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
roll-over.

SAFETY NOTE

WARNING: This is an extremely powerful brushless motor system. We strongly

recommend removing your pinion gear for your own safety and the safety of those around
you before performing calibration and programming functions with this system. Please keep
your hands, hair, cloth, clear from the gear train and wheels of an armed high performance
system.

WATER & ELECTRONICS DON'T MIX!

Never allow water, moisture, or other foreign materials to get inside ESC, motor, or on the
PC Boards. Water damage will void the warranty!

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.

From this point on, when you connect batteries and turn on the switch, the ESC will give the
initialization tone and flash, and the arming tone will ring second or two later. If the ESC is
programmed for the Auto-Lipo setting, it will beep the number of cells in you Lipo pack
between the initialization tones and the arming tones. After the arming tone plays, the ESC will
ACTIVE and will respond to the throttle application.

ESC PROGRAMMING
