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 nine 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.


The TORO SC comes with a 30mm x 30mm x 10mm 5V Brushless fan.
Should the fan need replacement, simply unplug the fans power wire
from the TORO SC, remove the 4 screws that secure the fan and
remove the fan cover.

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



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


The TORO SC 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 4S 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

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.

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)

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
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.

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

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
