the antenna post. Take care not to crimp the antenna wire.
3. To prevent loss of radio ange, do not kink or cut the black wire, do not bend or cut the metal tip, and do not bend or cut the white wire at the end of the metal tip.

Installing the Battery Pack
The included 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 ensure the battery. The Blast is not designed to use 7-cell (8.4 volts) battery packs.

Transmitter Controls

**** The TQ 2.4GHz transmitter has a directional antenna. For maximum range, hold the antenna upright and pointed in the direction of the model. Pointing the transmitter away rom the model will reduce radio range.

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.

• 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 another source, and running out of control.
• Turn the transmitter switch on. The status LED on the transmitter should be solid green (not flashing).
• Turn on the receiver 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. Check for rapid operation of the steering servo and that none of the steering mechanisms 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 you have a full operation (propeller reaches full speed), and that the propeller stops spinning when the throttle trigger is at neutral.
• Once adjustments are made, turn off the receiver on your Blast, followed by the hand-held transmitter.
• 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 to operate 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. Nothing connects to the other terminals on the receiver.
Place fresh “AA” batteries in the transmitter and turn the power switch on. Adjust trim to “0” 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. Before you go on, here are some important precautions to keep in mind.

• Without proper care, some parts of your model can be seriously damaged due to contact with water. Know that additional maintenance procedure 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 TQ 2.4GHz 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. Saltwater is highly conductive and highly corrosive. Use caution if you plan to run your model near a beach.
• Select a body of water (at least 10 inches deep) that 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, 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 is very sensitive to any changes or modifications. If the propeller 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 receiver box O-ring and cover are installed correctly and securely. Make sure the screws are tight and the blue O-ring is not visibly 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 from the boat between runs. Drill a small hole 1/16” from 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). Drill a small hole here Drill a small hole here

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). Thread locking 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 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 propeller 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 that holds the top hatch.

13. Before operating the Blast, make certain the water pickup (A) and the exit tube (B) are clear of debris and are properly connected. Otherwise, motor overheating may occur.

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 help with 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 stepcan improves 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 the box. The patented wire clamp feature gives you the ability to alsoinstall aftermarket radio systems and maintain the watertight features 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 and ESC cables from the receiver and remove the receiver.

Receiver Installation

1. Always install the wires into the receiver 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 a small bead of silicone grease (Traxxas part #1647) to the wire clamp.
5. Install the wire clamp and tighten the two2.5x8mm cap screws securely.
6. Install the receiver into the box and plug the wires into the 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 inthe 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 propeller may begin to cavitate. As the outdrive is trimmed down, the bow of the boat is lowered, 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 image). Pull the propeller shaft  ntil there is no more than 1mm of distance at “arrow 2” in the drawing. Retighten the set screw.
Boat Retrieval
DANGER! DO NOT SWIM OR WADE INTO THE WATER TO RETRIEVE A BOAT. If your Blast accidentally flips over and fills with water, it is equipped with foam flotation to help prevent it from sinking. If you have chosen your launch sight carefully (downwind), your model will probably drift back to you on its own. If there is no wind, you will need a tennis ball and a length of the 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 the driveshaft tube is located underneath the sealed receiver box. Storage Drain all water out of the Blast and thoroughly dry it before

storage
Store the Blast with the hatch cover removed so that any remaining moisture can to evaporate.
Painting the Hull
If you wish to paint your hull some other color besides 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.
