  If the steering and motor aren't working, first, try recharging or replacing the battery. If that doesn't work, make sure you've selected the correct model memory on your transmitter. If the issue persists, you may need to bind the transmitter to the receiver again. Refer to your transmitter and receiver manuals for instructions on these steps.

  If there's no motor function, audible tone, or LED when the ESC is on, it could be due to a battery or connection issue. Try recharging or replacing the battery and ensure all connections are secure. It could also indicate a damaged ESC/switch, in which case you should repair or replace the ESC switch/ESC. Another possibility is a damaged motor, which would also require repair or replacement.

  If your vehicle isn't reaching full speed, the issue might stem from the battery. Try recharging or replacing it. Alternatively, the transmitter or ESC calibration could be off. Adjust the throttle travel and other throttle settings on the transmitter/ESC, and then repeat the ESC Calibration Procedure.

What to do if the motor stops and the LED blinks on my Horizon Hobby Spektrum Firma 40A Brushed Smart ESC?

  If the motor stops and the LED blinks, it could be due to low voltage protection. When this happens, recharge or replace the battery. Another cause could be overheat protection. When the LED blinks, let the motor and ESC cool down, and consider changing your setup or gearing to prevent overheating in the future.

What to do if the steering servo operates but the motor does not run on my Horizon Hobby Spektrum Firma 40A Brushed Smart ESC Controller?

  If the steering servo works but the motor doesn't run, the motor may be damaged. Test the motor independently from the rest of the vehicle system and repair or replace it as necessary. Another potential cause is incorrect transmitter/ESC calibration. You may need to adjust the throttle travel or other throttle settings on the transmitter/ESC. Then, repeat the ESC Calibration Procedure.
