Tekin B1, B1-R Owner's Manual

NOTE: Before Radio Calibrating, ensure speed control is

hooke d up to the recei ver, a charge d battery i s properly co n­nected, and the transmitter is turned on. On your radio, set all
trim adjustments to the middle, throttle/brake EPAs set to max
and ensure that your throttle directio n is set to “normal” .
Calibrat ion is real ly very si mple, you j ust press and hold the
MODE butto n for 3 sec onds to e nter radio calibrate , let the
speed co ntrol “find” yo ur neutral , then let i t “find” your ful l
thrott le and full br ake. If yo u are unsure how to pe rform this
procedure, follow the detailed steps outlined below.

Congratul ations on your purchase of the B1/B1-R, Tekin’s

OWNER’S MANUAL

INTRODU CTION

The fo llowing stat ements nee d to be under stood befo re using
the B1/B1-R:

1. Turn on the transmitter first to avoid uncontrollable noise
to speed control.

2. Dis connect batt ery from s peed control when not in use .

3. Do no t hook-up the battery backw ards! No re verse volt­age prot ection.

4. Do no t operate s peed contro l in or around wat er.

5. Insul ate expose d wires wit h heat shr ink tubing to prevent
short circuits.

6. The B1/B1R is intended f or Mini vehic les only.

SOLDERING

IMPORT ANT: Use extreme care and observe proper safety

precaut ions when so ldering. Al ways wear e ye protect ion. Be
sure t hat both wires are disconnec ted from the battery befo re
soldering on the posts.

Never keep a hot soldering iron on the speed control solder
posts fo r more than 3 seconds—the sol der post may beco me
de-sol dered from the spee d control and beco me damaged.

HINT: It should only take a few seconds to solder the wire to

the post. If you do not complete the solder joint in approxi­mately 3 seconds, remove the iron, clean and tin the tip, then
repeat the procedure below. Applying a small amo unt of sol der
paste f lux can oft en help so lder flow on a st ubborn sur face.

SOLDERING CONT...

ATTACHING WIRES TO THE SPEED CONTROL:

1) Red Wire s are usual ly used to connect the speed co ntrol
to the positive battery terminal and the positive motor
terminal . Black wire is typic ally used for t he batter y
negative t erminal , and blue is used for the negat ive motor
connection. Inspect the sticker on the speed control or
refer to the diagrams to determine which color wire to
attach to each post.

2) Strip back the insulation of the wire by about 3/32” to
1/8” and “pr e-tin” t he wire by heat ing the end and a pply­ing sol der until it i s thoroughly c overed. You may s hake
of any excess solder while it is still hot. Be very careful
not to splash yourself with hot solder.

3) If there is no solder on the post, place the tip of the iron in
the notc h on top of t he post and apply a small amount of
solder to the post. When the solder has flowed, remove
the sol dering iro n, wipe the t ip clean and apply a smal l
amount o f fresh sol der to it.

4) Hold t he wire so the tinned e nd is in co ntact with the
notch of the post . Now touch the iron ti p to the wir e and
the post. Wait about 2 seconds for the solder to flow, and
then remove the iron while still holding the wire. You
may let go of the wire after a s econd or two when the
solder sets.

Fo r B1 C onne ctio n Diag ram, Ref er to Fig ure 2 ,
For B1R Connection Diagram, Use Figure 3.

1) Placement : Choose a l ocation for the spee d control that is
protect ed from de bris. HINT: To pre vent radio i nterfer­ence place the speed control as far away from the radio
receiver as possible and keep the power wires as short as
possibl e. If poss ible plan o n routing power and moto r
wires away from the radio receiver and radio wires.

2) Mounti ng: For best results cle an the bot tom of the s peed
control and chassis . Using the doubled-sided t ape,
(incl uded) mount the speed contr ol to chassis .

3) Using a sm all piece of double-side d tape, mount the ON/
OFF switch in a convenient place.

4) Determ ine how you would pr efer to co nnect the motor
and batte ry pack to the spee d control. U sing connec tor
pairs i s prefer able for mos t applic ations as i t allows yo u
to e asily switch bat tery pac ks and change motors.
Whether using co nnectors or di rect sol dering, co nsider
where yo ur batter y pack sits and how much wir e will be
needed to attach to the speed control.

Startup Se quence

When the po wer switc h is turned ON t he speed contr ol begins
looking f or the neut ral signal. If a neutral si gnal is found t he
Arming Seque nce (fl ashes LEDs /chime) will occur fol lowed by
LED3 on s teady

. NOTE: If Arming Sequence does not occ ur

see Troubl e Shooti ng section of this manual be fore pr oceeding.

One Touch Radi o Calibratio n

1) Turn on transmitter.

2) Turn on speed control.

3) Press and ho ld the M ODE button o n the spee d control for
3 seconds. All LEDs will blink red 3 times with 3 chimes.
The spee d control will make a pulsi ng chime as i t looks
for a neut ral signal— you do not need to do anything ye t.

4) When NEUTR AL positio n is found and r ecor ded, LED3
will fl ash and a confi rmation chi me will so und .

5) The puls ing chime wil l begin agai n and LED6 will flas h;
pull tr ansmitter t rigger to the full t hrottle posi tion and
hold unti l the confi rmation chi me sounds.

6) The puls ing chime wil l begin agai n and LED1 will flas h;
push trans mitter tr igger to the f ull brake pos ition and hold
until t he confirmat ion chime sounds .

7) Release trigger to return to neutral position. LEDs will
flash and t he arming se quence chi me will sound.

8) LED3 is now on steady. C alibrati on is co mplete and you
are ready t o drive!

NOTE: If any pro blems occu r, repeat r adio calibrat ion.
HINT: Once calibrated, the LEDs on the speed control will

advance as the t hrottle or brake is appl ied.
Hairpin Trigger Response: If you wish to have a very sho rt
trigger range, the n only sque eze the thro ttle/br ake trigger
partial ly during the radio calibr ation proce dure. Throttl e/Brake
response will not be quite as smooth, but yo u can pull full
throttle very quickly.

QuickTune :

1) Press the MODE button to access the desired setup mode.
The LED starts blinking to indicate that mode selection is
under way. Each time t he MODE butto n is pressed and
released, the LED advances. For example, to get to the
Voltage Cutoff adjus tment, si mply press and releas e the
MODE button 6 times. NOTE: Do not wait longer than
5 seconds to adjust the selected MODE or the speed con­trol wil l return to normal ope ration.

2) Press and release the INCR button to adjust the value.
The first time INCR button is pressed, the LED(s) will
display the existing setting. Each time the INCR button is
pressed the value will advance, then after maximum, start
over again at the low end of the scale. If two LEDs are
on at once, it indicates a value mid-way between the
LEDs.

QuickTune Exam ple: Let ’s say you want t o use a 2 cell LiPo
battery. To change the Voltage Cutoff from the default setting
(1 = None) to setting 2 (2 = 6.0 Volt Cutoff), first follow step 1
above by pr essing and r eleasi ng the MODE but ton 6 tim es.
Now press and release the INC button, the LED should show
the curr ent setti ng of 1. Press and release the INC button agai n
and the LED will move to position 2, indicating that Voltage
Cutoff is now set to 6.0 Volts. Wait 5 seconds and the ESC
returns to normal operation.
HINT: If you wis h to set a nother Pro gram Feat ure, press the
MODE butto n again. After 5 seco nds pause, the values yo u
selected will be saved in memory and the speed control will
resume normal oper ation.

PIT TU NING : If you are in the pit area and cannot use your
transmi tter you may us e pit t uning mode t o adjust set tings by
following t his proce dure: Unplug t he steeri ng servo from the
receiver to avoid servo damage. Hold down either MODE or
INCR button while turning the power switch on. An LED se­quence will occur indicating yo u are in pi t tune mode . The
user set tings will be active, but the moto r will no t run and the
speed control will not respond to receiver signals. Turn the
speed control powe r off and bac k on to r esume normal opera­tion.

LED1: DRAG BRAKE contro l provides i mmediate br aking
action i n the neut ral zone. This gently slows the c ar down
when you l et off t he trigger . Drag Brake can provide a better
cornering approach . Higher values increase the degree of drag
braking.

QuickTune

Tekin’s Quic kTune electronic setup feature allows users to
change every critical operating parameter in a quick, easy, and
accur ate fashion. The basic oper ation is des cribed as :

• Use MOD E button to sc roll to a P rogram Feat ure.

• Use INCR ( increment ) button to view/adjust the Feature .

The B1 series has a built-in se lf-test mode that chec ks all major
systems on the spee d control. Bef ore using the self-test mo de,
be sure the rear whee ls are free to spin (off the ground) . To
activate the self-test, turn the speed control on, then press and
hold bot h MODE and INCR but tons simul taneously fo r 5
seconds . After 5 seconds, t he LEDs will ramp up in se ts of
two. Circuits inside the speed control are tested to see if any
proble ms have occ urred. If t he unit pass es self- test, the n LED3
wil l st ay on s tea dy.
If probl ems occur turn the po wer off to the unit and verify all
other co nnections are clean/ tight/cor rect (moto r, receiver, bat­tery, plugs, etc) . After veri fication, po wer the unit back on.

NOTE: Activating the self-test mode also resets all the user­program mable setti ngs and paramet ers to their defaul t values.
The use r’s radio cal ibration set tings are also reset to de faults.

SOLDERING, TOOLS NEEDED

SOLDERING CON T...

ATTACHING WIRES TO THE BATTERY:
The same techniques describe d in the prece ding sectio n may be
used to solder the wires to the battery connectors.

IMPORT ANT:

Take pr ecautio ns if removing f actor y battery
connec tors. Conne cting the bat tery backwar ds will c ause dam­age, and will void warranty. When s older ing connect ors to a
battery pack, cut only one wire of the battery pack at a time to
ensure that the expos ed wires canno t short to gether.

HINT: If you are using Dean’s connecto rs for both t he battery
and the mo tor, make sure that you have a mal e and a fe male
attache d to the spee d control wi res. That way, yo u cannot ac ci­dentall y connect the batter y to the mot or wires or vice ver sa.

1) If using a c onnector between batte ry and spee d control

make sure that the ends will be mat ed together correctly,
male t o female, and t hat the wir e colors match—red t o
red and blac k to black.

2) Solder the wires from the speed control to each of the

connectors, then solder wires from the battery to each
connector’s mate.

ATTACHING WIRES TO THE MOTOR:
The same t echniques described i n section 5 may be used to
solder the wires to the motor.

1) If using a c onnecto r between mo tor and spe ed control
make sure that the ends will be mate d together correctly,
male to female, and that the wire colors match—red to
red and blue to blue.

2) Solder the wires from the speed control to each of the
connectors, then solder wires from the motor to each
connector’s mate.

REMOVING WIRES:

1) Have a ho t iro n and the spe ed contro l secured. Cl ean the
tip of the iron and ap ply a small amount o f solde r. 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 so lder on the po st melts, pul l on the wire you wish
to remove.

HINT: If there is excess solder remaining on the post, you
may remo ve it by heat ing the po st until the solder j ust start s to
melt, then quickly tappi ng the spee d control agai nst the
workbench to knock off the exces s solder .

SOLDERING CON T...

Listed be low are a number o f tips to ensure t hat you will get
years of trouble- free perfor mance from yo ur Tekin spe ed
control.

LED2: NEUTRAL WIDTH adjusts your deadband a round
the neu tral point . A low neutr al width value pro vides more
sensit ive trigger response ar ound neutr al.
LED3: CURRENT LIMITER adjusts the throttle response
during acceleration to control annoying wheelspin. Low values
allow low amounts of current to pass to the motor, higher val­ues allo w higher amount s of cur rent. The top value (11) turns
OFF current limit.
LED4: PUSH CONTROL or ANTI-DRAG BRAKING
overcomes the natural drag of the motor when you return to
neutral. Racers refer to this as “creep” , this setting eliminates
the need to trim the throttle forward to create a coasting
(pushing) effect . Low values give you a shor t duration pus h,
higher value s a longe r duratio n push
LED5: BRAKE/REVERSE TYPE ** B1R ONLY**

1) Proportional Brake with Reverse Lockout (LED1 ON).
Propor tional brake will be applied dur ing rever se throt tle.

2) Forward to Brake to Reverse (LED1-2 ON). The car will

operate freely in forward and reverse. (Brakes to a stop
before switching into reverse)..

3) Proportional Brake with Reverse Delay (LED1-3 ON).

The car will only go in reverse if the trigger has been in
neutral for 1 second, otherwise it operates like
proportional brake with no revers e.

NO LIGHTS COME ON
Check f or dead batte ries. Chec k the connec tions bet ween the

the above procedure.
BATTERY POLARITY
It is e xtremely im portant to e nsure the bat tery pack i s
connec ted to the s peed contro l properly. Connecting t hem
backwards could ca use severe damage to the battery pack and/
or speed control.
DO NOT JAM THROTTLE
This will cause tre mendous reduc tion in run t ime and exce ssive
heat buil d-up.
RADIO INTERFERENCE
Try to kee p the rece iver at l east 1-2 inc hes away fro m any mo­tor or battery wires.
RECEIVER BATTERY
The built -in BEC (Bat tery Eli minator Ci rcuit) is str ong enough

RANGE
Transmit ter batte ries are low or damaged. M ismatc hed crys­tals. The three-wire cable from speed control to receiver may
also be too long; 6 inc hes is t he maximum. Thi s speed co ntrol
radiate s very lo w noise and you sho uld have no t rouble with
interf erence. If you do have inte rferenc e, mount the speed
control in the pan, and mount the receiver and antenna at the
top of the shock tower. Try to keep the receiver away from the
batteries, power wires, metal or graphite.

TROUBLESHOOTING

NOTE: Optio nal. Connec t a separate battery pac k to the

receiver using the “B” or “BAT” socket on your receiver. A
small switch should be used on the receiver pack to operate the
radio., and the receiver pack should have no more than 5 cells.
IMPORTANT: You must remove the red wire from the speed
control servo plug an d cover it with heat shr ink tubing.

The On-Bo ard Temperat ure Monito r works to provide you with
important feedback o n speed co ntrol tem perature, he lping you
to adjus t gearing and avoid long t erm heat damage. To us e;

1) The spe ed control must be c alibrated to your radio and
the radi o must be in the ne utral posit ion.

2) The middl e LED will be on st eady, and sho uld blink ou t
every 2 seconds.

3) At the moment that the center LED blinks out, one or
more of the other LED s will ligh t up.
