ESC Programmable Items

To set the programmable items, use the LED program box. The instructions can be found on the next page.
NOTE: The black shaded boxes in the following table are the default values of programmable items.
1. Cutoff Voltage: This function is mainly to prevent the irrecoverable damage caused by over discharge of
LIPO Cells. If the voltage protection is turned on, the ESC will monitor the battery voltage all the time during
operation. Once the voltage is lower than the set threshold value, the power output will gradually reduce to
50% of the normal power within 3 seconds, and the power will completely cut off after about 40 seconds.
When entering the low-voltage protection, the red LED will blink in the sequence of “−, −, −” . When set
to no protection, the ESC will not cut off power due to low voltage and is only intended for NiMH batteries.
When using LIPO Cells, you must have the cutoff voltage turned on, otherwise the battery may be damaged
due to over discharge. The low, medium and high options correspond to 3.0v/3.2v/3.4v respectively. For
NiMH batteries, it is recommended to set this parameter to no protection.
2. Motor Rotation: When the motor shaft is facing the user and the throttle trigger is squeezed, like you would
do to drive forward, the shaft turns clockwise when set to CW and counterclockwise when set to CCW. If the
vehicle drives in reverse when you are giving it radio input to drive forward, you can change the motor rota-
tion in the ESC. We recommend checking the radio’s throttle reverse function first (see PG. 2).
3. Drag Brake Force: Drag brake represents an automatic braking force on the motor when the throttle trigger
moves from a non-neutral position to the neutral position. There are 6 options of drag brake force to adjust,
"Disabled" means the drag brake force is 0; the corresponding drag brake force increases from level 1 to level
5. Select the appropriate drag brake force according to you preference.
4. Drag Brake Rate: This controls how abruptly the drag brake force increases from zero to the set value when
the radio trigger enters the neutral range, commonly called slow brake. This value has 5 options to adjust.
The higher the level is, the more abruptly the drag brake reaches its full drag brake force value. Level 3 is
recommended to can make the vehicle stop with more stability.
5. RPM/Throttle Matching: Permanently Enabled
When the resistance of the vehicle changes, the ESC will automatically adjust the amount of torque to
adequately match the current speed, providing smooth and predictable performance.
6. BEC Voltage: 7.4V at 4A
