ESC PROGRAMMING
The ESC has two programmable items, you can easily program them via jumper caps (as explained and shown below).
The first row is “Drag Brake”, connecting one jumper cap
to the two pins on the left will allow you to have 100% drag
brake; connecting it to the two pins on the right will allow
you to have 0% drag bake. The drag brake is 100% by default.
Note: 100% drag brake are applicable to crawlers, 0% drag
brake is applicable to boats, you can adjust it as per the
actual condition. When setting the “Drag Brake” to 100%, the
“Maximum Reverse Force” will be 100%, when setting to “0%”,
the “Maximum Reverse Force” will be 25%.
The second row is “Battery Type”, connect the other jumper
cap to the two pins on the left when you’re using a LiPo pack,
and connect it to the two pins on the right when you’re using
a NiMH pack. The “Battery Type” is “LiPo” by default, you can adjust it as per the actual condition.
PROTECTION FUNCTIONS
1. Low-voltage Cutoff Protection
When the “Battery Type” is set to “LiPo”, the cutoff voltage for one cell is 3.2V. That means when you’re using a 2S LiPo, the cutoff voltage for the
pack will be 6.4V; the cutoff voltage for the pack will be 9.6V when you’re using a 3S LiPo. When the “Battery Type” is set to “NiMH”, the cutoff
voltage (for the pack) is 4.5V.
The ESC will have the output when it detects the battery voltage has reached the threshold for 2 seconds, and cut off the output 2 seconds later. It
will resume the 50% output when the throttle trigger is released to the neutral position, cut off the output 2 seconds later, resume the 50% output
(when the throttle trigger is released to the neutral position), and then cut off the output 2 seconds later, ......this will continue (unless the battery is
removed or changed). The Red LED flashes a single flash that repeats when the LVC protection is activated. Please try to charge the pack or change
another one when the protection is activated, as long-time usage will cause the pack to over-discharge and be damaged.
Note: please check if you’ve set the “Battery Type” properly when the low-voltage cutoff protection can easily get activated. If you’ve set the
“Battery Type” correctly, then the issue is probably caused by the poor discharge capability of the battery. In that case, please try with a battery with
better discharge capacity to see if the problem can be solved.
2. Thermal Protection
The ESC will directly cut off the output and the Red LED will flash a double flash that repeats when its internal temperature reaches the value
(105°C/221°F) preset by the factory. You can use it again when the ESC temperature gets below 60°C/140°F.
Note: if the thermal protection can easily be activated, then the issue in general is caused by improper configuration. That’s the ESC cannot meet
the demand of the vehicle. In that case, please reduce the vehicle’s load or change another ESC with higher continuous current.
3. Throttle Signal Loss Protection
The ESC will immediately cut off the output and the Red LED flashes rapidly when it detects that the throttle signals have been lost for 0.1 second.
Note: because the ESC works based on the throttle signals received from the transmitter, so its performance (after losing throttle signals) is closely
related to the setting of your transmitter.
TROUBLESHOOTING
PROBLÈME
RAISON POSSIBLE
SOLUTION
The ESC was unable to start the status LED
and the motor after it was powered on
No power was supplied to the ESC.
Check if all ESC & battery joints or connections have
been well soldered or firmly connected
The ESC switch was damaged.
Replace the switch
The ESC was unable to start the motor but
the Red LED flashed rapidly after it was
powered on.
The neutral position on the transmitter was moved or
changed.
Re-calibrate the throttle range or fine tune the throttle
trim to make the neutral position on the transmitter match
the existing neutral position of the ESC.
The throttle control cable was reversely plugged in.
Check if the throttle cable has been reversely plugged in.
The vehicle ran backward when you pulled
the throttle trigger towards you.
The motor-to-ESC wiring order was incorrect.
Swap the two wires from motor to ESC.
The motor suddenly stopped spinning in
operation.
The throttle signals were lost.
Check the transmitter and the receiver.
The LVC protection or the thermal protection was
activated.
The Red LED would flash a single flash repeatedly. Please
check the battery voltage and the ESC temperature.
The motor accelerated suddenly, stuttered or
stopped during the starting-up process.
The discharge capacity of the pack was insufficient.
Change another pack with better discharge capability.
The RPM was too high, the gear ratio or FDR was
improper.
Change another motor with lower RPM or increase the
gear ratio or FDR.
