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, 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.
ENGLISH
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.
• 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 waterdisplacing 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.

AVC® – ACTIVE VEHICLE CONTROL
The Spektrum SRS4220 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 SRS4220 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 SRS4220 receiver. Do not use
analog servos as they will reduce the performance of the system and may cause
overheating.

BINDING
Binding is the process of programming the receiver to recognize the GUID
(Globally Unique Identifier) code of a single specific transmitter. When areceiver
is bound to atransmitter/model memory, the receiver will only respond to that
specific transmitter/model memory.
Your Spektrum DX2E comes prebound to the vehicle. If you need to
rebind or calibrate, follow the instructions below.
1. With the vehicle on a flat, level surface, 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 flashes, 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 flashes. The transmitter
and receiver are linked when the orange LED is solid.
AVC® SENSITIVITY
The AVC/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 AVC/ST RATE knob counter-clockwise to
reduce the sensitivity.
Turn the AVC/ST RATE knob clockwise to increase the
sensitivity.
IMPORTANT: The AVC/ST RATE knob will only adjust

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.
ENGLISH
• 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 discharged 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.
IMPORTANT: Keep wires away from all moving parts.
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 battery packs with a higher mAh rating.

PRECAUTIONS
• Never touch moving parts.
• Never disassemble while the batteries are installed.
ENGLISH
• Always let parts cool before touching.
GEARING
Your vehicle has been equipped with the optimal gearing for the stock platform.
It offers an ideal balance between speed, power and efficiency. Should you
decide to customize your vehicle with optional batteries or motors, it may be
necessary for you to change the pinion or spur gear.
Installing a pinion gear with fewer teeth or a spur gear with more teeth will provide greater torque but will reduce top speed. Likewise, a pinion gear with more
teeth or a spur gear with fewer 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.
CHANGING THE PINION GEAR/GEAR RATIO
1. Unscrew the gear cover screw and remove the gear cover.
2. Loosen the motor screws and slide the motor over.
3. Place the new pinion on the end of the motor shaft so the set screw is
located over the flat on the shaft.
4. Position it so the teeth line up with the spur gear and secure the pinion by
tightening the set screw.
5. Set the gear mesh.
6. Reinstall the gear cover.
SETTING THE GEAR MESH
The gear mesh has already been set at the factory. Setting it is only necessary
when changing motors or gears.
Proper gear mesh (how gear teeth meet) is important to the performance of the
vehicle. When the gear mesh is too loose, the spur gear could be damaged by
the pinion gear of the motor. If the mesh is too tight, speed could be limited and
the motor and ESC will overheat.
1. Unscrew the gear cover screw and remove the gear cover.
2. Loosen the motor screws and slide the motor over.
TIP: The bottom motor screw can be accessed from the bottom of the vehicle.
3. Put a small piece of paper between the pinion and spur gears.
4. Push the gears together while tightening the motor screws.
5. Remove the paper. Check the mesh at 3–5 different locations around the
spur gear for a small amount of movement.
6. Reinstall the gear cover.
TIP: Stock gearing for the vehicle is 50/13. Optional 11t, 12t and 14t pinion
gears are available.
rIdE hEIghT
Set the vehicle on a flat surface and turn the threaded collars on the shocks evenly so both the front and rear suspension arms are level.

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 NiMH 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 (2.6x2=5.2).
4. Bec Voltage
Select either 6 or 8.4 V to run the receiver and servos.
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. Start Mode (Punch)
Sets the initial throttle punch when the car accelerates. Level 1 gives a very
soft initial acceleration and level 5 gives a stronger initial acceleration.
