WIRING INSTRUCTIONS
1) CONNECT ESC TO RECEIVER
Plug the ESC into the throttle (TH) channel of the receiver.
Channel 1: Servo
Channel 2: ESC
“REMEMBER: 1 to Turn, 2 to Burn”
2) CONNECT ESC TO BATTERY
Visually verify that the connector on the battery pack and the
ESC wiring match.
DO NOT CONNECT BATTERY INCORRECTLY TO ESC,
VERIFY THAT THE BATTERY POSITIVE WIRE WILL
CONNECT TO THE ESC POSITIVE WIRE
BEFORE CONNECTING!
3) CONNECT ESC TO MOTOR
First, determine the type of motor you are using.
SENSORED motors require the sensor harness,
SENSORLESS motors do not. Refer to Figures 4, 5 and 6
for wiring brushless and brushed motors.
CAUTION: A power capacitor is supplied with the RSX PRO
and MUST BE MOUNTED on the ESC for proper operation
(Figs. 2 & 3). Failure to use the power capacitor can cause
irreparable damage to the ESC.

Plan Speed Control Placement
1) Choose a location for the ESC that is protected from
debris and moving parts. Plan ahead with wire routing and
try to keep the motor leads about the same length. Motor
leads should be short, but not tight. Leave some slack in the
wiring to account for chassis flex and vibrations while driving.
2) Mock up your wire lengths for your planned ESC
placement. It is recommended to solder the power cap and
all leads to the ESC before mounting to the chassis.
3) Choose a wiring method for the motor and battery leads.
Direct wiring uses no plugs and provides the best
connection between the motor and the ESC. You can use
Tekin 4.0mm Hi-Power bullet connectors (TT3054) for easy
motor removal. Battery connector choice is up to you, use
the female plug on the battery and the male on the ESC and
double check the polarity.
4) To mount the ESC, clean the bottom with rubbing alcohol.
NEVER use any chemicals such as motor spray or acetone
as they will damage the plastic. Use the provided double
sided tape or a 3M adhesive tape.
5) Secure the ON/OFF switch in a safe, accessible place
away from moving parts and debris.
Tips & Tricks
Placing the ESC in a vise (gently) provides
a stable work area to do a quality job ( Fig-
ure 3). Solder without the fan shroud/fan in
place to avoid damaging them. The order for
proper soldering is:
Tin Posts
Tin Wires
Heat Posts
Heat Wires
Heat both and connect
Hint: If the wire is too hot to hold 2” away from the solder
joint, the iron has been on for too long— stop, let everything
cool and try again. Excessive heat can damage the ESC.
Brushless wiring instructions refer to Fig. 4
Brushed, refer to Figs. 5 & 6.

WARNING: Exceeding product specifications or using
equipment outside of the specification ranges above
automatically voids the 180-day manufacturer warranty. Any
damage caused from misuse or use of equipment outside of
the specifications will be subject to servicing and or
replacement fees to be determined by the Tekin Service
Department. For further warranty information, please refer to
Section 22 or visit us on the web at www.teamtekin.com.
NOTE: Before Radio Calibrating, ensure the ESC is
hooked up to the receiver in Channel 2 (CH2), a charged
battery is properly connected, and the transmitter is turned on
and bound to your receiver.
Refer to Section 10 below.
1) On your transmitter, set all trim adjustments to the middle,
throttle/brake EPAs and Dual Rate set to 100.
2) Press and hold MODE for 3-5 seconds or until the ESC
gives a 4 chime confirmation. It is now in calibration mode
and will start by looking for the neutral signal first, while blink-
ing the center (#4) LED with a simultaneous “beep” with each
blink.
3) Once neutral is found, the 4 chime confirmation will sound
again and the right (#7) LED will begin to blink, indicating the
ESC is looking for a full throttle signal. Pull and hold full throt-
tle until you hear the confirmation chime.
4) The ESC will then switch to the left (#1) LED and look for a
full brake/reverse signal. Push and hold full brake until you
hear the confirmation chime. After the confirmation, let go of
the trigger and the ESC will arm, go to neutral and actively
show the onboard temperature (Section 11).
5) If the ESC does not show the temperature monitor ( LED 4
and & cycling back and forth) check Section 8 to see if any
Error Codes are present.

After properly installing your ESC, follow these steps for a quick setup:
1) With the ESC installed and properly wired, (Figs. 4, 5 & 6) connect
the battery.
2) Turn the transmitter on FIRST, then the ESC.
3) Take note any codes that may be present. Refer to Section 18 on
reverse side for codes.
4) Set transmitter throttle trims to 0 and throttle EPAs to 100. You can
access these features in the system menu on the transmitter.
5) Perform a Radio Calibration, refer to Sections 9 & 10.
6) Factory default voltage cutoff is set for a 2S LiPo battery @ 6.4V.
Double check the battery you are using and adjust Voltage Cutoff if
needed.
7) Updating Firmware via HotWire:
Read through this manual and familiarize yourself with the terms, error
codes and general workings of the ESC. Keep this manual for future
reference.
1) The RSX PRO is intended only for 1/10th scale and smaller
vehicles that weigh under 4lbs ready to run.
2) Make sure the motor/battery are within Tekin specs.
3) Check battery polarity! NO Reverse Polarity Protection.
4) Check labeling of solder posts before soldering.
5) Locate the power capacitor and note that it MUST be installed or
warranty will be void. Section 3.
6) Use in or around water can damage the ESC and void the warranty.
Congratulations and thank you for purchasing the RSX
PRO Brushless/Brushed Sensored Electronic Speed
Control (ESC). The RSX comes from years of brushless
R&D and supplies racers with the ultimate package for
modified racing. The small footprint and optional fan shroud
make the RSX PRO versatile and able to cover a wide
range of vehicles and applications.
MOUNTING FAN SHROUD:
(Fig. 1)
Secure the included
25x7mm fan to the shroud
using (4) 6/32 x 3/8 button
head screws (sticker side
down). Route fan wire as
shown. The shroud is
mounted to the RSX using
(4) #1-72 x 1/2 screws and
3mm aluminum spacers.
We offer replacement fans
(TT3833 25mm Fan Pack)
and plastic / shroud kits
(TT3850).

IMPORTANT LED CODES
ALL LEDS FLASHING
No signal from receiver. Check that receiver
bind light is on and ESC is plugged into CH2.
LEDS 1, 2 , 6 & 7
Wrong motor type, or internal short in ESC or
motor detected. Check motor wire solder
joints.
LEDS 1, 2 & 3
LOW neutral signal. Adjust radio trims to
center and perform radio calibration.
LEDS 5, 6 & 7
HIGH neutral signal. Adjust radio trims to
center and perform radio calibration.
LEDS 1, 3 & 5
LOW VOLTAGE CUTOFF. Battery voltage is
below programmed voltage cutoff. Charge
battery.
LEDS 3 & 5
Spec Mode activated. Sensored-Only, no
Timing or Boost. ROAR Legal.
LEDS 3, 4 & 5
Big Event Spec Lockout mode activated. Can
only be undone via HotWire™. ROAR Legal.
LEDS 6, 5, 4 & 3
Fan Reverse Polarity. Check fan plug polarity.
Refer to this section should your ESC show you any LED
sequence out of the ordinary. You can also go to
www.teamtekin.com/esc_codes.html to see these codes in
action. Each code will FLASH rapidly:
The On-Board Temperature Monitor works to provide you
with important feedback on ESC temperature, helping you
to adjust gearing and avoid long term heat damage. To
use:
1) The ESC must be calibrated to your transmitter and
must be in neutral.
2) The middle LED will be on steady then blink out every 2
seconds. *Blinky mode will show LEDs 3 & 5 blinking
rapidly in neutral and Locked Spec Mode will show LEDs 3,
4 & 5 blinking rapidly.*
3) At the moment that the center LED blinks out, one or
more of the other LEDs will light up.
4) LED Temperature readings:
Should your ESC show all 7 LEDs, stop driving and let it
cool. The ESC will go into Thermal Shutdown if it is not
allowed to cool down. You may need to lower your gearing,
lower your Boost settings, change to a higher turn motor or
repair any binding in the drivetrain. Continuous use at high
temperatures and multiple “thermals” can damage the
ESC.
