LED1: DRAG BRAKE provides immediate braking
action in the neutral zone. This gently slows the car
down when you let off the trigger. Higher values
increase the degree of drag braking.
LED2 (IN BRUSHLESS MODE): REV/BRAKE
STRENGTH
adjusts your maximum brake strength
and reverse speed when in brushless mode. Higher
values increase brake strength and increase reverse speed.
LED2 (IN BRUSHED MODE): PUSH CONTROL or ANTI-DRAG
overcomes the natural drag of a brushed motor when throttle
returns to neutral. This setting eliminates the need to trim the
throttle forward to create a coasting (pushing) effect. Low values
give you a short duration push, higher values a longer duration
push.
LED3: CURRENT LIMITER adjusts the throttle
response during acceleration, gentle to abrupt. Low
values allow low amounts of current to pass to the
motor, higher values allow higher amounts of current. The high-
est value (13) turns off current limit.
LED4: NEUTRAL WIDTH adjusts your dead band
around the neutral point. A low neutral width value
provides more sensitive trigger response around
neutral. A higher value allows you to move the trigger slightly
before throttle or brake is engaged.

The On-Board Temperature Monitor works to provide you with
important feedback on speed control temperature, helping you to
adjust gearing and avoid long term heat damage. To use;
1) The speed control must be calibrated to your radio and the
radio must be in the neutral position.
2) The middle LED will be on steady then blink out every 2
seconds.
3) At the moment that the center LED blinks out, one or more
of the other LEDs will light up.
4) LEDs 1-3 lit is typical of light loads or a stock motor. LEDs
1-6 lit indicates heavy loads and is typical when running
mod motors. LEDs 1-7 lit indicates high internal tempera-
tures approaching thermal shutdown. Discontinue use until
the speed control returns to normal operating temperature.
SERVO WORKS, THROTTLE DEAD
If LEDs 1,3 and 5 are flickering, it indicates that Voltage Cutoff
may be set above battery pack voltage. Check that cutoff is cor-
rectly set and that battery is fully charged. Motor or connections to
motor are bad. Speed control not plugged into throttle channel on
receiver, or receiver plug connection is bad. May be in Pit Tune
mode.
STUTTERING UNDER HEAVY ACCELERATION
Damaged or disconnected power capacitor.
Receiver bad or getting
magnetic field interference. Try adding an electrolytic cap on the
power supply (BATT socket) of receiver. Move power wires away
from receiver. Remove any zip ties securing wires and check for
kinked, broken, or damaged motor wires. Twist motor wires around
each other to help suppress noise.
WILL NOT CALIBRATE
Neutral on radio is set outside of the speed controls expected range,
adjust throttle trim and/or trigger “NORMAL/REVERSE” setting.
BRAKES DO NOT WORK AT ALL
Speed control or radio transmitter improperly adjusted. Adjust
EPAs on transmitter all the way out and recalibrate speed control to
radio.
MOTOR RUNS BACKWARDS
First check that your radio trigger setting is set to NORMAL, not
REVERSE, then perform a radio calibration.
BRAKE STRENGTH: Reducing your brake strength helps con-
trol excess skidding during heavy braking and on loose surfaces.
DRAG BRAKE: Increased drag brake settings help by allowing
you to concentrate less on braking, more on driving a good line,
and can also be very helpful with free-spinning slotless motors.
NEUTRAL WIDTH: A tight neutral width can interfere with
correct operation of Drag Brake and Push Control if your radio
trigger does not return precisely to the same neutral position.

For RS/RS Pro Brushless Connection, Refer to Figure 6.
1) Connect the battery pack: BAT (+) to the speed control
BAT (+) then BAT (-) to the speed control BAT (-).
2) IMPORTANT: Before connecting the motor, determine if
the motor is sensored or sensorless and that you have the
correct motor type selected on the speed control.
3) Select Motor Type: Press and release the MODE button 6
times to get to the MOTOR TYPE selection in the user
settings. Press and release the INC button once to view the
current motor type selected (brushless types are indicated
by LEDs 1-3 lit). If necessary, continue to press and re-
lease the INC button to scroll through the motor types until
brushless motor type is selected.
4) Wiring: Connect A, B and C wires from the motor to the
A, B and C posts on the Speed Control, verify this is correct
for proper function. Determine whether you would prefer to
use connectors from speed control to motor and from speed
control to battery. Refer to the instructions in the Soldering
section of this manual for more information and refer to
Figure 1.
5) Power off the speed control and connect the motor wires,
matching colors appropriately.
6) Power on the speed control, listen for the arming chime.
Congratulations, you are ready to drive!
For RS/RS Pro Brushed Connection, Refer To Figs 7 or 8.
1) Connect the battery pack: BAT (+) to the speed control
BAT (+) then BAT (-) to the speed control BAT (-).
2) IMPORTANT: Before connecting the motor, first plug
the speed control into the receiver, connect a charged
battery, then power on your transmitter. Turn on the
speed control and perform a radio calibrate.
3) Select Motor Type: Press and release the MODE button 6
times to get to the MOTOR TYPE selection in the user
settings. Press and release the INC button once to view
the current motor type selected (brushed types are indi-
cated by LEDs 1-4, 1-5, or 1-6 lit—See Adjustment
Modes table for motor type details).
4) Forward Only Wiring (use only Motor Type 4): Refer to
Fig. 7 and the instructions in the Soldering section of this
manual. Connect all 3 speed control motor outputs to-
gether, then connect them to the NEG (-) terminal of the
motor. Connect another wire from the motor’s POS (+)
terminal to the BAT (+) terminal on the speed control.
5) Forward/Reverse Wiring (Motor Types 5&6): Refer to
Fig. 8, connect motor NEG (-) terminal to speed control
(C) post, then connect motor POS (+) terminal to speed
control (A) post. NOTE: Speed control (B) is not used.

OPERATING TIPS
The HotWire PC Interface (TT1450) unlocks the full potential
of your Tekin Speed Control, much more than just a pretty in-
terface to your user–adjustable settings.When you connect the
HotWire to your speed control you can download and install the
latest software revisions as improvements and features are
added to the speed control design. Further, because Tekin con-
tinually seeks to push performance levels, we occasionally re-
leases Beta Version Software. With the HotWire you can, if
you so choose, elect to join the team and become part of our
Product Research and Development at Team Tekin.
The HotWire also allows you to adjust several hidden features
not accessible through the on-board programming, such as user-
defined Custom Throttle Profiles, Custom Voltage Cutoffs and
adjustable timing.Another feature is the ability to save and re-
load settings. If you want to recall the settings that helped put
you in the A-Main last time, you can save your settings, then
later instantly tweak your speed control to revert to that particu-
lar track and specific driving conditions. If you feel like level-
ing the playing field, you can share your custom settings with a
friend.
Even better, downloadable speed control configurations from
our top-level drivers give you access to the exact speed control
settings that they have used in specific setups and for particular
races! Check it out at www.teamtekin.com/HotWire

The RS series speed control is capable of running all brushless mo-
tors in sensorless mode. In sensored mode the default used is
Tekins D2 technology, this “Dual Drive” allows the speed control
to start out in sensored mode then switch to sensorless mode while
at higher rpms. Dual Drive mode uses mechanical/motor timing at
start up then uses software driven timing after the start up routine
has phased into sensorless drive. There is also a sensored only
mode, this mode only uses the mechanical/motor adjusted timing
during its entire run.
With Tekins RS series speed control you can quickly verify your
speed control and motor are communicating properly simply by
observing the RS LEDs to the right (5, 6 and 7). If the RS speed
control is reading the motors sensors, LEDs 5, 6 and 7 will dimly
light up in a sequence corresponding to the rotation of the shaft.
This indicates that all sensors with in the motor are functioning
correctly and the system is ready to roll. Should one sensor go bad
during the course of a run the RS switches into sensorless mode,
enabling you to finish out the race!
If you are not seeing LEDs 5, 6 and 7 dimly light up in a se-
quence: -Check that your sensor wire harness is secure.
-Insure that there are no broken pins or a damaged wire harness.
-Cross check with another sensored motor. This will tell you
whether or not you have a damaged hall effect sensor with in the
motor.
