9) Once calibration is complete, ESC will arm
4.0 Using your ESC
Once the battery connector is installed and ESC is connected and calibrated to your radio,
the ESC will arm once the battery is plugged in. ere is no on off switch on this ESC, so
the battery must be unplugged after use. Full programming can be done on the computer via
the Castle Link© software and USB programmer. Minimal features are available with stick
programming.
Special tuning modes
Holmes Hold (active brake): is feature allows for a much stronger brake at neutral throttle
position. It is controlled by the % of drag brake selected. If this setting is turned too high, it
will cause buzzing and motor creep. When you enable Holmes Hold, try turning down the drag
brake if you experience these problems.
rottle Damping: is feature allows for a smoother throttle action, with independent
throttle up and down control. When activated, it smooths out throttle inputs. rottle Up
Damping can slow down throttle increases. is can be useful for preventing broken drivetrain
parts. rottle Down Damping slows down the release of throttle, which can be useful to
prevent jerky stops with light rigs or worm gear axles.
Entering stick programming mode:
Plug a battery into the ESC and hold full throttle on the transmitter before the ESC arms, or
have a helper hold full throttle before you plug in the battery. After a few seconds you will get
the four rings in a row signaling full throttle calibration. Keep holding full throttle. After a few
more seconds, you will hear another four rings in a row. After the second group of four rings,
relax the throttle to neutral. If you have successfully entered programming mode, the ESC will
beep twice, pause, and repeat
the two beeps.
e programming sequence is always presented in sequential order and always starts with
the first setting (No cutoff voltage) within the first section (Cutoff Voltage). e first beep(s)
signifies which section of the programming you are in and the second beep(s) signifies which
setting is waiting for a “yes” or “no” answer
Stick Programming
Full throttle = “yes”; Full Reverse = “no”

5.0 Troubleshooting
•ESC buzzes or at neutral
-Turn off Holmes Hold, or turn down drag %
•Drag brake or rottle Damping doesn’t work properly
-Recalibrate ESC to radio
-Ensure that neutral setting on radio is adjusted properly
-Reprogram ESC
•No lights on ESC
-Check that battery is plugged in, and polarized correctly
•No power to motor
-Ensure motor is plugged into ESC properly
-Ensure motor is in good condition and brushes are properly
operational
-Ensure Battery is plugged into ESC properly
-Ensure ESC is arming and plugged into RX properly
-Ensure Battery is fully charged
•ESC wont arm (all lights blinking)
-Double check that radio is on, and that ESC is plugged into RX
properly
-Try adjusting neutral on your transmitter, or reversing your throttle
channel
