Problem 1: ESC Is Not Powering On

ESC is of your vehicle is not working or powering up. Your axial ae-5 and axial ae-6 both can have this problem. Instead of freaking out, you can simply follow these steps. 


There is a number of reasons why ESC is not powering on. 

  1. The battery’s connections are incorrect.
  2. The throttle stick is “on”
  3. ESC is not getting any power from the receiver.


Several options are available to you to troubleshoot an ESC that’s not powering on. 

  • To begin with, verify that the battery is connected correctly. The ESC should be receiving power from the battery, so if it’s not getting power, it’s not going to turn on.
  • Additionally, make that the throttle stick is in the “off” mode before attaching the battery. If the throttle stick is in the “on” position, the ESC will not power on.
  • The ESC should be powered by the receiver, so make sure of that as well. To perform this, unplug the battery and then attach a servo tester between the receiver and the ESC. When you apply power to the receiver, the servo tester should light up.

Problem 2: ESC Is Not Calibrating Properly


If your ESC is not installed properly then this problem can cause. Also, this can cause by a damaged transmitter or a receiver.


If your ESC isn’t calibrating correctly, you can try a few different things to resolve the problem.

  • First, confirm that you are strictly following the owner’s manual guidelines. Sometimes a small mistake can cause the ESC to not calibrate properly.
  • Next, try calibrating the ESC using a different transmitter. If that doesn’t work, try calibrating it using a different receiver. 
  • If that still doesn’t work, then it’s possible there’s something wrong with the ESC and you’ll need to replace it.

Problem 3: ESC Is Overheating and Beeping Continuously

Proper taking care can fix this issue. It basically happens if you’re not taking care of your vehicle. Let’s see what steps can fix this issue and also why it happens.


You might be curious as to the cause why the continuous beeping of your ESC. Here is the possible reason for this unwanted situation. 

  1. A lack of cooling airflow usually causes this. 
  2. The wire of the cooling airflow is not connected properly
  3. Or the wire is probably damaged.
  4. Overheating is one of the many issues a loose connection can create.

If your arrma ESC is blinking red, then the solution would be to check the battery. Check to see if the battery is charged all the way.


If your ESC is beeping continuously, it’s likely overheated at this point. Therefore, the first action you should take is to try and find the source of the heat. This is the solution to the issue.

  • The best way to fix it is by checking the fan and ensuring it’s running correctly.
  • Maybe there’s something blocking the airflow, or the ESC is getting too much power.
  • Checking the wire connections comes next if the fan appears to be functioning normally. Verify that they are linked properly and are free of damage or corrosion. 
  • If you are unable to resolve the issue, you might need to increase cooling capacity or reduce power output.
  • You can also make sure that your ESC is properly lubricated. This will keep it functioning smoothly and at a cool temperature.
  • And finally, always make sure your connections are tight and secure. 
  • If everything looks good, then you might need to replace the ESC.

Trying hard to move your car but it’s not moving. The problem is quick and simple to resolve. Here is the problem and its solutions.


If your ESC is not responding to throttle input, this can cause for these reasons:

  1. Throttle contact is probably jammed
  2. The faulty motor is another reason 


If your ESC is not responding to throttle input, You can take a few actions to resolve the issue.

  • First, check the throttle range on your transmitter and ensure that it is in the appropriate setting. You can easily set up your axial ae-5 in the correct position.
  • If it’s set correctly and your ESC is still not responding, try cleaning the throttle contacts with a bit of electrical contact cleaner.
  • You might need to have the ESC replaced if that does not help.
  • But before you go and do that, make sure you’ve checked all the other possible causes, like a bad connection or a faulty motor.

Problem 6: ESC Is Shutting Down

I know, how annoying it is when ESC shuts down suddenly. But, I’m going to share the same fixes I followed when I had the same problem. Let’s see. 


While running your rc car it shuts down sometimes. This is very annoying when it happens. But what might be the cause of this issue?

  1. It might result in the battery not being fully charged.
  2. The connections are loose 
  3. Maybe dirt is blocking the way


Among the most typical issues with the ESC is that it will simply shut down. There are a few things you can do to try and fix this:

  • Make sure that you’re using the proper battery and that it’s fully charged.
  • Make sure the connections are secure and that there’s no dirt or debris blocking the airflow.
  • Consider using a cotton swab soaked in rubbing alcohol to wipe the battery connections.
  • If all else fails, try resetting the ESC by disconnecting it from the motor and then reconnecting it.

Frequently Asked Questions (FAQs)

Why Is My Esc Flashing?

If there’s a short in your wiring, the ESC will flash. This is because the battery is sending a signal to your ESC that it’s being charged or discharged. This can happen if you’re using a cheap battery, or if you have a bad connection in your wiring. If there’s no external cause for the flashing, it’s time to replace your ESC.

Why Is My Esc Beeping?

The engine is overheating, according to the Esc Beeps. It serves as a reminder that your car has to cool off before continuing. If you hear this beep, go slowly and stop as soon as you can. You may need to take a break in your journey, or even park at a gas station and let the engine cool off.

Why Won’t My Esc Start?

First, you should check that the battery connections and connections to the battery are secure. Installing new connectors can be required if you have an early model. If this does not fix the problem, you can try cleaning the connectors and cables with a soft cloth. If this does not help, you should contact the manufacturer for help.
