INTRODUCTION
SkyRC introduces the economical, easy to use Toro 1 cell Brushless System. This ESC comes
with built-in DC/DC inverter (DC/DC booster) and DC/DC converter. This innovative technology
allows drivers to power their vehicle’s electronics on a single 1 cell Li-Po battery pack without
installing additional external boosters or receiver pack and also the ESC can be powered by 2
cells Li-Po without external BEC.
Toro 1 cell ESC is also compatible with all sensorless brushless motors and most sensored
brushless motors with timing or without timing.
Toro 1 cell ESC is optimized for 1 cell racing and features a low-profile heat sink for easy
installation in 1/12 scale vehicles with space constraints.
This ESC also comes with a cooling system to support 2S LiPo, 1/10 scale vehicle. You can
use thermal double-sided adhesive tape(included) to mount the cooling system on top of ESC.

NO REVERSE VOLTAGE!
Reverse battery polarity can damage ESC & void warranty. Disconnect battery immediately
if a reverse connection occurs.
DISCONNECT BATTERIES WHEN NOT IN USE
Always disconnect the battery pack from the speed control when not in use to avoid short
circuits and possible fire hazard.
TRANSMITTER ON FIRST
Turn on the transmitter first THEN turn on the speed control.
INSULATE WIRES
Always insulate exposed wiring with heat shrink tubing or electrical tape to prevent short
circuits, which can damage ESC.
TIMING PRODUCES DANGEROUSLY HIGH SPEED
When Toro's electronic motor timing is enabled, the vehicle speed can be increased
dramatically. Please take extra precautions.
TIMING INCREASE ESC & MOTOR'S TEMPERATURE.
Electronic motor timing will increase the temperatures of ESC and brushless motor. Use
extreme caution when setting up and testing your application to avoid overloading
and overheating.
BEFORE YOU BEGIN
1)Plan Speed Control Placement
Choose a location for the speed control that is protected from debris. To prevent radio
interference place the speed control as far away from the radio receiver as possible
and keep the power wires as short as possible.Select a location that has good airflow
ventilating. If the ESC gets air flow, it will run cooler; and that means, it will be
more efficient.
2)Mount Speed Control in Vehicle
Use double-sided tape to mount the speed control in vehicle(do not use CA glue).
Secure power capacitor module to chassis. Yo u can use double-sides tape or a
tie wrap to mount power capacitor to the vehicle's chassis or shock tower. Module
can also be tie-wrapped along the power wires.
Use double-sided tape to mount the switch where it will be easy to access.Select
a position where it will not get damaged or get switched OFF

3) Soldering
Cut the ESC's BLUE, YELLOW & ORANGE silicone motor power wires to the desired
length and strip about 3.2mm-6.35mm (1/8”-1/4”) of insulation from the end of each
wire. “Pre-tin”the wire by heating the end and applying solder until it is thoroughly
covered.
CAUTION: By very careful not to splash yourself with hot solder.
Place the ESC's BLUE Phase ‘A’ motor wire onto motor's ‘A’
Use soldering iron to apply heat to exposed wire; begin adding solder to tip of soldering
iron and wire. Add just enough solder to form a clean and continuous joint from the
plated area of the solder tab up onto the wire. Solder the ECS's YELLOW Phase
‘B’ motor wire to the motor's ‘B' solder tab and Solder the ESC's ORANGE
Phase ‘C' motor wire to motor’s ‘C’ solder tab.

When you enter programming mode the ESC will emit a sequence of beeps and LED flashes
that tell you which programming step you are in. There are two parts to the beep sequence.
The first set of beeps indicates the 'Setting Number (Question), e.g. Brake/Reverse Type, and
the second set of beeps indicates a Setting Value, e.g. Reverse Lockout. Answering "No" to a
Setting value will cause the ESC to ask for the next value in that section. After a "Yes" answer
is accepted, the ESC knows you aren't interested in any other option in that section, so it skips
to the first option in the next section.
Note: I f you an swer " no" to a ll Set ting Value s for a pa rtic ular Setting Number, the ESC

2)Auto-Lipo(D)*
When answering a question, you will need to move the trigger to yes (full throttle) position or
the no (full brake) position and keep it there for about 3 seconds. When the ESC has accepted
your answer it will confirm your reply by flashing the LED and emitting a beeping tone.
Release the trigger allowing it to go to Neutral to confirm that you are ready for ESC to ask
you next question. You are not required to continue through all eight programming options. For
example, if you wish only to change the Brake/Reverse Type (Option 1) then after
programming that setting you can disconnect power from the ESC and you're ready to run.
Disconnecting the controller in the middle of programming simply retains the values for the
remaining programming options that were previously set up.

TROUBLE SHOOTING
Problem: My TOR O ESC ma y or may n ot arm , but it w ill no t cali brat e to my transmitter
Solution: Most ca libr atio n issu es can b e solv ed by ch angi ng settings on the transmit ter.
Make su re you h ave bo th you r thro ttle a nd bra ke endpoints (called EPA or
ATV on your radio) on the thro ttle c hann el out t o betw een 10 0 to 120 %. Mak e
sure if y ou hav e a Futa ba or Fu taba m ade tr ansmitter to have the throt tle
channel set to the reversed position.
Problem: My ESC ca libr ates f or the f ull th rott le and f ull br ake positions but won't
calibrate to the neutral throttle position. (Orange LED keeps flashing)
Solution: Try moving the throttle trim one way, then the ot her (usu all y towards the
thro ttl e sid e is best). If your transmitter has a 50/50 and 7 0/3 0 set tin g for the
thro ttl e, se t it for 50/50 and retry calibration. Also, if you have changed the
dead band to a narrower band you may wan t to try going back to the "normal"
sett ing.
Problem: Spee d Con tro l Run s Exc ess ive ly Ho t
Solution: Reduce timing level setting in ESC. Electro nic moto r timing set too high.

Ver. 1.1 Ver. 1.1
Problem: My vehicle acts like it has "turbo lag" (poor acceleration/punch fo r the firs t
few feet or yards)
Solution: Make s ure you' re using high quality batteries and a battery connector capable
of high amp flow (40-100 amps). This behavior is very typical of a battery pack
that is having diffic ult y pro viding the power your vehicle/system requires for
top performa nce . Use copper bars to connect cells rather than welded tabs.
Copp er ba rs have a much lower resistance.
Problem: My bat ter y pac k is plugged into the ESC and nothing is wor kin g
Solution: Make sure the ESC's receiver plug is plugged into channel 2 on the receiver,
and that it's plugged in with the correct orientation. Double check your solder
conn ect ions on th e batter y plug, and make sure the battery is showing good
volt age .
Problem: Timing Does Not Operate Properly
Solution: Set motor rotation to counter-clockwise–Electronic motor timing advancement
only functio ns in counter -cl ock wise rot ation di rection. You may solve this
prob lem b y disabl e motor timing.
Problem: The ESC shut off and red LED flas hing
Solution: The ES C has buil t in thermal protection circu itr y to protect the ESC from
bein g dam age d dur ing running. If the thermal protection shuts the ESC off, the
redLED will flashing. Check the KV value of motor and make sure the pinion is
not too large for the motor. On ce th e ESC cool down, it will resume working.
