    What to do if the LED is flashing on the Helion Dominius10SCV2 Motorized Toy Car ESC?
    • A
      Alexander TylerAug 1, 2025
      If the Electronic Speed Control (ESC) LED is flashing on your Helion Motorized Toy Car, it indicates a protection mode is active. One flash per second means low voltage cut-off is active. Two flashes per second indicate ESC over-temperature protection. Three flashes per second signal ESC over-current protection. If you see any combination of these flashes, turn the ESC off, change the battery, and allow the system to cool down before using it again. Also, ensure your ESC is in the correct running mode for the type of battery you are using.

    Why my Helion Dominius10SCV2 Motorized Toy Car slowed down drastically during a run?
    • C
      Chelsea PachecoAug 6, 2025
      If your Helion Motorized Toy Car slowed down drastically during a run, it could be due to several reasons. The battery voltage may be too low, activating the Low Voltage Cutoff (LVC). In this case, charge or change the batteries. Alternatively, the ESC over-temperature protection may be active; turn off the ESC and allow both the ESC and motor to cool down before running again. Another possibility is that the ESC over-current protection is active, so change operating conditions to ones that are not as hard on the electronics, for example, move from grass to asphalt. Finally, consider reducing the pinion gear size on the motor to reduce the load on the ESC.

    What to do if reverse is not working on my Helion Dominius10SCV2?
    • C
      Christina OrtizAug 12, 2025
      If the reverse is not working on your Helion Motorized Toy Car, it might be because the reverse mode has been disabled in the ESC. Follow the setup instructions to turn it back on. Alternatively, the ESC might have been improperly set to the transmitter; reset it to the transmitter, ensuring the throttle channel is set to reverse for non-Futaba transmitters. Also, check if the EPA on the transmitter has been turned down for reverse; adjust the EPA to 100% and reset the ESC to the transmitter.

    Why my Helion Dominius10SCV2 motor only goes in reverse?
    • S
      Summer KellyAug 19, 2025
      If your Helion Motorized Toy Car motor only goes in reverse, or goes in reverse when you pull the trigger to go forward, it could be due to a few reasons. First, check if the throttle channel is not set to reverse; unless using a Futaba radio, set the throttle channel to reverse and reset the ESC to the transmitter. Another cause might be that the motor is connected to the ESC improperly; switch any two motor wires. Lastly, the EPA on the transmitter might have been turned down for reverse; adjust the EPA to 100% and reset the ESC to the transmitter.

    How to fix Helion Motorized Toy Car ESC when it will not set to the transmitter?
    • E
      Elizabeth RobersonAug 26, 2025
      To address the issue of the ESC not setting to the transmitter on your Helion Motorized Toy Car, try re-binding the receiver and transmitter. If that doesn't work, ensure that the throttle channel is set to reverse unless you are using a Futaba radio. Also, replace the batteries in both the car and the transmitter, as dead batteries could be the cause. Check that the transmitter trims and EPA’s are not too far out of range for the ESC by ensuring the throttle/brake trim is centered and adjusting the throttle and brake EPA’s to the maximum. Finally, make sure that the transmitter is not too close to the vehicle, hold the transmitter farther away from the vehicle.
