DRIVING PRECAUTIONS
• Maintain sight of the vehicle at all times.
• Routinely inspect the vehicle for loose wheel hardware.
• Routinely 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. If the receiver loses power,
you will lose control of the vehicle. Damage due to an over-discharged Li-Po battery is
not covered under warranty.
CAUTION: Do not discharge a Li-Po battery below 3V per cell. Batteries dis-
charged to a voltage lower than the lowest approved voltage may become damaged,
resulting in loss of performance and potential fire when batteries are charged.
• Do not apply forward or reverse throttle 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 before driving the vehicle again.
BEFORE RUNNING YOUR VEHICLE
1. Break in the differential. While holding the chassis with only the left rear tire firmly on the
ground, give the vehicle about 1/8 throttle for 30 seconds. The right rear tire should spin
freely during this time. Do this with only the right rear tire firmly on the ground, allowing
the left 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 vehicle to handle poorly.Set the ride height.
3. Set the ride height of your truck with all components installed so that the bottom of the
chassis is 29.5mm from the ground in the front and 29mm in the rear by adjusting the
shock collars.
4. Set the camber. Adjusting the camber tie rod length changes the camber.
Set the front tires to have 1 degree of negative camber at ride height.
Set the rear tires to have 1.5 degrees of negative camber at ride height.
5. Set the front toe-in. Adjust the steering tie rods so that when the servo is centered on the
transmitter, the front tires are both pointing straight.
6. Charge a battery pack. Always charge the battery pack as per the battery and/or
charger manufacturers’ instructions.
7. Adjust the electronics speed control. Follow the instructions to setup and adjust
the speed control for your XXX-SCT / XXX-SCB RTR.
8. Set the transmitter steering trim. Follow the instructions to set the steering trim/subtrim
so that the vehicle drives straight with no input to the steering.
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. The vehicle and receiver MUST remain motionless for at least 2 seconds.
6. Re-install the body on the vehicle.
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.
DISABLING THE STABILITY ASSIST FUNCTION
If you participate in organized racing, you may be required to turn Stability Assist off.
To turn Stability Assist off:
1. Insert a Bind Plug in the BIND port on the receiver.
2. Insert a second Bing Plug in the DISABLE port on the receiver.
3. Connect a fully charged battery pack to the ESC.
4. Power on the ESC. The orange LED flashes, indicating the receiver is in bind mode.
5. Center the ST TRIM and TH TRIM dials on the transmitter.
6. Press and hold the BIND button while powering on the transmitter.
7. Release the BIND button when the orange LED slowly flashes. The transmitter and receiver
are linked when the orange LED is solid.
8. Pull the transmitter trigger to Full Throttle.
9. Push the transmitter trigger to Full Brake, then return the trigger to center.
10. Turn the transmitter steering wheel to Full Right.
11. Turn the transmitter steering wheel to Full Left, then return the steering wheel to center.
The orange LED flashes once.
12. Remove the Bind Plugs, then power off the receiver to save the settings.
13. Power off the transmitter.
IMPORTANT: You must calibrate the receiver each time it is placed in bind mode.
To activate AVC, see the steps in "Calibrating the Receiver".
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).
TUNING, ADJUSTING &
MAINTAINING YOUR 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.
• Clean and oil all wheel bearings.
• 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 the 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.
• Power ON the transmitter. If the green LED is dim or off, replace the AA batteries
in your transmitter.
• Check the spur gear and pinion gear for wear.
CHANGING THE TRAVEL ADJUST SETTINGS
1. Hold the trigger in the full brake position while powering on the transmitter. The LED
flashes rapidly, indicating the programming mode is active.
2. Throttle End Point: Continue holding full throttle. Turn the TH TRIM knob to adjust
the full throttle end point.
3. Brake End Point: Hold the trigger in the full brake position. Turn the TH TRIM knob
to adjust the full brake end point. Return the trigger to the center position.
4. Left Steering End Point: Hold the steering wheel in the full left position. Turn
the ST TRIM knob to adjust the left end point.
5. Right Steering End Point: Hold the steering wheel in the full right position. Turn the ST
TRIM knob to adjust the right end point. Return the steering wheel to the center position.
6. Power off the transmitter to save the travel adjust settings.
The minimum Travel is 75%, and the Maximum travel is 150%.
IMPORTANT: If the travel is changed on the DX2E, you must rebind and calibrate
the SRS4200.
SERVICE/REPAIR
RADIO/SPEED CONTROL & MOTOR
If any problems other than those covered in the troubleshooting section arise, please
call the appropriate electronics service department. 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.
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.
SRS4200 STABILITY ASSIST RECEIVER
AVC – ACTIVE VEHICLE CONTROL
The Spektrum SRS4200 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 SRS4200 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 SRS4200 receiver. Using analog servos
will reduce the performance of the system and may cause analog servos to overheat.
