WATER-RESISTANT VEHICLE WITH WATERPROOF ELECTRONICS
Your new Horizon Hobby vehicle has been designed and built with a combination of water-
proof 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, how-
ever, 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” sec-
tion 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 manu-
facturer 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.

ACTIVE VEHICLE CONTROL™ (AVC®)
The Spektrum 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 sen-
sitivity value increases the amount of steering control from the transmitter. The 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 AVC receiver. Do not use analog servos as
they willl reduce the performance of the system and may cause overheating.
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 AVC/ST RATE knob counter-clockwise to reduce the sensitivity.
Turn the AVC/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®AVC® receiver. When the transmitter is
bound to a DSM2®/DSMR non AVC receiver, the ST RATE knob controls
the steering dual rate.
AUX CHANNELS
The Aux channels can operate as additional servo channels, or as a power supply for a
personal transponder.
If AVC is active, only 4 channels; Steering, Throttle, AUX3 and AUX4 are operational.The
remaining Aux channels can be used to power a personal transponder or lights.
If AVC is disabled (see DISABLING AVC TECHNOLOGY STABILITY ASSIST FUNCTION), all 6
channels including the Aux channels can operate as servo channels.

BINDING AND CALIBRATING THE RECEIVER
Binding is the process of linking the SR6200A receiver to your Spektrum transmitter. The AVC
features on the receiver can be enabled or disabled during the binding process.
IMPORTANT: You must calibrate the SR6200A receiver each time it is placed in bind mode,
regardless of AVC being enabled or disabled.
Upon initial setup after the first bind, the model must be configured for servo direction, trim
and travel.Then the receiver must be rebound and calibrated to those settings for proper
operation. Center the steering trim and throttle trim on the transmitter before beginning.
1. Press and hold the bind button on the receiver.
2. Power on the receiver. The orange LED flashes, indicating the receiver is in bind mode.
Release the bind button after the orange LED illuminates.
3. Put your transmitter in bind mode. The bind process is complete when the orange LED
on the receiver remains lit. The receiver is now bound to the transmitter but must be
calibrated before it will operate.
4. Pull the transmitter trigger to full throttle, pause, then return the trigger to center.
5. Push the transmitter trigger to full brake, pause, then return the trigger to center.
6. Turn the transmitter steering wheel to full right, pause, then return the wheel to center.
7. Turn the transmitter steering wheel to full left, pause, then return the steering wheel to
center. The orange LED flashes to confirm the settings have been accepted.
8. Turn off the vehicle to complete the binding and calibration process.
CAUTION: When the bind process is complete, the throttle and steering channels
are active. Keep hands and loose objects away from all spinning parts on the vehicle.
IMPORTANT: You must rebind the transmitter and receiver if you:
» Change the servo reversing after binding
» Change the travel after binding
» Change the receiver mounting orientation
DISABLING AVC®TECHNOLOGY STABILITY ASSIST
If you participate in organized racing, you might need to turn off AVC technology. To turn off
AVC technology:
1. Connect power to the receiver and quickly press and release the bind button three times
(within 1.5 seconds).
2. Press and hold the bind button to put the receiver in bind mode. Release the button when
the LED starts to flash rapidly, indicating it is in bind mode.
When the AVC system has been disabled, the LED on the receiver will show three flashes
upon power up, and then remain lit. The receiver is bound and operating normally when the
LED remains illuminated.
TIP: If the AVC feature in the receiver is active and the AVC menu in the transmitter is Inhib-
ited, AVC functions will default to the AUX 1 and AUX 2 operation, and in this scenario,AVC
will not work correctly.
FAILSAFE
In the unlikely event that the radio link is lost during use, the receiver will drive the throttle
channel to the neutral position. If the receiver is powered on prior to turning on the transmit-
ter, the receiver will enter the failsafe mode, driving the throttle channel to the neutral posi-
tion. When the transmitter is turned on, normal control is resumed.
IMPORTANT: Failsafe activates only in the event that signal is lost from the transmitter.
Failsafe will NOT activate in the event that receiver battery power decreases below the recom-
mended minimums or power to the receiver is lost.
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
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.
POWERING ON THE VEHICLE
IMPORTANT: The vehicle MUST remain on a flat, level surface and motionless
for at least 5 seconds.
IMPORTANT: Keep wires away from all moving parts.
1. Center the ST TRIM and TH TRIM dials on the transmitter.
2. Power on the transmitter.
3. Connect the fully charged battery packs to the ESC.
4. Power on the ESC.
BEFORE RUNNING YOUR VEHICLE
1. Check for free suspension movement. All suspension arms and steering components
should move freely. Any binds will cause the vehicle to handle poorly.
2. Charge a battery pack. Always charge the battery pack as per the battery and/or
charger manufacturers’ instructions.
3. Check the wheel nuts to ensure they are not loose.
4. 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.
5. Perform a Control Direction Test.
IMPORTANT: Check for any binding in the drivetrain and confirm that the vehicle moves freely.

LOSI®POLARIS RZR PRO R 1/10 4WD DESERT SXS RTR • INSTRUCTION MANUAL
PERFORMING A CONTROL DIRECTION 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.
CHANGING THE TRAVEL ADJUST SETTINGS
1. Hold the trigger in the full brake position and turn the steering wheel to Full Right 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 DX3, you must rebind and calibrate 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 capac-
ity over time.
Driving the vehicle from a stop to full speed repeatedly will damage the batteries and elec-
tronics 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).
POWERING OFF THE VEHICLE
1. Power off the ESC.
2. Power off the transmitter.
3. Remove and charge the batteries.
IMPORTANT: Keep wires away from all moving parts.
After driving the vehicle, allow the electronics to cool before driving the vehicle again.

AUDIBLE WARNING TONES
1. Input Voltage: The ESC checks the input 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.
ESC CALIBRATION PROCEDURE
Complete the transmitter/receiver binding procedure prior to calibrating the ESC.
1. Set the transmitter throttle channel to 100% travel and center the throttle trim.
2. Connect a battery to the ESC battery lead.
3. Power on the transmitter.
4. Press and hold the SET button while turning on the ESC. Release the SET button when
the red LED begins to flash, indicating the ESC is in calibration mode. The ESC will enter
programming mode if the button is held for more than three seconds.
TIP: The red LED should be flashing when the ESC enters calibration mode. If the green LED
is flashing the ESC has entered programming mode. Power off the ESC and repeat step 4,
releasing the SET button when the red LED begins to flash.
5. With the transmitter throttle trigger at the neutral position, press and release the ESC SET
button. The red LED will stop flashing, the green LED will flash one time and the motor will
make a tone to indicate the neutral position has been accepted.
6. While holding the throttle trigger at the full throttle position, press and release the ESC

LOSI®POLARIS RZR PRO R 1/10 4WD DESERT SXS RTR • INSTRUCTION MANUAL
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 re-
verse, 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 batter-
ies, if the voltage battery pack is higher than 9.0V, it will be treated as a 3-cell Li-Po bat-
tery 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. Punch (Level)
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. Initial Brake Force (minimum brake)
Adjusts the minimum amount of braking power when the brakes engage. The default value
is equal to the drag brake value. A high value can lock the wheels when the brake is used.
8. 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.
9. 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.
The following programmable Items require the optional Digital ESC Program Box:
10.Thermal Protection
Available Items are subject to firmware updates to the ESC and the optional digital
program box.
11.Motor Rotation
Allows you to make this change in the ESC so no wires need to be changed between the
ESC and the motor.
12.Li-Po Cells
Allows the ESC to automatically detect or manually set the number of cells in your Li-Po
battery back.
SPEKTRUM FIRMA 3800KV BRUSHLESS MOTOR
PRECAUTIONS
• Never touch moving parts.
• Never disassemble while the batteries are installed.
• Always let parts cool before touching.
GEARING
Your stock vehicle has been equipped with an 12T pinion for optimal gearing. 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 tempera-
tures 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
The Losi Polaris RZR Pro R uses a motor mount with pre-set gearing.
1. Remove the lower motor mount chassis plate, the motor, and motor mount.
2. Loosen the set screw and remove the installed pinion gear.
3. Install the motor screws corresponding to the number of teeth on the pinion gear.
4. Place the new pinion gear on the end of the motor shaft, so the setscrew is located over
the flat of the shaft.
5. Position the pinion gear so that the teeth line up with the spur gear and secure the pinion
gear by tightening the set screw.
6. Check the gear mesh to ensure that everything spins properly.
SETTING THE GEAR MESH
The motor gearing is set on the motor mount and uses corresponding holes that match the
number of teeth on the pinion gear. 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 pinion gear can damage the spur gear. If the mesh is too tight,
speed could be limited and the motor and ESC will overheat.
IMPORTANT: The included 12T pinion gear is suitable for use with 2S or 3S Li-Po batteries.
NOTICE: For extreme load surfaces (e.g., sand and tall grass), gear down 1–2 teeth on the
pinion gear to minimize the chance of motor and ESC damage.
