Important Points to Remember

WARNING: CUTTING HAZARD!

The propeller is extremely sharp and spins at high speed. To avoid cuts or other severe injury, keep fingers clear of the propeller whenever batteries are connected. Remove or keep loose articles of clothing and long hair away from the propeller when handling and running the boat.

• Always follow local laws and ordinances with respect to running RC boats. Observe water safety rules and regulations.
• Never, under any circumstances, operate your model in any water where people are swimming or wading. Your model is fast and could cause injury if allowed to collide with anyone. Respect wildlife; avoid running in areas reserved for water fowl!
• Do not drive your model at night.
• 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 types and capacities. Use the same voltage and capacity for both batteries. Using mismatched battery packs could damage the batteries and electronic speed control.

Traxxas TQ 2.4GHz Radio System

Introduction

Your model includes the TQ 2.4GHz transmitter. When powered on, the TQ 2.4GHz will automatically locate and lock onto an available frequency, allowing multiple models to be raced together without frequency conflicts. Just switch on and drive!

The included TQ 2.4GHz radio system has been programmed for your model at the factory and does not require adjustment, but it does have settings you may need to access to maintain proper operation of your model. The detailed instructions (page 15) included in this manual will help you understand and operate the functions of the new TQ 2.4GHz radio system. For additional information and how-to videos, visit Traxxas.com.

Radio and Power System Terminology

Please take a moment to familiarize yourself with these radio and power system terms. They will be used throughout this manual.

• BEC (Battery Eliminator Circuit): The BEC can either be in the receiver or in the ESC. This circuit allows the receiver and servos to be powered by the main battery pack in an electric model. This eliminates the need to carry a separate pack of 4 AA batteries to power the radio equipment.
• Current: Current is a measure of power flow through the electronics, usually measured in amps. If you think of a wire as a garden hose, current is a measure of how much water is flowing through the hose.
• ESC (Electronic Speed Control): An electronic speed control is the electronic motor control inside the model. The XL-5 uses MOSFET power transistors to provide precise, digital proportional throttle control. Electronic speed controls use power more efficiently than mechanical speed controls so that the batteries run longer. An electronic speed control also has circuitry that prevents loss of steering and throttle control as the batteries lose their charge.
• Frequency band: The radio frequency used by the transmitter to send signals to your model. This model operates on the 2.4GHz direct-sequence spread spectrum.
• LiPo: Abbreviation for Lithium Polymer. Rechargeable LiPo battery packs are known for their special chemistry, which allows extremely high energy density and current handling in a compact size. These are high-performance batteries that require special care and handling. For advanced users only.
• mAh: Abbreviation for milliamp hour, a measure of the capacity of the battery pack. The higher the number, the longer the battery will last between recharges.
• 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 model that receives signals from the transmitter and relays them to the servos.
• Resistance: In an electrical sense, resistance is a measure of how an object resists or obstructs the flow of current through it. When flow is constricted, energy is converted to heat and is lost.
• Servo: Small motor unit in your model that operates the steering mechanism.
• Transmitter: The hand-held radio unit that sends throttle and steering instructions to your model.
• Trim: The fine-tuning adjustment of the neutral position of the servos, made by adjusting the steering trim knob on the face of the transmitter.
• Thermal Shutdown Protection: Temperature sensing electronics are used in the ESC to detect overloading and overheating of the transistor circuitry. If excessive temperature is detected, the unit automatically shuts down to prevent damage to the electronics.

Important Radio System Precautions

• Do not kink the receiver antenna wire. Kinks in the antenna wire will reduce range.
• DO NOT CUT any part of the receiver antenna wire. Cutting the antenna will reduce range.
• Extend the antenna wire in the model as far as possible for maximum range. It is not necessary to extend the antenna wire out of the hull, but wrapping or coiling the antenna wire should be avoided.
• Do not allow the antenna wire to extend outside the hull without the protection of an antenna tube, or the antenna wire may get cut or damaged, reducing range. It is recommended to keep the wire inside the hull (in the antenna tube) to prevent the chance of damage.

Diagram showing correct and incorrect antenna wire setup. Correct: Antenna wire extended, no kinks. Incorrect: Kinked wire, cut wire, bent metal tip, bent white wire.

2-channel radio system

The TQ 2.4GHz radio system, consisting of the receiver, the transmitter, and the servos. The system uses two channels: one to operate the throttle and one to operate the steering.

2.4GHz Spread Spectrum

This model is equipped with the latest R/C technology. Unlike AM and FM systems that require frequency crystals and are prone to frequency conflicts, the TQ 2.4GHz system automatically selects and locks onto an open frequency, and offers superior resistance to interference and "glitching."

Voltage

Voltage is a measure of the electrical potential difference between two points, such as between the positive battery terminal and ground. Using the analogy of the garden hose, while current is the quantity of water flow in the hose, voltage corresponds to the pressure that is forcing the water through the hose.

1. Remove the battery compartment door by pressing the tab and sliding the door open.
2. Install the batteries in the correct orientation, as indicated in the battery compartment.
3. Reinstall the battery compartment door and snap it closed.
4. Turn on the transmitter and check the status indicator for a solid green light.

If the status LED flashes red, the transmitter batteries may be weak, discharged or possibly installed incorrectly. Replace with new or freshly charged batteries. The power indicator light does not indicate the charge level of the battery pack installed in the model. Refer to the troubleshooting section on page 17 for more information on the transmitter Status LED codes.

Selecting Batteries for Your Model

Your model does not include batteries or a charger. One Traxxas iD® LiPo battery equipped with a Traxxas High-Current connector is required; 3-cell LiPo batteries are recommended for best performance. Use Traxxas iD® batteries with Traxxas iD® chargers for maximum performance and safer charging. The following chart lists available Traxxas LiPo batteries for your model:

Do not use NiMH batteries in this boat. The batteries will become extremely hot and damage or injury could occur. Refer to the Owner's Manual for more information.

WARNING: FIRE HAZARD!

Users of Lithium Polymer (LiPo) batteries must read the Warnings and Precautions beginning on page 4. You MUST use a LiPo charger for LiPo batteries or battery damage with the potential for fire will result.

Selecting a Charger for Your Model

Make certain you choose the correct type of charger for the batteries you select. Traxxas recommends you choose a genuine Traxxas EZ-Peak iD charger for safer charging and maximum battery life and performance.

If the status LED doesn't light green, check the polarity of the batteries. Check rechargeable batteries for a full charge. If you see any other flashing signal from the LED, refer to the chart on page 17 to identify the code.

Use the Right Batteries

Your transmitter uses AA batteries. Use new alkaline batteries (Part # 2914) or rechargeable batteries, such as NiMH (nickel-metal hydride) batteries, in your transmitter. Make sure rechargeable batteries are fully charged according to the manufacturer's instructions.

If you use rechargeable batteries in your transmitter, be aware that when they begin to lose their charge, they lose power more quickly than regular alkaline batteries.

Caution: Discontinue running your model at the first sign of weak batteries (flashing red light) to avoid losing control.

Battery iD

Traxxas recommended battery packs are equipped with Traxxas Battery iD. This exclusive feature allows Traxxas battery chargers (sold separately) to automatically recognize connected battery packs and optimize the charge settings for the battery. This eliminates the need to worry over charger settings and menus for the easiest and safest charging solution possible. Visit Traxxas.com to learn more about this feature and available Traxxas iD chargers and batteries.

Removing and Installing the Hatch

Your model includes an innovative latching system for securing the hatch to the boat hull.

To remove the hatch:

1. Using the tool supplied with your boat, unlock the four hatch nuts on the boat hatch by turning each to its stop.
2. Carefully lift the hatch from the boat hull.

To reinstall the hatch:

1. Position the hatch on the boat hull.
2. Lock the four hatch nuts by turning each to its stop.

Note: To help prevent accumulation of water in the hull, NEVER operate your boat with the hatch removed.

Accessory toolless wing nuts installation

The included accessory wing nuts are interchangeable with the hatch nuts. Remove the 3x8mm countersunk cap screws to remove the hatch nuts (A). Use the four removed screws to install the wing nuts (B).

Illustration showing removal of hatch nuts and installation of wing nuts.

Installing the Battery Packs

Disruptor uses hook-and-loop straps to secure the battery pack. Loosen the straps, slide the battery pack beneath them, and tighten the straps to hold the battery snugly against the battery tray. They should be tight to prevent the battery from sliding. Assemble the straps as shown in the illustration.

Positioning the Battery Pack

• Battery Pack Aft: This is the standard battery position. Placing the battery pack at the aft end of the battery tray will work best for Disruptor in all water and wind conditions.
• Battery Pack Forward: Positioning the battery pack at the front of the battery tray will give Disruptor the greatest stability when driving in rough, choppy waters.

Traxxas TQ 2.4GHz Radio System

Radio System Controls

Diagram of the Traxxas TQ 2.4GHz transmitter showing steering wheel, throttle trigger, and trim controls.

Radio System Rules

• Always turn your transmitter on first and off last. This procedure will help to prevent your model from receiving stray signals from another transmitter, or other source, and running out of control. Your model has electronic fail-safes to prevent this type of malfunction, but the first, best defense against a runaway model is to always turn the transmitter on first and off last.
• Always use new or freshly charged batteries for the radio system. Weak batteries will limit the radio signal between the receiver and the transmitter. Loss of the radio signal can cause you to lose control of your model.
• Always turn on the transmitter before plugging in the battery.

Radio System Basic Adjustments

Steering Trim

Slowly turn the steering trim knob to precisely set the steering neutral point. To adjust, drive the boat forward slowly while "steering" with the trim knob until the boat travels in a straight line with no steering input.

Channel Reversing

The TQ 2.4GHz transmitter has been programmed with the correct servo direction settings for your model and should not require adjustment. These instructions are for reference and troubleshooting only.

Reversing a channel reverses the direction of the corresponding servo. For example, if you turn the steering wheel to the right and the model turns left, Channel 1 would need to be reversed to correct the servo direction. Use the following procedures to reverse the steering and throttle channels, if necessary. Servo reversing should only be required if you accidentally reset the direction of a channel. Do not reverse the steering or throttle channels unless necessary.

Steering reversing procedure:

1. Press and hold the SET button on the transmitter for two seconds. The status LED will flash green.
2. Turn and hold the steering wheel to the full left or full right position (it does not matter which position you choose).
3. While holding the steering wheel in position, press the SET button to reverse the channel.
4. The channel is now reversed. Confirm correct servo operation before running your model.

Using the Radio System

Remember, always turn the transmitter on first and off last to avoid damage to your model.

Fail-Safe

Your Traxxas radio system is equipped with a built-in fail-safe function that returns the throttle to its last saved neutral position in the event of a signal loss. The LED on the transmitter and the receiver will rapidly flash red when the fail-safe mode is activated. If fail-safe activates while you are operating your model, determine the reason for signal loss and resolve the problem before operating your model again.

When rechargeable batteries begin to lose their charge, they will fade much faster than alkaline dry cells. Stop immediately at the first sign of weak batteries. Never turn the transmitter off when the battery pack is plugged in. The model could run out of control.

The TQ 2.4GHz Radio System has been pre-adjusted at the factory for correct operation with your model. The adjustment should be checked before running the model in case of movement during shipping. Here's how:

1. Turn the transmitter switch on. The status LED on the transmitter should be solid green (not flashing).
2. Elevate the model on the included stand so that the propeller is off the ground.

WARNING: CUTTING HAZARD!

The propeller is extremely sharp and spins at high speed. To avoid cuts or other severe injury, keep fingers clear of the propeller whenever batteries are connected. Remove or keep loose articles of clothing and long hair away from the propeller when handling and running the boat.

3. Plug the battery pack in the model into the speed control. This turns the speed control on.
4. Turn the steering wheel on the transmitter back and forth and check for rapid operation of the steering servo. Also, check that the steering mechanism is not loose or binding. If the steering operates slowly, check for weak batteries.
5. When looking down at the rear of model, the rudder should be pointing straight back. If the rudder is turned slightly to the left or right, slowly adjust the steering trim control on the transmitter until it is pointing straight back.
6. Gently operate the throttle trigger to ensure that you have forward and reverse operation, and that the motor stops when the throttle trigger is at neutral. WARNING: Do not apply full throttle in forward or reverse while the model is elevated.
7. Once your adjustments have been made, turn the receiver and the model off by unplugging the batteries, then switch off the transmitter. The transmitter is always switched off last.

Range-Testing the Radio System

Before each running session with your model, you should range-test your radio system to ensure that it operates properly.

1. Turn on the radio system and check its operation as described in the previous section.
2. Have a friend watch the model. Make sure hands and clothing are clear of the propeller and other moving parts on the model.
3. Walk away from the model with the transmitter until you reach the farthest distance you plan to operate the model.
4. Operate the controls on the transmitter once again to be sure that the model responds correctly.
5. Do not attempt to operate the model if there is any problem with the radio system or any external interference with your radio signal at your location.

Higher Speeds Require Greater Distance

The faster you drive your model, the more quickly it will near the limit of radio range. At top speed, models can cover anywhere between 50 to 100 feet every second! It's a thrill, but use caution to keep your model in range. If you want to see your model achieve its maximum speed, it is best to position yourself in the midpoint of the model's running area, not the far end, so you drive back and forth past your position. In addition to maximizing the radio's range, this technique will keep your model closer to you, making it easier to see and control.

Your model's radio system is designed to operate reliably up to the approximate distance that it is no longer easy or comfortable to see and control the model. Most drivers will struggle to see and drive their model at distances farther than a football field (300+ feet). At greater distances, you could lose sight of your model and you may also exceed the radio system's operating range which will cause the fail-safe system to activate. For best visibility and control of your model keep your model within 200 feet, regardless of the maximum range available.

Traxxas TQ 2.4GHz Radio System

No matter how fast or far you drive your model, always leave adequate space between you, the model, and others. Never drive directly toward yourself or others.

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 from the model will reduce radio range.

TQ 2.4GHz Binding Instructions

For proper operation, the transmitter and receiver must be electronically 'bound.' This has been done for you at the factory. Should you ever need to re-bind the system or bind to an additional transmitter or receiver, follow these instructions. Note: The receiver must be connected to a 4.8-6.0v (nominal) power source for binding and the transmitter and receiver must be within 5 feet of each other.

1. Press and hold the SET button on the transmitter.
2. Turn on the transmitter and release the SET button. The status LED will flash red slowly, indicating that the transmitter is in bind mode.
3. Press and hold the LINK button on the receiver.
4. Plug in the battery to turn on the speed control. Release the LINK button.
5. When the LEDs on both the transmitter and the receiver turn solid green, the system is bound and ready for use. Confirm that the steering and throttle operate properly before driving your model.

Setting Up the Antenna

The receiver antenna has been set up and installed from the factory. The antenna is secured by a 3x4mm set screw. To remove the antenna tube, simply remove the set screw with the included 1.5mm wrench.

When reinstalling the antenna, first slide the antenna wire into bottom of antenna tube until white tip of antenna is at top of tube under the black cap. Next insert the antenna tube into the mount while making sure that antenna wire is in slot in the antenna mount, then install the set screw next to the antenna tube. Use the supplied 1.5mm wrench to tighten the screw just until the antenna tube is securely in place. Do not over tighten. Do not bend or kink the antenna wire! Do not shorten the antenna tube.

Electronic Speed Control Adjustments

The VXL-4s Marine electronic speed control's default settings were programmed at the factory and should not require adjustment for normal operation. The following information is helpful to confirm the settings or allow you to customize the settings for your needs.

ATTENTION: USING LiPo BATTERIES

The VXL-4s Marine electronic speed control is designed to operate on 2s, 3s or 4s LiPo battery power. When you turn your model on, the speed control's status LED is green, indicating that Low Voltage Detection is activated to prevent over-discharging of LiPo batteries. LiPo batteries are intended only for the most advanced users that are educated on the risks associated with LiPo battery use.

DO NOT use Nickel Metal Hydride (NiMH) batteries with this model. The batteries will become extremely hot and damage or injury could occur.

VXL-4s Marine Profile Selection

The speed control is factory set to Profile 1. To change the profile, follow the steps on described below. The speed control should be connected to the receiver and the transmitter should be adjusted as described previously. The profiles are selected by entering the programming mode.

• Profile 1 (Sport Mode): 100% Forward, 100% Reverse
• Profile 2 (Training Mode): 50% Forward, 50% Reverse

Note: Self Righting may not work as expected in Training Mode. See the Self Righting and Boat Retrieval sections for additional instructions.

Selecting Sport Mode (Profile 1)

1. Place the boat on the included stand and make sure objects and fingers are clear of the propeller.
2. Turn on the transmitter. Pull and hold the trigger to full throttle.
3. While holding full throttle, connect a fully charged battery to the VXL-4s Marine ESC. It will turn on automatically.
4. Continue to hold the transmitter trigger at full throttle. After about two seconds, the red LED will blink once.
5. Move the trigger to neutral. The ESC is ready for use and is set to Profile 1.

Selecting Training Mode (Profile #2)

1. Place the boat on the included stand and make sure objects and fingers are clear of the propeller.
2. Turn on the transmitter. Pull and hold the trigger to full throttle.
3. While holding full throttle, connect a fully charged battery to the VXL-4s Marine ESC. It will turn on automatically.
4. Continue to hold the transmitter trigger at full throttle. After about two seconds, the red LED will blink.
5. Continue to hold the transmitter trigger at full throttle. After about two more seconds (4 seconds total), the red LED will blink twice.
6. Move the trigger to neutral. The ESC is ready for use and is set to Profile 2.

Thermal Shutdown Protection

The VXL-4s Marine is equipped with thermal shutdown protection to guard against overheating caused by excessive current flow. If the operating temperature exceeds safe limits, the VXL-4s Marine will automatically shut down and the ESC's red LED will blink. The LED will continuously blink red even if the throttle trigger is moved back and forth. After the ESC cools down to a safe level, the ESC will once again function normally.

Over-Voltage Detection

The VXL-4s Marine speed control also detects when too much voltage is being input. If a battery with more than 14.8 volts is connected to the speed control, it will not operate. The red and green LEDs will blink. Unplug the battery and install a battery with 14.8 volts or less.

Throttle Neutral Protection

If the transmitter's throttle neutral position is moved after the VXL-4s Marine speed control has been switched off, the speed control will not recognize the new position when it is turned back on and will not operate the throttle. This prevents the boat from running out of control due to an accidental change of the neutral position. If Throttle Neutral Protection detects that the throttle neutral position has changed, the VXL-4s Marine speed control's green LED will blink steadily. Return the throttle trim position to neutral to resume normal throttle operation.

Driving Your Model

Caution! If your model suddenly stops running or runs very slowly, release the throttle immediately! Refer to Troubleshooting on page 25 for more information.

Now it's time to have some fun! This section contains instructions on driving and making adjustments to your model. Before you go on, here are some important precautions to keep in mind. Disruptor's self-righting capabilities allow more extreme maneuvers than standard boats. If the boat flips or is blown over, the boat can be returned to an upright position with a few simple steps (see the Self Righting section for instructions).

• Do not leave the boat sitting in the water for extended periods of time without driving it. Parking the boat in the water or excessive use of reverse can allow water to slowly enter the hull from the stuffing tube. Always remove the boat from the water and disconnect the batteries from the ESC when not in use.
• It is normal for water to accumulate inside the boat. Empty any standing water out of the boat between runs. Remove the drain plug from the transom and tip the boat backwards to drain the water. After the water is drained, reinstall the drain plug.
• Use extra caution when traveling into the wind and/or against the direction of waves. The added pitch motion caused by driving into cresting waves, combined with wind blasts, tends to lift the boat out of the water further and might cause the boat to blow over backwards.
• If the boat starts getting very light on the water (about to blow over), reduce throttle to settle the hull back into the water.
• Always be ready to reduce the throttle if your model appears to be unstable or "chine walking" (rocking violently from side to side). Make trim tab or weight placement changes to reduce chine walking, as this behavior can cause a crash in rougher water.
• Always reduce the throttle when turning, especially in rough water. Once the boat has begun leaning into the corner, increase throttle to maintain speed and keep the bow up.
• Use caution when driving parallel to waves or wind chop. The waves will cause excess rocking, and may cause the boat to spin out or crash unexpectedly.
• When traveling at high speeds (40+ mph), be very gentle with control inputs to avoid hooking or flipping the boat.
• Do not operate the boat continuously at low speeds when using LiPo batteries. The ESC and motor could overheat from lack of cooling water flow.
• Remove the propeller for transportation to avoid accidentally breaking it.
• To prevent spin outs, avoid steering sharply at high speed.
• Jumping your model or towing anything with it should not be attempted.
• Return your model to shore at the first sign of weak batteries. Your model will begin to slow and the controls will become sluggish.

Cavitation

If your model is running at full throttle but is only barely moving forward, the propeller is cavitating. Try advancing the throttle slowly to get your model on plane. If you are having trouble with cavitation, check the propeller for nicks or tangled debris. Your model's propeller is specially designed for its application and is very sensitive to any changes or modifications. If a prop is damaged, it should be replaced.

Where to Run

Select a body of fresh water, which is calm and free of debris, tree stumps, moss, etc. Do not drive your model in extremely rough, choppy water or in high wind (more than 15mph); these conditions could cause your model to flip over. Also, find a clean, stable area of shoreline as a launch site. The water must be at least 10 inches deep. 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 become disabled. Running your model in salt water is not recommended. Damage from corrosion is not covered by the warranty. Your model is too fast to run in a swimming pool.

Self Righting

Your Disruptor is equipped with Traxxas Self Righting to return the boat to an upright position if it accidentally flips over in the water.

• When using a 3-cell or 4-cell LiPo battery: Wait a few seconds for the propeller to stop completely and the boat to stop moving. Quickly apply 100% reverse throttle and the boat will self right.
• When using a 2-cell LiPo battery: Wait a few seconds for the propeller to stop completely and the boat to stop moving. Briefly apply 100% full throttle, and then apply 100% reverse throttle. The boat will rock and flip until it self rights. This may require several attempts.

Note: If your boat does not self right, follow the instructions in the Boat Retrieval section to pull your boat slowly back to shore.

Boat Retrieval

DANGER! DO NOT SWIM OR WADE INTO THE WATER TO RETRIEVE A BOAT.

If your boat will not self right or return to shore, and 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 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.

Adjusting Your Model

Run Time

Your model is able to achieve long run times due to the greater efficiency of the high voltage electrical system. A large factor affecting run time is the type and condition of your batteries. The milliamp hour (mAh) rating of the batteries determines how large their "fuel tank" is. A 3000 mAh battery pack will theoretically run twice as long as a 1500 mAh pack. Because of the wide variation in the types of batteries that are available and the methods with which they can be charged, it's impossible for us to give you exact run times for your model. Another major factor which affects run time is how your model is driven. Our experience has shown that the run times are shorter when the boat is driven continuously at top speed.

Tips for Increasing Run Time

• Use a high-quality peak-detecting charger.
• Vary your speed. Continuous high speed shortens the run time on your model.
• Maintain your model. Do not allow debris or damaged parts to cause binding in the drivetrain. Keep the motor clean and the motor bearings lightly lubricated.
• Apply the throttle smoothly. Hard acceleration, especially from a stop, will shorten your run time.

Adjusting the Trim Tabs

Disruptor features stainless-steel trim tabs to help set the angle of the boat's hull as it rides in the water. Setting the trim angle correctly will provide maximum speed and efficiency from your model. From the factory, the trim tabs are set for best all-around performance and stability at Disruptor's maximum speed, but you can experiment with their position to improve performance. Slightly bending the tabs down will cause the bow to run closer to the water, "wetting" more of the hull and increasing stability. Be sure to set the left and right trim tabs equally.

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. Remove the wire clamp by removing the two 2.5x8mm cap screws.
2. Remove the cover by removing the two 3x10mm cap screws.
3. 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.
4. Unplug the servo cables from the receiver and remove the receiver.

Receiver Installation

1. Using double-sided adhesive foam tape, install the receiver into the box. Make sure the LED light pipe is aligned with the receiver LED.

Note: For best performance, it is recommended that the receiver be installed in the original orientation as shown.

2. Install the electronic speed control (ESC), servo, and antenna wiring through the receiver box top.
3. Plug ESC and servo wires into the receiver (see page 12).
4. Make sure the O-ring is properly seated into the groove in the receiver box bottom so that the cover will not pinch it or damage it in any way.
5. Place receiver box top onto receiver box bottom and install and tighten the two 3x10mm cap screws securely.
6. Inspect the cover to make sure that the O-ring seal is not visible.
7. Arrange the wires neatly using the wire guides on the receiver box top (B). Excess ESC and servo wiring should be bundled inside the receiver box. Pull out all available antenna wiring from the receiver box.
8. Apply a small bead of silicone grease (part #1647) to the foam on the wire clamp (C).
9. Install the wire clamp and tighten the two 2.5x8mm cap screws securely (D).

Diagram showing receiver box assembly steps A, B, C, D.

Maintaining Your Model

Your model requires maintenance in order to stay in top running condition. The following procedures should be taken very seriously. Form the habit of visually inspecting the mechanical integrity of the model before and after each run.

Inspect the model for obvious damage or wear:

• It is normal for water to accumulate inside the boat. Empty any standing water out of the boat between runs. Remove the drain plug from the transom and tip the boat backwards to drain the water. After the water is drained, reinstall the drain plug.
• Check the wiring for any frayed wires or loose connections.
• Check the tightness of the set screws in the collars on the steering linkages in the propeller. Thread-locking compound can be applied to these screws to prevent them from loosening. Thread-locking compound is not needed on any other screws or fasteners on your boat. If you choose to apply thread-locking compound on other screws or fasteners, ONLY use plastic safe thread-locking compound on any screws that attach to the boat hull.
• Check the mounting of the receiver and servo.
• Check the tightness of the propeller. Visually inspect the prop for nicks, dings, and warping. Replace if any damage is noticed.
• Check the operation of the radio system, especially the condition of the batteries.
• Visually inspect the hull for any cracks, damage, or possible leaks.

After each running session:

• Make certain the motor is completely dry, particularly the bearings.
• Lubricate the motor bearings with light oil.
• Release the drive cable from the collet as explained on page 24, and remove the drive cable by pulling the propeller away from the drive strut. Thoroughly dry the drive cable and lubricate it with the marine grease included with your model.
• While the drive cable is removed from the model, dry and lubricate the bushings in the drive strut. Reinstall the drive cable by reversing the removal steps. Push the drive cable in all the way; drive dog spacing will be approximately 5mm.
• Keep all of the screws in the drive system tight.

Storage:

• Disconnect and remove all batteries.
• Thoroughly clean and dry the model before storing it.
• Always store the model with the hatch removed. This will allow harmful moisture and condensation to evaporate.

Centering your Servo

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.

1. If the radio system is already installed in the boat, disconnect the servo horn from the servo.
2. Connect the steering servo to channel 1 on your receiver and the electronic speed control to channel 2.
3. Place fresh "AA" batteries in the transmitter and turn the power switch on.
4. Turn the throttle and steering trim adjustments to the center position.
5. Keep fingers and objects away from the propeller. Connect a fresh battery to the electronic speed control. The servo will automatically jump to its center position.
6. The servo horn is now ready to be installed.
7. Be careful not to move the servo shaft when installing the linkages. Readjust the electronic speed control as described in the previous section.

Always wear eye protection when using compressed air or spray cleaners and lubricants.

Diagram showing the Water Cooling Diagram with ESC, Motor, Water Pickups, and Water Outlet labeled.

Radio Tray Removal

Disruptor's unique power module allows you to easily remove the motor, drive system, and electronics as a unit for easy access to the hull interior. With the power module removed, you can easily work on the drive system or electronics without the entire hull taking up your bench space. To remove the power module, follow these steps:

1. Loosen the drive cable collet. Using the two 10mm wrenches supplied, grip the collet base and collet clamp. Rotate the parts away from each other in the direction shown to loosen the clamp. You do not have to fully unthread the collet.
2. Remove the drive cable. Pull the propeller away from the drive strut. The cable will come out with the propeller. There is no need to remove the prop from the cable.
3. Unplug the two water cooling inlet tubes (A) and two outlet tubes (B).
4. Remove the two 4x12mm button-head screws from the tube clamp.
5. Remove the 3x15mm cap-head screw securing the servo horn to the steering linkage.
6. Remove the six 3x10mm self-tapping button-head screws from the power module mount.
7. Gently lift the power module from the motor end.
8. Installation is the reverse of removal.

Note: Sometimes the stuffing tube sticks in the seal. Extra force may be required to break it free.

Diagram showing steps for radio tray removal with screw callouts.

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 20 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 20 for recovery.
• The model might have struck an object in the water causing driveline damage. Refer to the Boat Retrieval section on page 20 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 battery 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 battery 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-4s Marine 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 20 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 21).
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. Traxxas iD Power Cell battery packs are specially constructed for durability and performance in high-power Traxxas models. Traxxas recommends the EZ-Peak Plus iD charger, part #2970, for quick charging. See Traxxas.com for more information.

For the best performance, we highly recommend the Disruptor's factory-installed brushless system. It is optimized for the best performance, reliability, and ease of use in the Disruptor, and fully supported by Traxxas customer service.
