Introduction
Select by Helion was born of a quest for the ultimate marriage of performance,
value and innovation. Making any sort of compromise in this respect is
not an easy task, so we’ve done our best not to. We’ve included what we
believe to be the best radio system in its class, the most durable and robust
brushless powerplant that includes proprietary technology, and we’ve added
high performance engineering grade composite plastics with aircraft grade
aluminum and high carbon steel components. We’ve taken a chassis platform
that could have been ok, and we’ve made it great. The individual components
can be seen as capable, over engineered, rened and optimized, but their
specs weren’t chosen on how they perform in isolation. It was their collective
performance that mattered so we made sure the components complemented
each other to achieve perfect synergy in a product that best ts our customers’
needs and expectations. It’s not just about being good, it’s about being Select.

Radient Reaktor120T Brushless System Overview
The Radient Reaktor series brushless motor and ESC is a great power plant
to satisfy your need for speed and performance, not just an entry level
brushless system, your Reaktor system has some of the most advanced
technology in ESC and motor development in the industry today. Here are
some great features we included that help keep your system running in top
shape ensuring maximum enjoyment potential.
CAUTION: ALWAYS ALLOW YOUR MOTOR TO COOL BETWEEN RUNS. EXCESSIVE
ACCELERATION AND AGGRESSIVE DRIVING 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 ESC
• Total System Protection (TSP) is an exclusive technology which protects
your entire system against typical failures experienced and sometimes
caused by new users.
CAUTION: ALTHOUGH TSP HAS BEEN ENGINEERED TO PROVIDE THE MAXIMUM
PROTECTION AVAILABLE TODAY, IT IN NO WAY MAKES FAILING PRODUCT
IMPOSSIBLE. TSP PROVIDES ADDED PROTECTION AGAINST THE MOST COMMON
TYPES OF FAILURES EXPERIENCED AND SOMETIMES INDUCED BY NEW USERS.
• Ready for all weather conditions allowing you to experience the fun of
rain, puddles and snow.
CAUTION: REMOVE THE COOLING FAN WHEN RUNNING IN WATER TO PREVENT
FAN OVERLOAD AND FAILURE. AFTER RUNNING, CLEAN AND THEN DRY THE ESC
AND FAN TO AVOID OXIDATION OF THE COPPER CONNECTORS.
• Specially designed for RC car and truck, with excellent start-up,
acceleration 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.
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 damage or loose
connections to ensure everything is in working order before use. Refer 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 operating direction when any two of the motor wires are swapped.

10
Total System Protection (TSP)
The Reaktor “T” series ESC’s and Motors incorporate the TSP technology. The
TSP system protects against the following failure modes.
• Over-current: Operating your product in very tall grass or in environments
that create a lot of drag in the drivetrain can cause the motor to draw
more current than the ESC is rated to maintain. This incredibly advanced
circuitry is calibrated to sense the current state and predicted state of the
electronics and will shut down the power to the motor to prevent an over-
load condition. The most common causes of an over-current condition are
improper gearing or running in very high drag environments such as tall
grass, wet heavy mud or in situations where damage has occurred to the
drivetrain but gone un-noticed.
• Over-temperature: Exclusive to the Radient Reaktor “T” Series is the
integrated temperature monitoring of both the ESC and the motor. Never
before has a sensorless brushless combo had the technology incorporated
which allows the ESC to monitor the temperature of the motor and enables
the cutting of power to prevent an over-heat melt down of the motor and the
ESC.
CAUTION: MONITORING THE MOTOR’S TEMPERATURE AND FOR THE TSP SYSTEM
TO FUNCTION CORRECTLY REQUIRES THE CONNECTION OF THE SENSOR PORT
(LOCATED IN THE BACK OF THE MOTOR) AND THE SENSOR INPUT ON THE ESC.
The Reaktor ESC is engineered to communicate with you
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 backward and it will ash
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 second
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 selected 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 the set threshold.
• Over-heat protection: When the temperature of the ESC is over 105 degrees
Celsius 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
1. Hold your transmitter approximately 1ft away while calibrating the ESC.
2. Turn Transmitter ON rst (transmitter should ALWAYS be ON if the ESC is
ON.
3. Ensure your Throttle channel (Ch. 2) on your transmitter is set to “Reverse”.
4. Adjust both Throttle and Reverse/Brake EPA settings to 100%.
5. 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 ash.
6. Without touching the trigger, press the button to set the neutral position,
the GREEN LED will ash 1 time.
7. Pull/hold full throttle, press the button again, release the trigger, the
GREEN LED will ash 2 times.
8. Push/hold full brake/reverse, press the button again, the GREEN LED will
ash 3 times. Release trigger.
9. Switch the ESC OFF and back ON to complete setup.
10. Check the ESC operation to ensure forward throttle is actually forward, if
not, switch any two of the motor wires and re-check. Then repeat steps 3-8
if you experience odd behavior.

12
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 ne tune
the performance of your ESC to your experience and components. Its various
programmable parameters can be adjusted either by interfacing with the
ESC directly (button presses and counting LED ashes), or via the optional
Reaktor Program Box which includes a digital readout of the settings for
easier interpretation and faster setup. There are 6 programmable parameters
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 the defaults (highlighted in BOLD text).
CAUTION: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.
Running Mode
Option 1: Forward with Brake. It has forward and brake functions only and is
usually a racing mode.
Option 2: Forward / Reverse with Brake. This mode can be used as for
training and it has “Forward/ Reverse with Brake” mode. Radient adopted the
“DOUBLE-CLICK” method, that is your vehicle only brakes on the 1st time

you push the throttle trigger forward (brake) (1st push). The motor stops
when you quickly release the throttle trigger and then re-push the trigger
quickly (2nd push), only then the vehicle will reverse. The reverse function
will not work if your car does not come to a complete stop.The vehicle only
reverses after the motor stops. This method is for preventing vehicle from
being accidentally reversed.
Lipo Cells
“Auto Calculation” is the default setting. If LiPo batteries are often used with
the same cell count, we would strongly recommend setting this item manually
to avoid the incorrect “calculation” (For instance, the ESC may take a not fully
charged 3S LiPo as a fully charged 2S LiPo) which may cause the low-voltage
cutoff protection to not function ideally
Cutoff Voltage
Sets the voltage at which the ESC lowers or removes power to the motor
in order to either keep the battery at a safe minimum voltage (for LiPo
batteries). The ESC monitors the battery voltage all the time, it will
immediately reduce the power to 50% and cut off the output 10 seconds later
when the voltage goes below the cutoff threshold. The RED LED will ash a
short, single ash that repeats to indicate the low-voltage cutoff protection is
activated. Please set the “Cutoff Voltage” to “Disabled” if you are using NiMH
batteries.
1. Disabled: The ESC does not cut the power off due to low voltage. We do
not recommend using this option when you use any LiPo battery as you
will irreversibly damage the product. You need to select this option when
you are using a NiMH pack.
2. Auto (Low): Low cutoff voltage, difculty to get the LVC Protection
activated, is applicable to batteries with poor discharge capability.
3. Auto (Intermediate): Medium cutoff voltage, prone to getting the LVC
Protection activated, is applicable to batteries with ordinary discharge
capability.
4. Auto (High):High cutoff voltage, very prone to getting the LVC Protection
activated, is applicable to packs with great discharge capability.
WARNING: IF YOU SET THE CUTOFF VOLTAGE TO DISABLED WHEN YOU USE A LIPO
PACK, THEN PLEASE PAY ATTENTION TO THE POWER CHANGE OF YOUR VEHICLE.
IN GENERAL, THE BATTERY VOLTAGE GETS PRETTY LOW WHEN YOUR VEHICLE IS
SEVERELY LOSING POWER, THEN YOU SHOULD STOP USING THAT PACK.
Thermal protection
The ESC will automatically cut off the output with the GREEN LED ashes
when the temperature gets up to the value you’ve previously preset and
activates the ESC Thermal Protection. The output will not resume until the
temperature gets down.
Motor Thermal Protection
The GREEN LED ashes when the motor temperature reaches to the preset
value. The output will not resume until the motor temperature gets down.

14
Note: this protection works only when the temperature monitoring cable on the
ESC is plugged into the temperature monitoring port (marked with “TEMP”) at
the bottom of the matching HOBBYWING motor. It will be void if you don’t plug
the cable into the port or set the “Motor Thermal Protection” to “Disabled”.
Motor Rotation
Pull the throttle trigger with the motor shaft facing you, the motor spins counter
clockwise. When this item is set to CCW; the motor spins clockwise. When it
is set to CW. The (A/B/C) wiring order of motors from different manufacturers
may vary, so do the direction of the motor rotations. You can adjust the “Motor
Rotation” or swap any two (ESC-to-motor) wires if the motor runs in reverse.
BEC Voltage
1. 6.0V: It’s applicable to ordinary servos. Do not use this option with high
voltage servos; otherwise your servos may not function normally due to
insufcient voltage.
2. 7.4V: It’s applicable to high voltage servos. Do not use this option with
ordinary servos; otherwise your servos may be burnt due to high voltage.
Brake Force
The ESC provides proportional braking function; the braking effect is decided
by the position of the throttle trigger. It sets the percentage of available braking
power when full brake is applied. Large amount will shorten the braking time
but it may damage your pinion and spur. Please select the most suitable brake
amount as per your car condition and your preference.
CAUTION: 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. 12.5%: This is the lowest setting and should only be used when driving with
slow motors and on loose (low traction) surfaces.
2. 25%
3. 37.5%
4. 50%: It is not recommended to go below this setting on asphalt surfaces as
the stopping power may not be enough to safely slow your vehicle.
5. 62.5%
6. 75%: This is the default setting we feel will provide you the best starting
point for many different levels of traction on various surfaces. 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 cause serious injury.
7. 87.5%
8. 100%: This setting is only recommended if you are running a slotted type
motor, running this with a slotless style motor combined with a 4wd vehicle
will likely cause front ips thus a loss of control of your vehicle.

15
Reverse Force
Different reverse amount will bring different reversing speed. For the safety of
your vehicle, we recommend using a low amount.
Start Mode/Punch
You can choose the punch from level 1 (very soft) to level 5 (very aggressive)
as per the track, tires, grip, conditions. This feature is very useful for
preventing tires from wheel-spinning during the warm-up process. In addition,
“level 4” and “level 5” have strict requirement on battery’s discharge
capability. It may affect the starting-up if the battery discharges poorly and
cannot provide large current in a short time. If the car stutters or suddenly
loses power in the starting-up process, indicates that the battery’s discharge
capability is poor, you might need to reduce the punch or increase the FDR
(Final Drive Ratio).
1. Level 1 (60%)
2. Level 2 (70%): This setting will provide the smoothest throttle feel and
least wheel spin.
3. Level 3 (80%)
4. Level 4 (90%): This is the highest setting that should be used with high
performance NiMH batteries such as those included with your vehicle.
5. Level 5 (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.
Drag Brake Force
Drag brake is the braking power produced when releasing from full speed to
neutral zone. This is to simulate the slight braking effect of a neutral brushed
motor while coasting.
1. 0%: This setting allows the vehicle to continue to roll after letting off
throttle without applying automatic-brake
2. 2%: 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 easier.
3. 4%: Add more until you nd the right balance of assistance with slowing
down while still being able to maintain good corner speed without
upsetting the vehicle.
4. 6%
5. 8%
6. 10%
7. 12%

Adjusting and Tuning Your Vehicle
The Select Four 10TR has been engineered with some available tuning
options listed here for reference. The default conguration 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 ideal to have the drive shafts above level but still allow the shocks to
extend when you lift the vehicle while the vehicle is sitting on a at surface
with the body installed. Use the threaded adjustment collars to achieve the
desired ride height.
• Lowering the collar will raise the ride height of the vehicle and if done
excessively may decrease stability.
• Raising the collar will lower the ride height and may cause the chassis to
drag on the ground.
Upper Shock Position
There are multiple shock installation locations for the top mounting location
of the shock towers. The default positions have been chosen as a good
starting point. Moving the shock mounting location inward will result in a
slightly less responsive feel on the front or rear of the vehicle but it will be a
little more stable. Moving the shock mounting location outward will make the
truck more responsive but less stable in some conditions.
Lower Shock Position
There are multiple shock installation locations for the lower mounting
location of the shocks in the suspension arm. The default location is ideal for
the included shock length. However you can play a little.
• Moving the shocks to the inside location will result in a slightly more
responsive feel on the front or rear of the vehicle but become a little less
stable. This change will also increase the vehicle’s articulation and you
will notice more 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 foam blocks used to position the battery.
Centered is the default location.
• Moving the battery forward will generally give the vehicle more steering
while exiting a turn, but less while entering a turn.
• Moving the battery backwards will generally give the vehicle a little more
traction but less steering while on power.
• Ensure the foam blocks are in place to keep the battery pack from

changing position in the battery tray.
• It may be necessary to reset the ride height after changing to a heavier/
lighter battery or making a setup change.
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 briey
inspect your product for damage every few uses. Typically, a good time to
do this is when changing the battery in your vehicle 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.
ESC and Servo
The ESC and servo included in your vehicle are rated for all weather use. It
is recommended that you avoid submersion of the vehicle however running
in puddles, rain and snow should not be damaging. If you will be running in
a lot of water it is recommended to un-plug the fan from the ESC to prevent
the fan from being over-loaded from the water. Be sure to re-connect the fan
immediately after use and drying the terminals. Always remove excess water/
snow from your vehicle after running to help prevent corrosion. Using an air
compressor is effective but please use eye protection.
Transmitter
Although the receiver included with your radio system is rated for all weather
use, the transmitter is not. The transmitter should not be used in the rain or
other wet environment to avoid damage to the sensitive electronics.
• Clean dirt and debris off of your transmitter regularly to avoid the
consequences of these getting into the sensitive electronics where they
can cause short circuits and/or restrict motion of the internal steering
and throttle mechanisms.
• Ensure the antenna is kept in proper working order. The transmitter is not
safe to use with a broken or missing antenna.

Receiver
Although the receiver included with your radio system is rated for all weather
use, it is recommended that you avoid submersion of the receiver, however
running in puddles, rain, and snow is okay.
CAUTION: ALTHOUGH THE ELECTRONICS ARE PROTECTED FROM THE WEATHER,
THE CONNECTIONS ARE NOT. ELECTRICAL CONNECTIONS WILL CORRODE WHEN
EXPOSED TO MOISTURE WHEN IN USE AND IF LEFT IN A WET CONDITION. IT IS
CRITICAL THAT YOU UNPLUG AND DRY ALL EXPOSED ELECTRICAL CONNECTIONS
AFTER EACH USE IN WET CONDITIONS TO AVOID DAMAGE TO YOUR EQUIPMENT.
• To achieve full operating range with your radio system, it is critical that
the receiver antenna be installed properly and undamaged.
• Inspect any exposed antenna for cuts or abrasions.
• Ensure there are no kinks in the antenna or antenna tube.
• Never fold the end of the antenna over the tube, this will reduce the
range and damage the antenna.
• Ensure the antenna is not being pinched by the set screw that holds the
antenna tube in place.
Gears
Periodically remove the gear cover to clearly inspect the gears and ensure
there is no debris in the gear compartment.
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.
Checking the gear mesh and setting proper backlash.
1. Remove the spur gear cover.
2. Check how much movement is allowed (backlash) of the spur gear
before the pinion gear moves (this is mostly feel, not visual). Check this
movement in multiple places by rotating the spur gear approximately 1/6
rotation and rechecking.
3. 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 correct, it
will be when you are done after following these procedures.
