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 main-tenance 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 hang-ing 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.

SR315 RECEIVER

Specifications

• Type : Dual Protocol 3 Ch Receiver (SLT/DSMR)
• Dimensions (LxWxH): 32.5 x 21.5 x 12.4mm Antenna
• Length: 90mm
• Channels: 3
• Weight: 6g
• Band: 2.4GHz
• Voltage Range: 3.5–9.6V
• Bind Type: Bind Button
• Failsafe: Hold the steering wheel and throttle trigger in the desired failsafe positions during binding

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. The 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 SR315 receiver.

You must rebind when:

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

POWERING ON THE VEHICLE

1. Center the ST TRIM and TH TRIM dials on the transmitter.
2. Power on the transmitter.
3. Remove the body from the vehicle.
4. Connect a fully charged battery pack to the ESC.
5. Power on the ESC.
6. Re-install the body on the vehicle.
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.

OPERATION

• 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.

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 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 130A Sensored Brushless ESC section.
5. Adjust the transmitter settings to your desired configuration.

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.
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 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.

SPEKTRUM™ FIRMA™ SMART 130A BRUSHLESS ESC (SPMXSE2130S)

SPECIFICATIONS

ESC LED STATUS

• No ESC LEDs will glow when there is no throttle input from the transmitter.
• The red ESC LED glows when there is any throttle input from the transmitter.

AUDIBLE WARNING TONES

1. Input Voltage: The ESC checks the in put voltage when it is powered ON. If a voltage problem is detected, the ESC continuously sounds 2 beeps with a 1 second pause (xx-xx-xx). Power OFF the ESC and ensure the connections are secure and that the battery power is not too low for safe operation.
2. Radio Connection: The ESC checks radio signal input when it is powered ON. If a problem is detected, the ESC continuously sounds 1 beep with a 2 second pause (x–x–x). Power OFF the ESC and ensure the radio system is
   operating correctly.

NOTICE: Always disconnect the battery from the ESC after operating your vehicle. The ESC’s switch only controls power to the receiver and servos. The ESC will continue to draw current when connected to the battery, resulting in possible damage to the battery through over-discharge.

BODY PAINTING PROCEDURE

The included body will come with secondary parts of the body screened with color. Choose a color to paint as the main color of the body. Ensure to use polycarbonate paint.

1. Clean the inside of the body shell using a small amount of water and dish soap. Thoroughly rinse and dry the body shell with a cloth towel.
   Tip: Do not use paper towels.

2. Paint the inside of the body shell.

3. Once the paint is completely dry, remove the over-spray film from the outside of the body.

4. Apply additional stickers to customize the body.

ESC CALIBRATION PROCEDURE

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

3. Li-Po Cells
   Allows the ESC to automatically detect or manually set the number of cells in your Li-Po battery back.

4. Cutoff Voltage
   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).

5. BEC Voltage
   It supports 6.0V/7.4V adjustable. 6.0V is applicable to common servo. If use high-voltage servo, set to higher voltage according to voltage marking of servo.
   Note:

6. Do not set the BEC voltage above the maximum operating voltage of the servo, as this may damage the servo or even the ESC.

7. Due to the characteristics of the BEC circuit, there is a voltage difference between the BEC output voltage and the input voltage,when the BEC voltage is set to 7.4V and 2S Lipo is used,the BEC cannot stably output 7.4V (will decrease as the battery voltage decreases).Therefore,it is recommended to use 7.4V BEC when matching with 3S Lipo and above.

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

9. 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.

10. Initial Throttle Force
    It also called as minimum throttle force. You can set it according to wheel tire and traction. If the ground is slippery, please set a small throttle force.

11. PMW Drive Frequency
    The acceleration will be more aggressive at the initial stage when the drive frequency is low; a higher drive frequency is smoother but this will create more heat to the ESC. If set this item to “Customized”, then the PWM frequency can be adjusted to a variable value (which ranges from 2K to 32K) at any 0-100%throttle input, Please choose the frequencies as per the actual test results of your vehicles.

12. 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.

13. 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.

14. Brake Frequency
    The brake force will be larger if the frequency is low; you will get a smoother brake force when the value is higher, please choose the frequencies as per the actual test results of your vehicles.

15. Turbo Timing
    This item is adjustable from 0 degree to 48 degrees, the corresponding turbo timing (you set) will initiate at full throttle. It’s usually activated on long straightaway and makes the motor unleash its maximum potential.

16. Turbo Delay
    When “TURBO DELAY” is set to “INSTANT”, the Turbo Timing will be activated right after the throttle trigger is moved to the full throttle position. When other value(s) is applied, you will need to hold the throttle trigger at the full throttle position (as you set) till the Turbo Timing initiates.

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.

SPEKTRUM™ FIRMA™ 2200KV 4-POLE BRUSHLESS MOTOR

PRECAUTIONS

• Never touch moving parts.
• Never disassemble while the batteries are installed.
• Always let parts cool before touching.
• Rated for up to 4S batteries.

GEARING
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 “overgear” 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.

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).

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 motor mounting screws after ensuring proper gear mesh.
