INTRODUCTION
that each of the wires can be removed from the black plastic plug housing. (Figure
1, step 1)
Thank you for purchasing Tekin’s innovative new series of advanced speed
control. The G-10 continues the winning performance tradition of the 411-G2, G9, and G-12c III, but adds new multiple-setup tuning capabilities. Simple two
button operation allows quick and accurate adjustment of all critical operating
parameters. This results in better operation over a wider variety of car and track
use conditions. Our new double-shunted, surface-mounted GoldFET III-b power
MosFET transistors offer the highest performance available, and CoolSwitch IIPro circuitry with Copper-Clad mounting delivers extreme performance with
reduced heat. This allows higher sustained peak power delivery throughout the
whole run. The new rear-mounted transistors also lower the center-of-gravity, for
better cornering. The slim case fits easily into any make chassis, and the wiring
layout is improved. Other features include Tekin’s Throttle Priority Circuitry (TPC)
which guarantees full bottom-end power under the most severe loads, versatile
QuickTune PRO setup for optimum performance at all times, reverse voltage
protection for total reliability, built-in 32 amp high power Schottky diodes, reduced
weight, native machine-code software for higher processing speeds, and 16 bit
wide math computations for the most accurate, low distortion link between the
driving trigger and motor output.
2) After removing the wires from the receiver plug, use a hobby knife or jeweler’s screwdriver to lift the metal tabs on each of the wires back up. (Figure 1, step

incorrectly may damage
the speed control or radio
receiver and void the warranty.
Specifications are subject to change without notice.
STEP 1 - CONNECTOR SELECTION
STEP 2 - MOUNTING
This speed control features the Tekin Universal Radio Connector System. This
allows you to use it with Tekin, Airtronics/Sanwa, Futaba J, JR, KO Propo, and
other receivers.
A) Mount the speed control using the double-sided tape provided or “Shoe Goo”.
It is best to cut the tape to fit the plastic area on the back of the speed control. Clean
the chassis and speed control first with motor spray or solvent to provide maximum
adhesion. The new generation MosFET transistors are mounted on the back of the
unit in a spaced-apart manner which provides increased surface cooling area. All
normal mounting locations are acceptable. There are no special air-flow
requirements, but it is best to avoid closing off the side vent areas. Most
installations will be with the speed control on the chassis, on the same side as the
motor brushes. Be sure to keep the power wires away from the receiver and to
allow access to the Setup Buttons.
B) Mount the on/off switch with servo tape or the screws supplied. DO NOT USE
SUPER GLUE.
The standard connector on this unit is the Tekin / Futaba J. If your receiver is a
Tekin or a Futaba, then the standard plug will fit without modification.
When using this speed control with Airtronics, Airtronics Z, JR, KO Propo,
or other receivers, follow the steps below:
**NOTE: Kyosho Receivers use the “JR” plug housing**
1)
First, disconnect the battery from the speed control. Using a small
hobby knife or jeweler’s screwdriver, press in the three metal tabs only far enough

FUSE REPAIR
This speed control uses an exclusive zero-loss solder-drop fuse link for higher
efficiency, for improved performance, and the coolest operation. The patented
circuit also delivers longer run time than any other Schottky diode circuit. This
special fuse also eliminates damaged diodes due to an overload or accidental
reverse voltage hookup. Instead, you need only replace the solder on the fuse
link.
To repair the fuse, use a small-tipped soldering iron, and always wipe the tip off
before starting. Touch the tip of the iron to the metal pins on the fuse, then apply
a small amount of solder as close to the pins as possible. Hold the iron upright so
the solder can flow down the iron onto the pins.
If you apply too much solder, hold the speed control upside down and touch the
iron to the solder allowing it to melt and flow down onto the iron tip. Wipe the
solder off the tip and start over.
This speed control has its own exclusive circuit with the
Schottky diode built in for maximum performance. There
is no need to use an external Schottky diode on the
motor. If you do use a second diode on the motor, the
speed control will not be damaged but such a second
diode will slow the car down slightly.
If you follow these simple instructions, your speed
control will have a long life offering great performance
and trouble-free operation.

STEP 5 - QUICKTUNE RADIO CALIBRATION
Once you have completed the wiring and hooking up your speed control, the
speed controller must be calibrated to your transmitter. Tekin's QuickTUNE
electronic setup feature allows this to be done quickly, easily, and accurately. For
optimum performance, first adjust the transmitter according to the chart below,
then proceed with the following steps.
1) Turn on the transmitter, then the speed control, and leave the transmitter in
the neutral position.
2) Press and hold EITHER BUTTON (but not both at once) for about 5 seconds
until the left hand red light starts blinking rapidly. Then pull full throttle on the
transmitter, and then push forward to full brake. Release the trigger. (You have
about 5 seconds to do this). After the light stops blinking, the calibration is
complete and you are ready to drive.
3) To adjust the maximum brakes, use the brake trim or EPA / ATL / ATV low
adjustment on the transmitter. You may need to do this to reduce the braking
somewhat. Whenever you re-set the speed control, be sure to put the transmitter
brake trim or EPA / ATL / ATV back to maximum first.
Note: If you do not apply brakes during the calibration procedure, the brakes will
be disabled.

STEP 4 - MOTOR & BATTERY HOOK-UP
Please exercise extreme care when installing your speed control, as damage can
easily occur. Check with your dealer if you think you might need help.
NOTE: The speed control supplies power to the receiver and servo. No additional
power supply should be used for the receiver. Make sure the battery plug of the
receiver is disconnected. Avoid turning on the radio when the batteries are charging.
A) Plug the wire harness from the speed control into the throttle channel of the
receiver. The speed control supplies a regulated 5.8 Volts to the receiver and servo
when running on 4 to 8 cells. The regulator puts out enough current for up to 4 micro
servos or 1 high power servo.

STEP 3 - SOLDERING
The wire terminal posts featured on this speed control (G-10 only) allow you to
run wires of just the right length for any installation without worrying about them
becoming too short. The posts are 10GA gold-plated copper for the lowest
resistance. If you need to ever change a wire on the speed control, follow the
steps below. You will need a very hot soldering iron (750ºF to 850ºF), and ordinary
60/40 electronic grade solder. IMPORTANT: Use extreme care and observe
proper safety precautions when soldering. Always wear eye protection. Be sure
that both wires are disconnected from the battery before soldering to the posts.
REMOVING A WIRE FROM A POST:
1) Have the iron very hot and the speed control secured in place. Clean the tip
of the iron and apply a small amount of solder. While the tip is still smoking from
the flux in the solder, touch the tip of the iron to the top of the post.
2) As the solder on the post melts, pull on the wire you wish to remove. The wire
will pull off easily.
3) If there is excess solder remaining on the post, you may remove it by heating
the post until the solder just starts to melt, then quickly tapping the speed control
firmly against the workbench to knock off the excess solder.
ATTACHING A WIRE TO A POST:
Note: Disconnect wires from battery before soldering. Refer to markings on the
speed control for proper wire locations.
1) Strip back the insulation of the wire by about 3/32 to 1/8" (2 to 3mm) and "pretin" the wire by heating the end and applying solder until it is thoroughly covered.
You may shake of any excess while it is still hot. Be very careful to not splash
yourself with hot solder.
2) If there is no solder on the post , touch the tip of the iron to the top of the post
and apply a small amount of solder to the post. Wipe the tip clean and apply a
small amount of fresh solder to it.
3) Secure the speed control in place on the workbench. Hold the wire so the
tinned end is in contact with the flat side of the post. Now touch the iron tip to the
wire pressing toward the post. Wait about 2 seconds for the solder to flow, then
remove the iron while still holding the wire. You may let go after a second or two
when the solder sets.
Note: It should only take a few seconds to solder a wire to a post. If you do not
complete the solder joint in approximately 3 seconds, remove the iron, clean and
tin the tip, and start over. The posts are attached to the circuit board with hightemperature silver solder for reliability, but excessive heat should be avoided.
STEP 6 - PROGRAM ADJUSTMENTS
HAIRPIN TRIGGER:
If you wish to have a very short trigger range, then only squeeze the throttle
trigger partially during the set-up procedure. Throttle response will not be quite as
smooth, but you can pull full throttle very quickly.
Once Calibrated, the lights on the speed control will advance as the throttle or
brake are applied. The “0” light is Neutral, and the “MAX” light is full throttle/brake.
There may be some flickering in between lights as the throttle is advanced. This
is normal, and is caused by modulation noise fron the radio.
Initial set-up is now complete. You may proceed to step 7 if you do not wish to
adjust the modes yet.
MODE SET-UP
The G-10 offers unparalleled tuning options. Every performance influencing factor may be adjusted. Advanced exclusive software routines are used so you can
obtain just the right action. Adjusting the modes on the speed control is very sim ple. There are just 2 steps.
1) First, press the MODE button to access the desired setup mode. The left light
will start blinking to indicate that mode selection is under way. Continue pressing
the mode button until the light advances to indicate the mode you wish to adjust.
Do not wait longer than 5 seconds to select the mode, or the speed control will
return to normal operation. Once the mode is selected, move on to step 2 within
5 seconds.
2) Second, press the “INCR” (increment) button to adjust the value. The first
time the INCR button is pressed, the light(s) will indicate the existing setting. Each
time the INCR button is pressed again, the value will advance toward MAX, then
start over again at the low end of the scale. If two lights are on at once, it indicates
a value mid-way between the LEDs. Most modes have 9 or 10 possible settings.
If you wish to set another mode, you may go back and press the MODE button
again. After a 5 second pause, the values you selected will be saved in memory
and the speed control will resume normal operation.

1. The BRAKE MINIMUM setting determines how
strong the brakes begin initially. Higher values make
the brakes come on strong with little trigger
movement, and provide a generally more aggressive
response. This can speed up trigger response by
eliminating unused trigger motion, but very light
braking will be lost. A value of zero provides very
light, fine braking action.
2. The DRAG BRAKE control provides immediate
braking action, even in the neutral or “coast” zone.
This gently slows the car down when you let off the
trigger. This can allow a better cornering approach.
Higher values increase the drag braking. A value of
0 provides maximum coasting in neutral.
3. The NEUTRAL setting controls the deadband in
between throttle and brake where the car just
coasts. It adjusts from 1%-10%. Generally, narrower
settings provide quicker response for tight racing
applications. You may need to re-trim the throttle
occasionally on the transmitter if an excessively
narrow neutral point is used, as most radios fluctuate
a bit. This will also depend on the transmitter battery
level.
4. The THROTTLE curve controls how aggressively
the throttle comes on at the bottom end. Higher
values increase the bottom end response, and
require less trigger travel to reach the same speed.
A value of 0 is a linear response, with a very slow low
speed crawl. You should select a value based on
motor power and gearing that provides smooth fluid
trigger motion when driving. Although shown as a
straight line, the actual curve is slightly rounded. This
feature provides smoother driving by allowing nonlinear response matched to the motor power curve.
-9-
5. On a DC electric motor, torque is proportional to current flow. The current
limiters LIM 1 and LIM 2 regulate how much current can flow to the motor to
control torque and excessive wheelspin. They also provide longer motor life by
reducing burned brushes. The G-10’s exclusive fully digital current limiters
provide precise, perfectly repeatable results every time.
LIMIT 1. This is the current limiter for the first 3 seconds. The 3 second timer
begins the first time you pull full throttle after turning on the speed control. You
may still drive the car and do trim adjustments on the starting line as long as you
only use partial throttle. If you pull throttle, you may turn the speed control off and
then back on to reset the timer. Lim 1 may be adjusted from 10 to 90 amps, plus
bypass (MAX). In the MAX mode, the current limiter is totally disabled and the
speed control can pass the full short-circuit battery current. Use LIM1 to set the
amperage you need off the starting line. This will be a high value for high traction
racing, and a low value for racing with capped tires, etc. The speed control also
contains Tekin’s exclusive Vari-Torque current limiter. This design provides a
small change in the current limit amperage depending on how much throttle is
applied. This means the driver has continuous control of the car’s throttle – even
when the current limiter has kicked in.
6. LIMIT 2. This current limiter takes over when the 3 second timer on LIM 1
expires. Set this limiter to a high value for normal driving, or to a low value to
conserve battery power and motor life, or when driving on slippery tracks. NOTE:
Setting the limiter to a value of 10 may not allow enough power for the motor to
reach full RPM. In this case, increase the current limiter setting.
Pit Tuning: If you are in the pit area and do not have access to your transmitter,
you may still make speed control adjustments by following this procedure: Hold
down either the MODE or the INCR button (but not both) while turning the power
switch on. The settings and controls will be active, but the motor will not run and
the speed control will not respond to receiver signals. If the steering servo
continues to run, you will need either to unplug the servo from the receiver, or
remove the crystal from the receiver. Turn the speed control power off and back
on to resume normal operation.
STEP 7 - RADIO INSTALLATION TEST
If you have any sign of radio glitching (the throttle or steering does not always
seem to respond to the transmitter
correctly), perform this test. Turn the car on
MICRO RECEIVER
with fully charged batteries and hold the
INSTALLATION
rear wheels so the motor is stalled. Apply

servo for any movement or jittering. If the
servo remains still, the installation is fine.

Otherwise you will need to move the

receiver and/or the battery wires to a
different location. Do not run the large
battery wires or strap near the receiver.
A Tekin Micro Receiver is highly recommended. They are exclusively designed to
operate down to 2.2 Volts for strong
acceleration, and are available with chrome
shielding for greater range.

SELF-TEST & TROUBLESHOOTING
The G-10 has a built in SELF-TEST mode that checks all major systems on the
speed control. Before using the self test mode, make sure the rear wheels are
free to spin. To activate the self-test, turn the speed control on, then press and
hold both the MODE and INCR buttons simultaneously for 3 seconds. After 3
seconds the motor will run. The motor should accelerate to full speed, then the
brakes should come on. This should happen 3 times. Most other circuits and
systems inside the speed control are also checked automatically. If everything
tests okay, all the LED light’s will flash simultaneously at the end of the cycle. A
bad motor will cause the test to fail, check #2 below. If the motor is known to be
good, and still only one or a few lights flash at the end of the test, there may be
an internal problem – but this is unlikely.
Activating the self-test mode also resets all the mode selection and other set-up
parameters to factory default values. (SEE CHART ON PAGE 8). The user’s radio
calibration settings will not be changed.
If the receiver does not supply a proper signal to the speed control, the speed
control NEUTRAL LIGHT will blink. In this case, check the radio system.
OTHER PROBLEMS:
1) SERVO AND THROTTLE DEAD:
Dead batteries. Bad connections to speed control. Bad receiver plug connection.
Customer-installed receiver plug is wired wrong. Switch needs replacing. Broken
wires. Bad crystals, radio equipment or blown fuse.
2) SERVO WORKS, THROTTLE DEAD:
Motor or connections to motor are bad. Motor brushes hanging up. Speed
control not adjusted correctly. Receiver plug or connections are bad. TSC not
plugged into throttle channel on receiver.
3) THROTTLE WORKS, SERVO DEAD:
Bad Servo. Servo plug or wiring bad or incorrect.
4) STUTTERING UNDER HEAVY ACCELERATION:
Receiver suffering magnetic field interference: Try mounting receiver on its side
and/or spacing it 3/16 inch up from the chassis. If this does not work, try mounting
it on its other side. Move power wires away from receiver. Also try wrapping the
receiver in aluminum foil if it must be placed close to power wires, or use a Tekin
chrome sheilded receiver.
5) MOTOR CUT OUT, RADIO INTERFERENCE or POOR RANGE:
No capacitors or insufficient capacitors on motor: Try 2 sets of capacitors.
Incorrect control wiring to receiver or servo. Transmitter Batteries Low or radio out
of tune. Three-wire cable from speed control to receiver may also be too long; 6
inches (152mm) is the maximum.
This speed control radiates very low noise and you should have no trouble with
interference. If you do have interference, mount the speed control in the pan, and
mount the receiver and antenna at the top of the shock tower. Also try wrapping
the receiver in metal foil, or use Tekin’s chrome shielded micro receiver.
Try to keep the receiver away from the batteries or power wires. Also try to space
the receiver away from any metal or graphite. Using a double or more thick layer
of servo tape helps. Do not run the antenna along a metal or graphite chassis; it
-11-
should mount straight up from where it exits the receiver. It is always a good idea
to keep the receiver and antenna away from the motor, batteries, and power
wires. Also see Step 7, page 10.
6) AUTOCOUNT NOT WORKING:
Capacitors required on motor. (see step 4, -"Wiring Diagram") Mount
transponder at front of car away from batteries and wires. Move autocount pickup
to a place on the track where throttle is wide open (not accelerating). If these do
not fix the problem, replace with new autocount system.
7) MOTOR WILL NOT SHUT OFF OR RUNS SLOWLY:
Moisture in speed control: Unhook batteries and let the speed control dry.
8) SPEED CONTROL SHUTS DOWN:
Motor or capacitor shorted, or motor stalled. Motor diode shorted. Gears or
transmission are binding. Incorrect current limiter settings. Speed control
overheating: Heatsinks and/or more airflow needed.
9) BRAKES DO NOT WORK AT ALL:
Speed control improperly adjusted: Recalibrate (STEP 6). Also, be sure the
brake adjustment on the transmitter is turned to maximum before calibrating.
