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.

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 certified 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.
• 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, fingers, 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.
  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.

RECEIVER ANTENNA
The SR315 receivers feature a coaxial antenna design for easy installation in almost any model. Think of the last 1 inch (32mm) on the tip of the antenna as the active portion of the antenna, the coaxial portion leading up to it is just an extension. Install the antenna so the active portion is positioned as high as possible in the vehicle, and not “in the shadow” of any carbon fiber or metal. This case of the receiver can accept an antenna tube directly, making optimal antenna placement easy (antenna tube not included).

WARNING: Do not kink, cut or damage the antenna wire. The antenna is made of a coaxial wire; if the outer sheath becomes damaged, the receiver will not work properly. If the antenna is damaged in any way, replace the antenna before attempting to use the receiver.

BINDING THE RECEIVER

Binding is the process of programming the receiver to recognize the GUID (Globally Unique Identifier) code of a single specific transmitter. In the event of a loss of signal, the receiver will default the servo outputs to the failsafe position. The failsafe positions are set during binding; Leave the throttle and steering at the neutral positions during binding.

1. Press and hold the bind button, and Power ON the receiver; the orange LED will begin to flash.
2. Set the trims and control positions at the desired failsafe settings, press and hold the bind button, and power ON the DX3 Smart transmitter.
3. When the orange LED on the DX3 Smart transmitter remains lit, it is connected to the SR315 receiver.

You must rebind when:

• Different failsafe positions are desired e.g., when the throttle or steering reversing has been changed.
• Binding the receiver to a different transmitter.

OPERATING THE VEHICLE

• ALWAYS turn on your transmitter before you turn on the receiver in the vehicle.
• ALWAYS power off the receiver before turning your transmitter off.
• ALWAYS operate your vehicle in a wide open area. Operating the vehicle in a small space or indoors can cause overheating at low speeds. Operating at low speed increases heat in the electronic speed control (ESC). Overheating can damage the vehicle and failure may result.

POWERING ON THE VEHICLE

1. Center the ST TRIM and TH TRIM dials on the transmitter.
2. Power on the transmitter.
3. Open the body as described in the Installing the Vehicle Battery section.
4. Install and connect a fully charged battery pack to the ESC.
5. Power on the ESC.
6. Close and latch the body.
7. Perform a test of the transmitter’s control of the vehicle with the vehicle’s wheels off the ground.
8. Start driving slowly. If the vehicle does not go straight, adjust the ST dial on 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.

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 offroad 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.

BEFORE RUNNING YOUR VEHICLE

1. Break in the differentials. While holding the chassis with only the left side tires firmly 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 firmly 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 150A Brushless ESC section.
5. Adjust the transmitter settings to your desired configuration.

DESCRIPTIONS

1. Running Mode

   • Forward Only with Brake: Intended for competition use, this mode allows only forward and brake controls.
   • Forward/Reverse with Brake: This mode is the basic all-around mode, allowing forward, reverse and brake controls. To engage reverse while moving forward, apply the brake until the vehicle has come to a complete stop, release brake, then apply the brake again. While braking or in reverse, engaging the throttle will result in the vehicle immediately accelerating forward.

2. Drag Brake Force
   Adjusts the amount of brake automatically applied when the throttle is returned to the neutral position. This simulates the engine braking effect of a full-scale vehicle, allowing improved turn-in and your vehicle’s general response to controls.

3. Low Voltage Cutoff
   This function helps to prevent battery over-discharge. The ESC continuously monitors the battery’s voltage. If the voltage falls below the voltage threshold for 2 seconds, the output power shuts off and the red LED flashes twice repeatedly. The cutoff threshold calculation is based on individual Li- Po cell voltage. For Ni-MH batteries, if the voltage battery pack is higher than 9.0V, it will be treated as a 3-cell Li-Po battery pack; if it is lower than 9.0V, it will be treated as a 2-cell Li-Po battery pack. Example: for a 8.0V Ni-MH battery pack used with a 2.6V/cell threshold, it will be treated as a 2-cell Li-Po battery pack and the low-voltage cut-off threshold will be 5.2V (2.6×2=5.2).

4. Start Mode (Punch)
   Sets the initial throttle punch when the car accelerates. Level 1 gives a very soft initial acceleration and level 4 gives a stronger initial acceleration.

5. Max Brake Force
   Adjusts the maximum braking force. A higher value provides stronger braking, but can also cause the wheels to lock, resulting in loss of control of the car.

6. Max Reverse Force
   This parameter adjusts the maximum power when travelling in reverse.

7. Neutral Range
   Adjusts the throttle sensitivity around the neutral point. A higher value results in the throttle having to be moved more for the vehicle to move forward, backward or brake.

8. Timing
   Adjusts the motor drive current timing. More timing gives more performance, but can lower efficiency and cause damage to the motor and/or ESC by overload or overheating.
   NOTICE: Always ensure the motor timing is set correctly. Failure to set the motor timing correctly can result in damage to the motor and ESC. Refer to the manufacturer instructions for recommended timing settings.

9. Motor Rotation
   Allows you to make this change in the ESC so no wires need to be changed between the ESC and the motor.

10. BEC Voltage
    Determines the output voltage of the BEC to the receiver and servo.

SPEKTRUM™ FIRMA 2050KV 4-POLE BRUSHLESS MOTOR (SPMXSM1700)

PRECAUTIONS

• Never touch moving parts.
• Never disassemble while the batteries are installed.
• Always let parts cool before touching.
• Rated for up to 8S batteries.

GEARING
The stock pinion gear is a MOD 1,12 tooth, 5mm shaft pinion (LOSA3572). Installing a pinion gear with fewer teeth will provide greater torque but will reduce top speed. Likewise, a pinion gear with more teeth will reduce torque and increase top speed. Care should be taken when installing larger pinion gears as this can “overhear” the vehicle, resulting in overheating of the motor and ESC. When testing different gearing options, pay close attention to the temperature of the motor and speed control to ensure you are operating within the temperature range of the components. The motor or ESC should never be so hot that it cannot be touched. If temperatures are too hot, a different gearing combination with a lower pinion gear and/or higher spur gear is suggested.

CHANGING THE PINION GEAR/GEAR RATIO

1. Loosen the two screws holding the motor in place, loosen the pinion gear set screw and remove the pinion gear.
2. Remove the motor mounting screws to remove the motor, or adjust the motor to the location for the corresponding pinion gear.
3. Install the new pinion gear on your motor. Place the pinion gear on the end of the motor shaft so that it lines up flush with the spur gear and the set screw is located over the flat on the shaft.
4. Tighten the pinion gear on the motor shaft and tighten the motor mounting screws after ensuring proper gear mesh.

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 airflow to the ESC and motor.
• Change the gearing to a lower ratio. A lower ratio decreases 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.
• Use the optimum charger to charge battery packs (Visit your local hobby dealer for more information).
