Don’t mash the throttle all the way, accelerate slowly and make sure the motor spins. If you accelerate slowly and the motor doesn’t
spin you can check your connections etc. If you mash your throttle and something is not right, you might blow up the ESC.
● In our testing (which means using equipment that works 100% and proper installation) we’ve had very few issues. It’s not normal to
have glitches or low power or anything of that type. Anytime there is a glitch or stutter while you are driving, you need to stop and
find out the cause, it probably means there is a faulty connection somewhere. Things will not self-repair magically, if there is an
issue, restarting the ESC or waiting for 5 minutes before driving again is not a solution, doing that will most likely cause the ESC to
stop working very soon.
● The ESC has an overheating protection that will cut off all the power to the motor when a certain limit is reached.
● The ESC battery low voltage cut-off will decrease the motor power when the pre-set voltage limit is reached.
● Bad connections can cause overloads and/or ESC resets that can cause the ESC to lose power and/or malfunction.
Things to think about :
● Good tight electrical connections all around.
● Enough give in the wires to follow the chassis flex, especially if you attach the wires to the chassis.
● Don’t attach the sensor wire with the motor wires or route it near to the motor wires as it can cause interference
to the sensor signal
● The sensor connection is critical, you need to check the wire and connections regularly.
● Use large and tight connectors for the battery, connectors will loosen quickly.
● The BEC circuit that supplies power to the receiver and servo also powers the ESC itself and the sensor circuitry. It means that if
you have faulty equipment or too much load on the receiver side (receiver, servo, transponder, fans, etc.) it can cause the ESC to
malfunction or fail.
● Depending on the servo type you use it can draw 2-3 times more current than another servo. This can overload the ESC and
cause it to malfunction.
● Receivers with extra functions like fail-safe, telemetry, etc. have been known to make issues.
● Power everything ON as if you were going to drive the car, before plugging in the USB cable.
● Plug in the USB cable to the ESC and your PC (micro USB connector for the ESC).
● The first time you connect an HMX to your PC, it will install some drivers automatically for the HMX to be recognized. For this to
work you need to be connected to the internet.
● After you see the Windows message that a new device has been installed, you can launch the PC app, select the COM port and
press CONNECT.
● If there is a connection issue you also need to disconnect the USB to reset everything, not only switch the ESC OFF.
