Solution: Try moving the throttle trim one way, then the other (usually towards the
throttle side is best). If your transmitter has a 50/50 and 70/30 setting for the
throttle, set it for 50/50 and retry calibration. Also, if you have changed the
dead band to a narrower band you may want to try going back to the "normal"

Problem: My TORO ESC may or may not arm, but it will not calibrate to my transmitter

Thermal Overload Protection



The TORO 1 cell Brushless ESC is guaranteed to be free from defects in materials or
workmanship for a period of 120 DAYS from the original date of purchase (verified by dated,
itemized sales receipt)
. Warranty does not cover incorrect installation, components worn by
use, damage to case or exposed circuit boards, damage due to timing, damage from using
more than 3 Li-Po cells input voltage, cross-connection of battery/motor power wires,
overheating solder tabs, reverse voltage application, improper use or installation of external
BEC, damage resulting from thermal overload or short-circuiting motor, damage from incorrect
installation of FET servo or receiver battery pack, tampering with internal electronics, allowing
water, moisture, or any other foreign material to enter ESC or get onto the PC board, incorrect
installation/wiring of input plug plastic, allowing exposed wiring or solder tabs to short-circuit,
or any damage caused by a crash, flooding or natural disaster. Because SKYRC has no
control over the connection & use of the speed control or other related electronics, no liability
may be assumed nor will be accepted for any damage resulting from the use of this product.
Every SKYRC speed control & motor is thoroughly tested & cycled before leaving our facility
and is, therefore, considered operational. By the act of connecting/operating speed control,
user accepts all resulting liability. In no case shall our liability exceed the product's original
cost. We reserve the right to modify warranty provisions without notice. This product is not
intended for use by children under 14 years of age without the strict supervision of an adult.
Use of this product in an uncontrolled manner may result in physical damage or injurise take
extra care when operating any remote control vehicle.

Solution: Most calibration issues can be solved by changing settings on the transmitter.
Make sure you have both your throttle and brake endpoints (called EPA or
ATV on your radio) on the throttle channel out to between 100 to 120%. Make
sure if you have a Futaba or Futaba made transmitter to have the throttle
channel set to the reversed position.

Solution: Make sure 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

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
connections on the battery plug, and make sure the battery is showing good

To conform to ROAR's Sportsman Class racing rules and help race organizers monitor driver
compliance in non-timing race classes, Toro 1 cell ESC has included a feature in this speed
control that indicates when the ESC has its electronic motor timing advancement feature
At all times when the speed control is powered ON and the Dynamic Motor Timing is turned
ON and set to a level greater than zero timing advance, the ESC's white status LED will be
illuminated during normal operation.


Problem: My battery pack is plugged into the ESC and nothing is working

Problem: My ESC calibrates for the full throttle and full brake positions but won't
calibrate to the neutral throttle position. (Orange LED keeps flashing)

that is having difficulty providing the power your vehicle/system requires for
top performance. Use copper bars to connect cells rather than welded tabs.
Copper bars have a much lower resistance.

Solution: Set motor rotation to counter-clockwise–Electronic motor timing advancement
only functions in counter-clockwise rotation direction. You may solve this
problem by disable motor timing.

Solution: Reduce timing level setting in ESC. Electronic motor timing set too high.
Increase gear ratio/Reduce pinion.

Problem: Timing Does Not Operate Properly

Problem: My vehicle acts like it has "turbo lag" (poor acceleration/punch for the first
few feet or yards)

Motor Type

Sensored and sensorless Brushless Motors

Problem: Speed Control Runs Excessively Hot

Solution: The ESC has built in thermal protection circuitry to protect the ESC from
being damaged during 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. Once the ESC cool down, it will resume working.

Problem: The ESC shut off and red LED flashing
