4. Install a Receiver
5. Install a Steering Servo
6. Install a Motor/ESC combo.
7. Install a fully charged battery in the vehicle.
8. Power ON the transmitter and then the vehicle. Always power the transmitter ON before the vehicle and power it OFF after the vehicle has been powered OFF.
9. Check the steering and throttle control directions. Verify that the servos are moving in the correct direction.
10. Drive your vehicle.
11. Perform any necessary maintenance.

INSTALLING THE RECEIVER (NOT INCLUDED)

1. Install servo tape to the receiver.

2. Install the receiver to the chassis.

3. Refer to transmitter/receiver manual for binding instructions.

4. Connect the steering linkage to the ball on the servo arm.

5. Connect the other end of the steering linkage to the ball on steering rack.

6. Connect the servo wire to the steering port on the receiver.
   

INSTALLING THE STEERING SERVO (NOT INCLUDED)

1. Mount the servo SX107 with the output shaft toward the left side of the chassis a as shown in the image below.
   

2. Center the steering servo using a servo checker. If no servo checker is available, the servo can be centered with the radio system. Power on the transmitter and ensure the steering trim is centered. Plug the servo into the receiver. Power on the receiver. The servo should power on and move to center.

3. With the servo centered, install the recommended (LOS311010) servo horn so the ball is 90 degrees as shown in the image below.
   NOTE: The included aluminum servo horn requires a servo with a 20T output gear.
   

INSTALLING THE MOTOR ESC COMBO (NOT INCLUDED)

1. Remove two screws and the gear cover.

2. Install the recommended (DYNS0501) motor. Mount the motor on the center top and bottom holes of the mount.
   

3. Slide the 18T pinion gear on the motor shaft. Match the tooth profile of the pinion gear to the tooth profile of the spur gear, then tighten the pinion gear to the motor shaft. Ensure the set screw for the pinion gear is tightened on to the flat spot on the motor shaft, or the pinion gear will come off. The pinion should be centered to the spur gear as shown in the image below.
   

4. Route the ESC wire down the side guard using the supplied clip to guide the wire to the receiver.
   

5. Route the ON/OFF wire down the side guard using the supplied clip to guide the wire to mount the ON/OFF Switch.
   

6. Install the gear cover.

INSTALLING THE BATTERY AND POWERING ON THE VEHICLE

1. If required, remove the body clips and lift the body.
2. Remove the elastomer strap from the battery posts.
3. Install the fully charged battery in vehicle.
4. Re-secure the elastomer strap.
5. Connect the battery to the ESC/receiver.
6. Ensure the ESC/receiver is powered off.
7. Power on the transmitter.
8. Power on the ESC/receiver.
9. Reinstall the body and the body clips.
   

BINDING

Refer to your transmitter/receiver manual for binding insturctions.

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 Throttle Trim 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 Steering Trim, 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 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 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.

GETTING STARTED

1. Power on the transmitter
   

2. Power on the ESC.

3. Perform a test of the transmitter’s control of the vehicle with the vehicle’s wheels off the ground.

4. Start driving slowly, and, if the vehicle does not go straight, adjust the steering trim 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.

TUNING, ADJUSTING AND MAINTAINING THE VEHICLE

• Examine your vehicle on a regular basis.
• Use a brush to remove dirt and dust.
• Look for damage to the suspension arms and other molded parts.
• Re-glue the tires to the wheels, if necessary.
• Use suitable tools to tighten fasteners.
• Make sure the camber and steering linkages are not bent. Replace any bent linkages.
• Adjust the Toe and Camber settings, if necessary.
• Remove the shocks and inspect them for damage. Rebuild the shocks if oil is leaking.
• Inspect electronics and batteries for exposed wires. Repair exposed wires with shrink-wrap or replace the wire.
• Make sure the ESC and receiver are secure on the chassis. Replace the double sided tape, if necessary.
• Check the spur gear for wear.

SERVICE/REPAIR

RADIO/SPEED CONTROL AND MOTOR

If any problems other than those covered in the troubleshooting section arise, please call the appropriate electronics service department at 877 504 0233. They will be able to give the problem additional specific attention and provide instructions for the solution.

MAINTENANCE

If any questions other than those covered in the troubleshooting or maintenance sections arise, please call the appropriate Horizon product support department at 877 504 0233.

CLEANING

Performance can be hindered if dirt gets in any of the moving suspension parts. Use compressed air, a soft paintbrush, or a toothbrush to remove dust or dirt. Avoid using solvents or chemicals as they can actually wash dirt into the bearings or moving parts, as well as cause damage to the electronics.

SHOCK CLEANING

Oil-filled shocks will require regular maintenance due to the oil breaking down or getting dirty. This maintenance should be performed after about every 3–5 hours of use, depending on the driving conditions.

• Remove the shock from the vehicle.
• Remove the bottom cartridge from the shock body and dispose of fluid.
• Disassemble the shock. Clean thoroughly with a plastic- and electronic-safe degreaser (DYNE50001). Dry parts before assembly.
• Re-assemble the shock and refill the shock body with silicone fluid (22.5 weight recommended, TLR74003).
• Slowly move the shaft and piston up and down to remove air bubbles.
• Move the piston to the midway point of the body and install the bottom cartridge.
• Wipe off any overflowing fluid.

• Re-install the shock on the vehicle.
  RIDE HEIGHT ADJUSTMENT
  Ride height is an adjustment that affects the way the vehicle jumps, turns and goes over bumps. Drop one end of the vehicle from approximately 6 inches (152 mm) in height onto a flat surface. When dropping the front of the vehicle, after the vehicle settles, make sure the front arms are equal and parallel to the flat surface.
  Do the same with the rear to make sure both arms are parallel with the flat surface. Lowering the front ride height increases steering, but decreases traction. Lowering the rear ride height increases traction, but decreases steering.
