new radio system prior to operation to ensure the safest and
most enjoyable experience.
• Your model can cause serious damage or injury so please use caution and courtesy when operating your model.
• Do not expose the radio system to water or excessive moisture.
• As a safety precaution, perform all transmitter and receiver adjustments with the vehicle’s wheels off the ground. This ensures
the complete control over the vehicle at all times during adjustments.
• Ensure your batteries (both transmitter and vehicle) have been properly charged for use with your model.
• Keep track of the time the system is in use so you will know how long you can safely operate the transmitter batteries.
• Check all servos and electrical connections prior to each run.
• Do not operate your model near traffic, bystanders, parking areas, or any other area that could result in injury to people or dam-
age to property.
• If at any time during the operation of your model you observe any erratic or abnormal behavior of your model, immediately stop
operation and bring the mode to a safe stop in a safe location to diagnose the problem.
• Always power on your transmitter before turning your vehicle on.
• If you have little or no experience operating R/C models, we strongly recommend you seek the assistance of your local hobby
dealer.
R/C models are an extremely fun hobby, but safety should never be ignored or taken lightly. Always take caution when operating

Binding the Transmitter and Receiver:
The process of allowing communication to occur between a 2.4GHz transmitter and receiver is called “binding” (sometimes referred
to as “matching” or “pairing”). The radio system included with your product comes pre-configured and bound from the factory. In
the event your system loses binding, one of the components has been replaced, you will need to bind the transmitter and receiver.
Follow the below steps for binding your radio system. Always ensure both transmitter and receiver batteries are fully charged or new
when performing this process for best results.
NOTE: AS A SAFETY PRECAUTION, PERFORM THE BINDING PROCESS WITH THE VEHICLE’S WHEELS OFF THE GROUND.
1. With the transmitter in close proximity but not closer than 1ft to the receiver, turn on the transmitter first, then the vehicle. The
LED on the receiver will blink, indicating that the receiver is not bound to a transmitter that is on.
2. With the transmitter OFF, hold the REV/BIND button and turn the power ON to put the transmitter into binding mode.
3. Push the button on the receiver once, the LED will start to blink faster indicating it is searching for a transmitter to bind with.
The transmitter will automatically search and bind to the receiver. This may take up to 10 seconds.
4. Once the transmitter and receiver are bound together, the receiver’s LED will turn solid red. If the receiver’s LED does not turn
solid red, turn off both the transmitter and receiver and repeat steps 1-2.
5. Once binding is complete, turn the power off and back on to both the transmitter and re-
ceiver.
6. Ensure normal operation of throttle and steering.
a. If binding to a different vehicle you may need to reverse the steering channel on your
transmitter to work properly.
7. If you experience anything other than normal operation, repeat the process.
2.4 GHz Fail-Safe Adjustment:
NOTE: AS A SAFETY PRECAUTION, PERFORM THE FAIL-SAFE ADJUSTMENTS WITH THE VE-
HICLE’S WHEELS OFF THE GROUND.
1. Turn the transmitter and receiver ON and move the throttle trigger to the desired position.
2. Press the Fail-Safe button for 5 seconds to program the throttle Fail-Safe setting.It is recommended and common to set the
throttle Fail-Safe as Full Brake, i.e. the throttle trigger is pressed completely forward applying full brakes. This ensures that if the
receiver cannot receive a signal from the transmitter, the servos or ESC will default to full brake causing the vehicle to stop.
a. NOTE: WITH REVERSE MODE ACTIVE IN THE ESC, THE VEHICLE MAY GO INTO REVERSE THROTTLE INSTEAD OF BRAKE
WHEN THE TRIGGER IS PRESSED FORWARD. THIS IS THE CORRECT BEHAVIOUR AND SETTING POSITION. TO PREVENT
WHEELS FROM TURING LIKE THIS, SIMPLY APPLY A LITTLE FORWARD THROTTLE, THEN FULL BRAKES, THEN CON-
TINUE WITH THE FAIL-SAFE SETTING PROCEDURE.
3. To test the Fail-Safe settings, turn the transmitter off while the receiver is on. The servo/ESC will default to its programmed
positions and the motor should not spin (assuming you have set the fail-safe to full brake).

Receiver, ESC and Servo Connections:
1. Channel 1: Steering Servo
2. Channel 2: ESC (Throttle/Brake)
Note: An easy way to remember this is 1 to turn, 2 to burn
( as in burn-out ).
Digital Trim Settings:
• Steering Trim
› Press the “ST+” or “ST-“ button to adjust the
neutral position of the steering. A long “beep” will
sound
› Once the trim setting reaches the limit, a long steady “beep” will sound
» Depending on your servo configuration, “ST+” or “ST-“ will move the servo either left or right. Use either “ST+” or ST-“
to ensure the vehicle can track straight with no steering input
• Throttle Trim
› Press the “TH+” or “TH-“ button to adjust the neutral position of the throttle. A long beep will sound
› Once the value reaches the limit, a long steady “beep” will sound
» The throttle should be trimmed so the vehicle is stationary when no throttle input is applied
Transmitter Model Backup:
The data for every function and model programmed to the transmitter is stored in a memory chip that does not require battery
backup. The transmitter model data is automatically backed up, and is not lost during battery replacement.
Channel Reverse (REV):
The channel reverse function reverses the direction of operation of the servos or ESC’s relative to the transmitter steering and
throttle inputs. This function would be used if, for example, turning the transmitter steering wheel right resulted in the model turning
left and vice versa. Some ESC’s require that the throttle channel be reversed in order to program them properly.
NOTE: AS A SAFETY PRECAUTION, PERFORM THE CHANNEL REVERSE ADJUSTMENTS WITH THE MOTOR UNPLUGGED FROM
THE ESC (CAUTION: DO NOT ALLOW THE WIRES TO TOUCH AFTER BEING DISCONNECTED WHILE PERFORMING THIS SETUP
PROCEDURE) AND THE WHEELS OFF THE GROUND.
• Steering Reverse:
› Turn the steering wheel completely to the left (or right) and press the “REV” button for at least 2 seconds to reverse the
Steering (ST) channel.
› The transmitter will beep once for confirmation.
• Throttle Reverse:
› Pull the throttle trigger completely to full throttle (or push forward for full brake) and press the “REV” button for at least 2
seconds to reverse the Throttle (TH) channel.
› The transmitter will beep once for confirmation.
Steering Dual-Rate (ST D/R):
Steering dual-rate allows on-the-fly end point adjustments to both sides (left and right) of the steering servo.
• The default value is 100% of the maximum servo travel. The dual-rate can be set from 20% to 100%.
› To increase the dual-rate, press the “DR+” button.
› To decrease the dual-rate, press the “DR-“ button.
End Point Adjustment:
• Steering End Point Adjustment (EPA)
› Use this function to adjust the left and/or right steering angle relative to the steering wheel position.
›CAUTION: BE CAREFUL TO NOT OVER-EXTEND THE STEERING THROW AS IT CAN CAUSE YOUR SERVO TO OVER-WORK
AND OVER-HEAT.
› Steering-Left Side Adjustment:
» Turn the steering wheel completely to the left and use the “ST+” or “ST-“ buttons to adjust the steering angle to the
desired location.
› Steering-Right Side Adjustment:
» Turn the steering wheel completely to the right and use the “ST+” or “ST-“ buttons to adjust the steering angle to the
desired location.
• Throttle and Brake End Point Adjustment (EPA)
› Use this function to adjust throttle and brake travel adjustments.

the desired location.
› Brake Adjustment:
» Push the trigger forward to full brake and use the “TH+” or “TH-“ to adjust the brake end point accordingly.
Power Alarm:
• Idle and Low-Battery Alarm
› When the steering wheel, throttle trigger, or any button is not operated for 10 minutes while the transmitter is on, a slow
beeping alarm will sound to indicate that there has been no action and the power should be turned off and back on to reset
the transmitter alarm.
• Low Battery Voltage Alarm
› If the transmitter battery voltage drops to 4.5V or less, a slow beeping alarm sounds and the power LED light will blink.
Battery Replacement:
WARNING: Do not attempt to charge non-rechargeable batteries
NOTE: Load the four AA batteries in accordance with the polarity marking on the battery holder.
1. Remove the battery cover from the transmitter
2. Remove the old batteries
a. NOTE: Never mix brands or old/new batteries.
b. Always be sure to be responsible and protect the environment when disposing batteries. Most local hobby dealers provide a
FREE battery disposal service.
3. Insert the four new AA batteries according to the polarity markings on the battery holder.
a. If using rechargeable batteries, be sure to follow the manufacturer’s care and use instructions.
b. Rechargeable batteries must be removed from transmitter before charging.
4. Replace the battery cover.
5. Slide the Power switch to the ON position. If the voltage is low, the low battery alarm will sound. If the low battery alarm
sounds, check that the batteries are properly inserted and are making sufficient contact.
a. Low Battery Alarm.
i. An alarm will sound if the transmitter voltage drops below 4.5V. This alarm is meant as a safety feature only. The trans-
mitter should not be operated below 4.5V. If the low battery alarm sounds, stop using your model immediately and turn
off both the model’s receiver and the transmitter. Replace the transmitter batteries immediately with fresh AA batteries
to prevent loss of control of your model.
b. Always check the voltage of the transmitter before use.
6. Always be sure to insert the batteries correctly according to the polarity markings, or the transmitter may be damaged.
7. When the transmitter will not be used for 1 week or more, remove the batteries to prevent damage from leaks and corrosion.
Setting the ESC:
The ESC in your Invictus 10MT is pre-programmed to work best with the HRS-3.1 radio system. Use with another radio system
may not provide consistent performance and is not recommended for beginners. For detailed selup information refer to the Reaktor
brushless setup section of this manual.
Standard operation:
• When looking at the face of the transmitter wheel:
› Turning the top of the transmitter wheel to the left from center makes the wheels on the vehicle turn LEFT.
› Turning the top of the transmitter wheel to the right from center makes the wheels on the vehicle turn RIGHT.
» When driving your vehicle for the first time, take care and notice the direction the car turns when driving away from you
vs. towards you. It is best to learn how things work when driving away from your position, but don’t go too far!
• Pulling the transmitter trigger back towards the handle will make the vehicle accelerate forward.
› If instead the tires turn backwards you will need to disconnect and swap 2 wires going to your motor. Any two will do to
reverse the motor direction.
• Pushing the transmitter trigger forward away from the handle will have the following affects depending on the location of the
trigger prior to pushing it forward.
› From a stop at neutral: the vehicle will travel in reverse.
› From pulled back: the vehicle will apply brakes to slow the speed.
» A second push forward of the trigger will apply brakes again
» A second push forward on the trigger will apply reverse throttle.
» WARNING: Causing the vehicle to make quick transitions from forward/reverse motion to the opposite direction
using the throttle control can cause damage to your vehicle and electronics and will void the warranty.

HRS-3.1 STANDARD OPERATION
RADIENT REAKTOR BRUSHLESS ESC OVERVIEW...

Using your transmitter for the first time:
1. Turn the transmitter ON and ensure the LED is lit SOLID and it is not
giving an audible alarm indicating the batteries are supplying adequate
voltage for proper operation.
2. Ensure the battery in your vehicle is secured, charged and plugged in
with proper polarity and turn your vehicle ON.
3. Checking and setting the throttle trim.
a. If the wheels spin in a forward direction when the trigger is in the
neutral position, turn down the trim until the motor stops by pressing
the TH- button, repeatedly if necessary.
b. If the wheels spin in a reverse direction when the trigger is in the
neutral position, turn up the trim until the motor stops by pressing
the TH+ button, repeatedly if necessary.
c. There will be a “dead band” area where the trim can be adjusted
a slight amount in either direction and the wheels will not begin
to move. It is ideal to have the trim set in the middle of this “dead
band”.
4. Setting the steering trim.
a. With your vehicle and transmitter turned on (and properly responding to transmitter inputs), set the vehicle down on the
ground and slowly accelerate in a direction directly away from you. If the vehicle veers slightly either to the left or right,
adjust the steering trim by pressing either the ST- (more left) or ST+ (more right) buttons, repeatedly if necessary.
b. Reset the vehicle position and re-test; adjust the trim as needed until the vehicle travels in a straight line while the transmit-
ter wheel remains at center location (“hands-off”).
The Radient Reaktor series brushless motor and ESC is a great power plant to satisfy your need for speed and performance as an
entry level brushless system. Though the Reaktor system was engineered for value, performance was definitely a factor. We’ve
included some great features for you to help keep your system running in top shape while keeping your battery upgrade path open
since it is compatible with LiPo batteries.
WARNING: ALWAYS ALLOW YOUR MOTOR TO COOL BETWEEN RUNS. EXCESSIVE ACCELERATION AND AGGRESSIVE DRIV-
ING WILL CAUSE YOUR SYSTEM TO GET HOT. EXCERCISE GREAT CARE WHEN HANDLING YOUR VEHICLE AFTER RUNNING TO
AVOID GETTING BURNED.
Some great features of your new ESC include:
• Water-proof and dust-proof. The ESC can work under water for a short
time.
› (Please remove the cooling fan when running car in water, and after
running, please make the ESC clean and then dry it to avoid oxidation
of the copper connectors)
• Specially designed for RC car and truck, with excellent start-up, accelera-
tion and linearity features.
• Compatible with sensorless brushless motors.
• 2 running modes suitable for different applications (“Forward with brake”
mode, “Forward/Backward with brake” mode).
• Proportional ABS brake function with 4 steps of maximum brake force
adjustment, 8 steps of drag-brake force adjustment.
• 4 start modes (“Punch”) from “Soft” to “Very aggressive” to be suitable for
different chassis, tires and tracks.
• Multiple protection features: Low voltage cut-off protection for Lipo or
NiMH battery / Over-heat protection / Throttle signal loss protection / Motor blocked protection.
• Easily programmed with the “SET” button on the ESC or with the LED Program Card.

...RADIENT REAKTOR BRUSHLESS ESC OVERVIEW AND CALIBRATION
Your ESC has been pre-installed at the factory but before using your vehicle each time it is good to double check the wiring for dam-
age or loose connections to ensure everything is in working order before use. Refere to the diagram below to check the connections
of your electronics system. Some brushless motors such as the Reaktor included with your vehicle use only black wires, this is okay.
On sensorless brushless systems the motor will change operat-
ing direction when any two of the motor wires are swapped.
The Reaktor ESC is programmed to communicate
with you, letting you know its status.
• LED Status:
› In normal use, if the throttle trigger is in the neutral
range, neither the red LED nor the green LED light up.
› The red LED lights when the car is run forward or back-
ward and it will flash quickly when the car is braking.
› The green LED lights when the throttle trigger is moved
to the full throttle position.
• Alert Tones:
› Input voltage abnormal alert tone: The ESC begins to
check the input voltage when power on, if it is out of
the normal range, such an alert tone will be emitted:
“beep-beep-, beep-beep-, beep-beep-” (There is 1 sec-
ond time interval between every “beep-beep-” tone).
› Throttle signal abnormal alert tone: When the ESC can’t detect the normal throttle signal, such an alert tone will be emitted:
“beep-, beep-, beep-” (There is 2 seconds time interval between every “beep-” tone).
• Protection Functions:
› Low voltage cut-off protection: If the voltage of a Lipo battery pack is lower than the threshold for 2 seconds, the ESC will
cut of the output power. Please note that the ESC cannot be restarted if the voltage of each Lipo cell is lower than 3.5V.
» For NiMH battery packs, if the voltage of the whole NiMH battery pack is higher than 9.0V but lower than 12V, it will be
considered as a 3S Lipo; If it is lower than 9.0V, it will be considered as a 2S Lipo. For example, if the NiMH battery pack
is 8.0V, and the threshold is set to 2.6V/Cell, it is considered as a 2S Lipo, and the low-voltage cut-off threshold for this
NiMH battery pack is 2.6*2=5.2V.
› Over-heat protection: When the temperature of the ESC is over 105 degrees Celcius for 5 seconds, the ESC will cut off the
output power.
› Throttle signal loss protection: The ESC will cut off the
output power if the throttle signal is lost for 0.2 second.
Throttle range calibration:
Hold your transmitter approx 1ft away while setting.
1. Turn Transmitter ON first (transmitter should alwasy be on if
ESC is ON.
2. Ensure your Throttle channel (Ch. 2) on your transmitter is
set to “Reverse”.
3. Adjust both Throttle and Reverse/Brake EPA settings to
100%.
4. With the ESC OFF, press and hold the Set button near the
switch and turn the ESC ON to enter setup mode. Release
the button as soon as the LED begins to flash.
5. Without touching the trigger, press button to set the neutral
position, GREEN LED will flash 1 time.
6. Pull/hold full throttle, press the button again, release the
trigger, GREEN LED will flash 2 times.
7. Push/hold full brake/reverse, press the button again, GREEN
LED will flash 3 times. Release trigger.
8. Switch ESC OFF and back ON to complete setup.
9. Check the ESC operation to ensure forward throttle is actu-
ally forward, if not, switch any two of the motor wires and
re-check. Then repeat steps 3-8.

Programming your ESC:
The Radient Reaktor is a programmable ESC. Although the default settings should work well for most users, these settings exist so
that you can fine tune the performance of your ESC to your experience and components. It’s various programmable parameters can
be adjusted either by interfacing with the ESC directly button presses and counting LED flashes, or via the optional Reaktor Program
Box (RDNA0031) which includes a digital readout of the settings for easier interpretation and faster setup. There are 6 program-
mable items for your consideration, below are descriptions of each Item and following is the table and programming instructions for
choosing your settings should you choose to change from default (highlighted in BOLD text).
NOTE: The most important of these settings is the Low Voltage Cut-Off Threshold (Item 3). Please
read the description and usage scenarios below to better understand how to use this feature.
Item 1: Running Mode:
1. Forward/Brake: This setting is considered as “Race” mode where the reverse function is disabled.
2. Forward/Reverse-Brake: This setting is useful for normal operation since it allows for using reverse throttle to back out of a
stuck situation.
a. WARNING: switching from REVERSE to FORWARD throttle position quickly will cause excess load on the electronics
and drivetrain of your vehcile. It is recommended to come to a stop before changing REVERSE/FORWARD direction.
Item 2: Drag Brake Force (Automatic Brake):
1. 0%: This setting allows the vehicle to continue to roll after letting off throttle without applying automatic-brake
2. 5%: Adding some drag brake will make the vehicle a little easier to control, especially when driving on a closed circuit type
course, helping you to slow down and make turns easeir.
3. 10%: Add more until you find the right balance of assistance with slowing down while still being able to maintain good corner
speed without upsetting the vehicle.
4. 15%
5. 20%
6. 25%
7. 30%
8. 40%
Item 3: Low Voltage Cut-Off (LVC) Threshold:
The Reaktor ESC has 6 built in LVC options. It is essential that you use the proper LVC setting for the type of battery that your are
useing to achieve the optimal performance and safest operation from your ESC/Motor/Battery. This setting should be chosen based
on the number and type of cells you are using. For LiPo batteries we recommend setting LVC to #5, using a setting lower than this
may cause over discharge of some batteries and cause damage to your battery, which could lead to a fire.
1. No Protection: ONLY to be used with NiMH or NiCd type batteries. Since your vehicle comes equipped with an 8 cell NiMH bat-
tery, we have set this mode as the default. The ESC will run as long as possible, draining all possible energy from the batteries
and evenutally your vehicle will cease to function poperly.
a. When you notice the operation of your vehicle change, it is time to STOP running and re-charge your battery.
b. If you are running your vehicle and notice a sudden decrease in power, your ESC has detected battery voltage that is lower
than what should be safely run without causing damage to your battery or electronic equipment. If you are using NiMH bat-
teries while this happens and you have only been running for a very short time, it is very likely that you are mistakenly using
one of the below LVC modes.
2. 2.6V/Cell: This setting will cause the ESC to enter LVC protection mode when the battery voltage is calculated at the selected
voltage or less for more than 2 seconds. Since the setting is “per cell” this means that if you are running a 2 cell battery, the
voltage protection will activate relative to 2 x 2.6V = 5.2V. This setting is primarily for use with LiFe type batteries as the lower
end of LVC settings. DO NOT USE THIS SETTING WITH LIPO BATTERIES.
3. 2.8V/Cell: This setting would be the starting point for using LiFe type batteries and is not recommended for LiPo batteries.
4. 3.0V/Cell: This setting is only recommended for use with extremely high quality and highly durable LiPo batteries suitable for
competition racing. Using a setting this low with a LiPo battery may cause excessive “wear and tear” on your batteries, shorten-
ing their lifespan.
5. 3.2V/Cell: This setting is recommended as the default for running average grade LiPo batteries. If your batteries are relatively old
it is recommended to use setting 6 instead.
6. 3.4V/Cell: This setting can be used with any LiPo battery and will provide the “safest” discharge level for your batteries however
some lower quality batteries do not sustain their voltage under heavy load and will cause premature LVC activation. Starting
here is a good choice if you are unsure or just want to be extra cautious.
Item 4: Start Mode/Punch (Higher value is more aggressive):
The Reaktor ESC has 4 “punch” profiles that allow you to tune the initial power output of the ESC to suit your driving, vehicle, and

...REAKTOR ESC PROGRAMMING CONTINUED...

BRUSHLESS POWERED
MONSTER TRUCK
the surface. You will typically want a lower punch setting when the surface has less traction. To get the optimal performance out of
LiPo batteries, on high traction sufaces, setting 4 is recommended.
1. Level 1 (70%): This setting will provide the smoothest throttle feel and least wheel spin.
2. Level 2 (80%)
3. Level 3 (90%): This is the highest setting that should be used with high performance NiMH batteries such as those included
with your vehicle.
4. Level 4 (100%): This setting is recommended for use with LiPo batteries only and allows you to get the maximum acceleration
from your power system. Choosing a setting higher than #3 for use with NiMH batteries will cause inconsistent operation of your
ESC, including possible momentary power loss.
Item 5: Maximum Brake Force:
The Reaktor ESC has 4 maximum brake force settings allwowing you to tune your brakes for different driving surfaces. This setting
works in conjunction with the brake EPA setting on your transmitter which can still be used to fine tune the braking force, however
this setting affects the initial brake force also. Since your vehicle is using a high performance brushless motor which has great brak-
ing efficiency already, we have reduced the setting to #3. On some surfaces you may still find this setting to be too high and find
that under heavy braking with 4wd vehicles the rear tires may come off the ground. This is a very unstable situation and should be
avoided at all costs. If this happnes, reduce the maximum braking force to a lower setting. If however you are unable to stop and the
lack of deceleration is not due to wheel slipping, you can increase the braking force.
WARNING: Be sure to check your maximum brake settings by driving from full throttle to full hard brake in an open area.
If the rear tires come off the ground causing a front flip, the vehicle will tumble out of control and could cause personal or
property damage.
1. 25%: This is the lowest setting and should only be used when driving with slow motors and on loose (low traction) surfaces.
2. 50%: It is not recommended to go below this setting on asphault surfaces as the stopping power may not be enough to safely
slow your vehicle.
3. 75%: This is the default setting we feel will provide you the best starting point for many different levels of tration on various sur-
faces. Remember it is extremely important to only drive a vehicle as fast as you can safely stop it. If the vehicle hits something
or someone it can cuase serious injury.
4. 100%: This setting is only recommended if you are running a slotted type motor, running this with a slotless style motor com-
bined with a 4wd vehicle will likely cause front flips thus a loss of control of your vehicle.
Reset to Factory Defaults:
At any time when the throttle is located in neutral zone (except in the throttle calibration or programming mode), hold the “SET” key
for over 3 seconds, the red LED and green LED will flash at the same time , which means each programmable item has be reset to
its default value.
Audible/Visual Programming Alerts:
In dirty conditions or with various installations scenarios, visibility of the LED’s may be obstructed. To assist with setting the ESC
parameters you will also be able to hear audible beeps from the motor that will indicate the value of flashes the LED is transmitting.
To help interpret the beeps and flashes we use a long time flash and long “Beep---” tone to represent number “5”, so it is easy to
identify the higher quantity of flashes/beeps. This applies to both the programming parameter selection and also the value of each
programmable item.
• For example, if the LED flashes as the following:
› “A long time flash” (Motor sounds “B---”) = the No. 5 item
› “A long time flash + a short time flash” (Motor sounds “B---B”) = the No. 6 item
› “A long time flash + 2 short times flash” (Motor sounds “B---BB”) = the No. 7 item
› “A long time flash + 3 short times flash” (Motor sounds “B---BBB”) = the No. 8 item
› “A long time flash + 4 short times flash” (Motor sounds “B---BBBB”) = the No. 9 item.

OPTIONAL ACCESSORIES FOR YOUR REAKTOR BRUSHLESS SYSTEM
1. To assist with programming your ESC we offer an LED based program box that when connected will give a digital readout of the
current Item being programmed and the value. It will also allow you to modify these settings right on the box. You can purchase
this program box at your local hobby dealer as part number RDNA0032. The program box communicates with the ESC through
the fan port. You must disconnect the fan and plug in the program box. Simply plug in the program box and program with normal
sequence but using box instead of counting flashes and beeps. Remember to plug the fan back in when you are done.
NOTE: If you are planning to run in a lot of water, it is recommended to disconnect the fan from the
ESC. Running the fan in water will cause excess load on the fan and ESC and may cause permanent
damage to the ESC and fan.

BRUSHLESS POWERED
MONSTER TRUCK
The Invictus 10MT has been engineered with some available tuning options listed here for reference. The default configuration has
been chosen to provide what we feel is the most enjoyable experience for most operating conditions. However we do encourage
experimentation and testing as that’s where the real fun begins!
Ride height adjustment: It is possible to adjust the ride height of your Invictus 10MT by installing and or removing adjustment
clips located directly above the shock springs.
• Adding more clips will raise the ride height of the vehicle and if done excessively may decrease stability.
• Removing clips will lower the ride height and may cause the chassis to drag on the ground.
• It is ideal to have the drive shafts above level but still allow the shocks to extend when you lift the truck while the vehicle is sit-
ting on a flat surface with the body installed. Add or remove clips to achieve the desired ride height.
Upper Shock Position: There are two shock installation locations for the top mounting location of the shock towers. The de-
fault position is outside (located farther from the centerline of the chassis). Moving the shock mounting location to the inner location
will result in a slightly less responsive feel on the front or rear of the vehicle but it will be a little more stable.

GENERAL CARE AND MAINTENANCE...

General Care:
• Always use clean, dry cloth or soft bristle brush to clean your equipment.
• Never use chemical cleansers to avoid damage to the sensitive electronics and plastics.
Maintenance:
We want you to enjoy your product to its fullest potential. For this to happen it is important to keep your product clean and properly
maintained. Lack of cleaning and maintenance can cause component failure. For best and continued performance from your product
it is recommended to briefly inspect your product for damage every few runs. Typically, a good time to do this is when changing the
battery or while it is charging. If a problem is discovered, stop use immediately and perform repairs or seek assistance. Continued
use of failed components can cause more unnecessary damage to your product. Always remember to use genuine replacement
parts from your local hobby dealer. Below is a list of items for inspection. Inspection should not be limited to this list; if you notice
any problem, listed or not, it is recommended to give it proper attention.
1. Electronics: Although the ESC and servo included in your vehicle are waterproof the receiver is not, however it is contained in a
water resistant box. It is recommended that you avoid submersion of the vehicle however light running in puddles and light rain
should not be damaging. If you plan to run for extended periods of time in light or heavy rain It is recommended to secure the
receiver in an additional waterproof membrane. Since the Helion HRS-3.1 receiver is a micro size receiver, fitting it into a balloon
is fairly easy. Simply insert the receiver with connected wiring into a balloon and secure the balloon around the wires with an
additional rubber band as close to the receiver as possible, allowing the most exposure of the antenna as possible.
2. Antenna: A properly installed and undamaged antenna is critical to achieve full operating range with your radio system.
a. Inspect any exposed antenna for cuts or abrasions.
b. Ensure there are no kinks in the antenna or antenna tube.
c. Never fold the end of the antenna over the tube, this will reduce the range and damage the antenna.
d. Ensure the antenna is not being pinched by the set screw that holds the antenna tube in place.
3. Gears: Periodically remove the gear cover to clearly inspect the gears and ensure there is no debris in the gear compartment.
a. Proper gear mesh setting is crucial for proper operation and life of gears in your product. It is important to have the pinion
gear (attached to motor) as close to the spur gear (attached to drive shaft) as possible yet while providing a minimal amount
of backlash. Backlash is the rotation one gear has to make before contacting the other. Having the gear mesh set too tight
will cause excess load on the electrical components and may cause premature failure. Having gear mesh set too loose will
cause excess wear and possible skipping of teeth during operation thus causing excess wear and premature failure.
b. Checking the gear mesh.
i. Remove the spur gear cover.
ii. Check how much movement is allowed of the spur gear before the pinion gear moves (this is purely by feel, not visual).
Check this movement in multiple places by rotating the spur gear approximately 1/6 rotation and checking again.
iii. If the spur gear is allowed to move more than a very small amount, or if it there is no backlash, the gear mesh must be
adjusted. If there is a lot of movement, it is recommended to attempt to tighten the mesh. Attempted adjustment should
only improve the situation; if the mesh was correct to begin with, you will know what that feels like, and if it wasn’t cor-
rect, it will be when you are done after following these procedures.
iv. Setting the gear mesh.
01). Loosen the top screw securing the motor plate to the motor mount, only enough to allow the plate to move.
Check and ensure there is no debris in the gears affecting the mesh.
02). Slide the top of the motor plate away from the center of the chassis, insert a strip of notebook paper between the
pinion and spur gear, then slide the motor plate back until there is no backlash. You will have to push relatively
hard to ensure the paper is pressed all the way into the teeth.
Lower Shock Position: There are two shock installation locations for the lower mounting location of the shocks in the suspen-
sion arm. The default location is inside. Moving the shocks to the outside location will result in a slightly less responsive feel on the
front or rear of the vehicle but become a little more stable. This change will also decrease the vehicle’s articulation and you will no-
tice less body roll. Always check and adjust, if necessary, the ride height of your vehicle after moving the shock mounting locations.
Battery mounting: Your vehicle comes equipped with and default mount setting for a 8-Cell NiMH hump battery. It is also pos-
sible to fit lower cell count NiMH batteries and also 2-3s LiPo batteries (we highly recommend hard cased batteries that resist wear).
Ensure the foam block is in place to keep the battery pack from changing position in the battery tray.
Body Mount Height: The body mounts are capable of vertical adjustment with many height options available. The default set-
ting allows for the lowest body position while maintaining component clearance. Adjust the body mounts to achieve a desired look,
we recommend the lowest possible mounting for best performance.

03). Hold the motor snugly in position while retightening the screw.
04). Rotate the spur gear to feed the paper out of the mesh, re-check the gear mesh and adjust again if necessary.
v. Re-install the spur gear cover.
WARNING: Never operate your vehicle with the spur gear cover removed. Severe injury, damage to electrical components,
and excessive wear and tear on drivetrain may result.
4. Shocks: Periodically inspect the shocks for smooth motion, leaking oil and dirt residue build up around the shaft.
a. Do not allow dirt to build up around the shock shaft and bottom of the shock. Doing so will reduce the life of the shock and
cause a shock to leak oil. Be sure to clean the shocks regularly with a clean and dry soft bristle brush and/or rag.
b. Signs to look out for determining if your shock needs to be maintained or rebuilt.
i. Oil around the shaft means the oil leaked from inside and needs to be replaced.
ii. Persistent oil around the shock shaft or lower portion of the shock typically points to damaged O-rings which will need
replacing. See your local hobby dealer for replacement parts.
iii. Refilling your shocks:
01). Remove shock from vehicle, remove spring and top cap.
02). With shock shaft extended, add oil to top of body (use only 100% silicone oil).
03). Slowly compress the shock shaft 50% of travel using a towel or paper napkin to clean up overflowed oil.
04). Slowly reinstall the shock cap and check for free motion of shock.
05). It is normal for the shock to rebound (with the spring removed) after full compression and release.
iv. Replacing the O-rings:
01). Disassemble shock and remove shaft from the body.
02). Carefully remove lower cap by unscrewing from the shock body.
03). Remove the O-rings and spacer and replace with genuine replacement parts.
04). Re-assemble the shock following the refilling instructions above.
5. Tires and wheels:
a. Inspect the tires to ensure they are properly glued to the wheels. The tires on your vehicle come pre-glued from the factory;
however after running your vehicle it is possible for the glue to come loose in some areas.
i. To reattach the tire to the wheel, use hobby grade Cyanoacrylate (CA) glue and apply small amounts (one drop at a
time) between the tire and wheel. Allow the glue to fully dry before operating your vehicle.
Caution: Follow manufacturer’s warnings and directions when using CA glue. It is always recommended to wear eye pro-
tection when maintaining your vehicle.
ii. When reinstalling tires, use caution when tightening the nuts that secure the wheels to the vehicle. Ensure the wheels
rotate freely after installed but don’t wobble excessively. Over tightening the wheels may cause strain on the electrical
and mechanical components of your vehicle. Operating your vehicle under these conditions will void your warranty.
iii. Taking the above into consideration, leaving wheels too loose can cause them to strip. It is recommended to check that
the wheel nuts are tight every time you run your vehicle.
iv. Tire wear: Consequently running your vehicle will cause the tires to eventually wear out. Be sure to obtain and use
genuine replacement parts from your local hobby dealer when necessary.
6. General wear and tear; be sure to regularly inspect your vehicle and accessories for excess wear and damaged components.
a. Using your vehicle will cause wear and tear which is not covered under warranty yet may necessitate replacement of com-
ponents. Continued operation of your product with worn components may cause excessive wear to other components.
Storage:
• Always store all equipment in a cool dry place when not in use.
• Always disconnect the batteries before storage.
• Never store the battery, vehicle or transmitter in direct sunlight for extended periods of time.
• Never store the transmitter with batteries installed for extended periods of time. Doing so may allow the batteries to leak and
cause permanent damage to the transmitter.
Disposal:
Your product is equipped with NiMH batteries which are considered electronic waste and should never be discarded in standard
garbage containers. Please visit your local hobby dealer (and some hardware stores too) and use the FREE battery disposal center
for proper disposal/recycling. Consult your local city hall for information on recycling other electronic waste.

SAFETY TIPS
TROUBLESHOOTING PROBLEMS

Although great for first time users, Helion RC products are indeed advanced radio controlled vehicles with sensitive electronics and
moving parts capable of causing injury if used improperly. Always use caution and common sense as failure to operate your Helion
RC product in a safe and responsible manner can result in damage to the product or other properties. Therefore this product is not
intended for use or maintenance by children without direct adult supervision. Helion RC and your hobby dealer shall not be liable
for any loss or damages, whether direct, indirect, special, incidental, or consequential, arising from the use, misuse, or abuse of this
product or any product required to operate or maintain it.
• Do not operate your vehicle in rain, electrical, or thunder storms.
• The vehicle should never be turned ON without the transmitter being turned ON.
• Never operate your vehicle when with low transmitter batteries (Indicated by flashing LED on the transmitter).
• Always check for proper radio system operation (steering and throttle) prior to letting go of the vehicle. If the vehicle does not
respond properly to transmitter input, turn the vehicle OFF and inspect all connections and operating environment. Also see the
Troubleshooting guide in this manual.
• Optimal enjoyment and safety will occur in a dry, open environment away from traffic, and cars.
• Always turn off both transmitter and ESC and disconnect the battery from the ESC after use.
• Exercise extreme caution when touching the motor and battery connectors immediately after running your vehicle, they may be
HOT and cause a burn.
• Always allow the motor in your vehicle to cool before using again.
NOTE: Only use genuine replacement or aftermarket parts available from your local hobby dealer to ensure proper opera-
tion of your Helion RC product.
Before contacting customer support, recall that this is a hobby grade product intended to be user serviceable.
Please take the time to fully inspect your product for any obvious causes to the issues you are experiencing.
Below are some of the most common issues experienced. Scan the QR code to the right with your smart phone
for quick access to the product support page on our website.
1. Dead transmitter or vehicle batteries will cause the product to malfunction and not work properly. As with
TV remote controls in your home, if the batteries are dead, they don’t work. Start power related trouble-
shooting with fresh batteries in the transmitter and recharged batteries in the vehicle.
2. Connections between the Battery, ESC, and Motor are critical to the performance of the product. Running in various debris may
cause foreign objects to snag on wires, causing connections to come loose. It is a good idea to unplug and reconnect motor and
battery connections when beginning power related troubleshooting.
3. Drivetrain issues can mask themselves as power related. Fully inspect the wheels, driveshafts, and motor for foreign objects
that may have become tangled or wrapped around the spinning parts of the drivetrain. Small objects like fishing line for ex-
ample, can wrap around a drive shaft, overheat and melt due to the friction and cause the entire drivetrain to lock up. Although
a big problem, it can be difficult to see when inspecting. Always remove the wheels from your vehicle when starting drivetrain
related issues.
4. The drivetrain in your vehicle has a covered shaft to protect from debris. We encourage you to inspect the clear cover to en-
sure that items have not been entangled around the shaft causing drag and possible failure. Inspect the holes of your motor for
foreign objects and remove them if present. Inspect around the steering components to ensure no debris are preventing normal
steering operation.
5. Steering can become sluggish once components get dirty or “take a set” after running. Check to ensure the pivot balls on the
steering blocks have a little slop (like backlash) to allow free movement. Also inspect the rod ends of the turnbuckles to ensure
they are properly aligned and not binding. You should be able to grab a turnbuckle with your fingers and rotate it easily.
6. Healthy gears are crucial to a properly functioning vehicle. If you hear your vehicle making very loud noises, you should imme-
diately stop and check the gears for foreign debris. Even a small pebble can get lodged into the teeth of the pinion gear, which
would practically destroy the spur gear in a very short period of time.
