CONTENTS

WATER-RESISTANT VEHICLE WITH WATERPROOF ELECTRONICS

Your new Horizon Hobby vehicle has been designed and built with a combination of waterproof and water-resistant components to allow you to operate the product in many “wet conditions”, including puddles, creeks, wet grass, snow and even rain.

While the entire vehicle is highly water-resistant, it is not completely waterproof and your vehicle should NOT be treated like a submarine. The various electronic components used in the vehicle, such as the Electronic Speed Control (ESC), servo(s) and receiver are waterproof, however, most of the mechanical components are water-resistant and should not be submerged.

Metal parts, including the bearings, hinge pins, screws and nuts, as well as the contacts in the electrical cables, will be susceptible to corrosion if additional maintenance is not performed after running in wet conditions. To maximize the long-term performance of your vehicle and to keep the warranty intact, the procedures described in the “Wet Conditions Maintenance” section below must be performed regularly if you choose to run in wet conditions. If you are not willing to perform the additional care and maintenance required, then you should not operate the vehicle in those conditions.

CAUTION: Failure to exercise caution while using this product and

complying with the following precautions could result in product malfunction and/or void the warranty.

• Driving in wet conditions can reduce the life of the motor. The additional resistance of operating in water causes excess strain. Alter the gear ratio by using a smaller pinion or larger spur gear. This will increase torque (and motor life) when running in mud, deeper puddles, or any wet conditions that will increase the load on the motor for an extended period of time.

WET CONDITIONS MAINTENANCE

• Drain any water that has collected in the tires by spinning them at high speed. With the body removed, place the vehicle upside down and pull full throttle for a few short bursts until the water has been removed.

CAUTION: Always keep hands, ﬁ ngers, tools and any loose or hanging objects

away from rotating parts when performing the above drying technique.

• Remove the battery pack(s) and dry the contacts. If you have an air compressor or a can of compressed air, blow out any water that may be inside the recessed connector housing.

• Remove the tires/wheels from the vehicle and gently rinse the mud and dirt off with a garden hose. Avoid rinsing the bearings and transmission.

GENERAL PRECAUTIONS

• Read through the wet conditions maintenance procedures and make sure that you have all the tools you will need to properly maintain your vehicle.

• Not all batteries can be used in wet conditions. Consult the battery manufacturer before use. Caution should be taken when using Li-Po batteries in wet conditions.

• Most transmitters are not water-resistant. Consult your transmitter’s manual or the manufacturer before operation.

• Never operate your transmitter or vehicle where lightning may be present.

• Do not operate your vehicle where it could come in contact with salt water (ocean water or water on salt-covered roads), contaminated or polluted water. Salt water is very conductive and highly corrosive, so use caution.

• Even minimal water contact can reduce the life of your motor if it has not been certiﬁ ed as water-resistant or waterproof. If the motor becomes excessively wet, apply very light throttle until the water is mostly removed from the motor. Running a wet motor at high speeds may rapidly damage the motor.

NOTICE: Never use a pressure washer to clean your vehicle.

• Use an air compressor or a can of compressed air to dry the vehicle and help remove any water that may have gotten into small crevices or corners.

• Spray the bearings, drive train, fasteners and other metal parts with a water-displacing light oil. Do not spray the motor.

• Let the vehicle air dry before you store it. Water (and oil) may continue to drip for a few hours.

• Increase the frequency of disassembly, inspection and lubrication of the following:

- Front and rear axle hub assembly bearings.

- All transmission cases, gears and differentials.

- Motor—clean with an aerosol motor cleaner and re-oil the bushings with lightweight motor oil.

SRS4201 STABILITY ASSIST RECEIVER

AVC – ACTIVE VEHICLE CONTROL

The Spektrum SRS4201 receiver features Active Vehicle Control™ (AVC®) technology that responds similar to traction control in full-scale vehicles. In addition to traction control, AVC technology also increases steering stability during high-speed driving or while driving over rough terrain. As you increase the AVC sensitivity, the system increases steering stability and traction control, similar to reducing the amount of steering rate in a computer transmitter. Reducing the sensitivity value increases the amount of steering control from the transmitter. The SRS4201 receiver also enables you to quickly turn AVC on or off if you participate in organized racing.

IMPORTANT: You must use digital servos with the SRS4201 receiver. Using analog servos will reduce the performance of the system and may cause analog servos to overheat.

AVC SENSITIVITY

The ST RATE dial adjusts the sensitivity, or stability, value in the receiver. If you increase the sensitivity, the AVC system becomes more sensitive to the vehicle drifting left or right. You would use maximum sensitivity during high-speed driving or drag racing, when you want the vehicle to stay in a straight line. As the sensitivity value increases, the amount of steering travel decreases.

Turn the ST RATE knob counter-clockwise to reduce the sensitivity. Turn the ST RATE knob clockwise to increase the sensitivity. IMPORTANT: The ST RATE knob will only adjust the sensitivity

when the transmitter is bound to a DSMR™ receiver. When the transmitter is bound to a DSM®, DSM2® or DSM Marine receiver, the ST RATE knob controls the steering dual rate.

BINDING AND CALIBRATING THE RECEIVER

Your Spektrum DX2E comes prebound to the vehicle; however, if you need to rebind or calibrate the receiver, follow the instructions below.

1. Insert the Bind Plug in the BIND port on the receiver.

2. Connect a fully charged battery pack to the ESC.

3. Power on the ESC. The orange LED ﬂ ashes, indicating the receiver is in bind mode.

4. Center the ST TRIM and TH TRIM dials on the transmitter.

5. Press and hold the BIND button while powering on the transmitter.

6. Release the BIND button when the orange LED slowly ﬂ ashes. The transmitter and receiver

are linked when the orange LED is solid.

7. Pull the transmitter trigger to Full Throttle.

8. Push the transmitter trigger to Full Brake, then return the trigger to center.

9. Turn the transmitter steering wheel to Full Right.

10. Turn the transmitter steering wheel to Full Left, then return the steering wheel to center.

The orange LED ﬂ ashes once.

11. Remove the Bind Plug, then power off the receiver to save the settings.

12. Power off the transmitter.

CONTROL TEST

Perform a control test with the vehicle wheels off the ground. If the wheels rotate after the vehicle is powered ON, adjust the TH Trim knob until they stop. To make the wheels move forward, pull the trigger. To reverse them, wait for the wheels to stop, then push the trigger. When moving forward, the wheels should maintain a straight line without any steering wheel input. If not, adjust the ST Trim knob, so the wheels maintain a straight line without having to turn the steering wheel.

BEFORE RUNNING YOUR VEHICLE

1. Break in the differentials. While holding the chassis with only the left side tires ﬁ rmly on the ground, give the car about 1/8 throttle for 30 seconds. The right side tires should spin freely during this time. Repeat this with only the right side tires ﬁ rmly on the ground, allowing the left side tires to spin freely. Repeat this 2–3 times.

2. Check for free suspension movement. All suspension arms and steering components should move freely. Any binds will cause the car to handle poorly.

3. Charge the battery.

4. Check the calibration of the ESC. If recalibration is required, refer to the Tazer Mini

Brushless ESC section.

5. Adjust the transmitter settings to your desired conﬁ guration.

DRIVING PRECAUTIONS

• Maintain sight of the vehicle at all times.

• Inspect the vehicle for loose wheel hardware.

• Inspect the steering assembly for any loose hardware. Driving the vehicle off-road can cause fasteners to loosen over time.

• Do not drive the vehicle in tall grass. Doing so can damage the vehicle or electronics.

• Stop driving the vehicle when you notice a lack of power. Driving the vehicle when the battery is discharged can cause the receiver to power off. You may lose control of the vehicle.

• Do not apply the throttle in forward or reverse if the vehicle is stuck. Applying throttle in this instance can damage the motor or ESC.

• After driving the vehicle, allow the electronics to cool to ambient temperature before using the next battery pack.

RUN TIME

The largest factor in run time is the capacity of the battery pack. A larger mAh rating increases the amount of run time experienced.

The condition of a battery pack is also an important factor in both run time and speed. The battery connectors may become hot during driving. Batteries will lose performance and capacity over time.

Driving the vehicle from a stop to full speed repeatedly will damage the batteries and electronics over time. Sudden acceleration will also lead to shorter run times.

TO IMPROVE RUN TIMES

• Keep your vehicle clean and well maintained.

• Allow more airﬂ ow to the ESC and motor.

• Change the gearing to a lower ratio. A lower ratio lowers the operating temperature of the electronics. Use a smaller pinion gear or larger spur gear to lower the gear ratio.

• Use a battery pack with a higher mAh rating.
