RC cars are becoming a widespread hobby, but like all electronic items, they can have issues. It is essential to maintain your RC car for it to last. One common problem that many RC car owners face is a stuttering car.\n\n\n\nSo, is your RC car stuttering? If your RC car is stuttering, here\u2019s a list of possible solutions to try:\n\n\n\nSwap the motor.Check the caps of the wires in the car to see if they\u2019re adequately soldered.Use a multimeter to test the conductivity of the Electronic Speed Control (ESC).Check the receiver in the RC car.See if the motor is stuck or \u2018cogged.\u2019Replace the batteries.\n\n\n\nThese six strategies are helpful for figuring out what the problem is and how to fix it. It\u2019s worth noting that some of them may require additional supplies (like a multimeter). This article will explain how to pinpoint the problem in your stuttering RC car and how to fix it.\n\n\n\nIf you are interested in checking out some of the latest RC cars that have tons of new features you can find them by clicking here. \n\n\n\nWhat to Do If Your RC Car is Stuttering\n\n\n\nFixing an RC car doesn\u2019t have to be a difficult task. The six solutions presented above hit a few different areas of the RC car that are vital to the successful running of it.\n\n\n\nSwap the Motor\n\n\n\nSwapping the motor may be one of the most straightforward solutions for a stuttering RC car.\n\n\n\nOften, people may look for other sources of problems when all it takes is a quick swap of the motor to see if that\u2019s the issue.\n\n\n\nTo swap the motor in your RC car, follow these steps:\n\n\n\nFirst, disconnect the power wires.Remove the gear cover.Remove the two motor screws near the motor.Remove the pinning gear from your old motor.Place the old pinning gear on the new motor.Place the screws back on the new motor and screw it into place.\n\n\n\nIf you would like to see how to replace the motor in your RC car, you can watch this video by HorizonHD called Electrix RC How-To: Motor Replacement.\n\n\n\n\nhttps:\/\/www.youtube.com\/watch?v=G3QhLCZDeMU\n\n\n\n\nUltimately, changing the motor will show you if the car\u2019s engine is the problem. If you replace the original engine with a brand-new one and you\u2019re still experiencing stuttering, then the problem is likely related to the ESC or some other part of the car.\n\n\n\nHowever, if a replacement of the motor leads to the solution of the problem and your car runs smoothly, then you can safely say that the motor was the issue.\n\n\n\nCheck the Caps of the Wires to See If They\u2019re Adequately Soldered\n\n\n\nWhen your RC car stutters, one of your first instincts should be to check the wiring. Like many electronic devices, short circuits can cause several issues. However, checking the wiring may be difficult if you\u2019re not used to tinkering with electronics.\n\n\n\nWhen checking the wiring of your RC car, make sure to:\n\n\n\nCheck for any cut or exposed wires.Check for any shorts in the wiring.Check to make sure every wire has a beginning and ending connection.\n\n\n\nIf you need help distinguishing which wires are essential in an RC car, you can refer to the video, How to Fix RC Motor from Cutting In and Out by Steve Andries.\n\n\n\n\nhttps:\/\/www.youtube.com\/watch?v=9Y5oIuY4VQk&pbjreload=10\n\n\n\n\nAs the video suggests, it\u2019s vital to unscrew the caps of the wires. Once unscrewed, you should have a clear view of the soldering job. If it\u2019s improperly soldered, the car will frequently stutter.\n\n\n\nChecking the soldering is a critical factor in RC maintenance, and it is a skill worth learning more about if you\u2019re a collector of these types of cars. The soldering job goes a long way in determining whether your RC will run fast and smooth or give you numerous headaches as it stutters around the driveway.\n\n\n\nUse a Multimeter to Check the Conductivity of the ESC\n\n\n\nYour Electronic Speed Control (ESC) regulates the motor of your RC car. So, if you\u2019re constantly flipping between high and low speeds, the ESC is the gadget that\u2019s doing all the work.\n\n\n\nSometimes, the ESC may not run as it should. This can be caused by a multitude of reasons, but what you should focus on is conductivity. It\u2019s possible that the ESC isn\u2019t working correctly because of short circuits.\n\n\n\nTo check to see if your ESC is working correctly, do the following:\n\n\n\nUsing a multimeter, you\u2019re going to check the ESC for any continuation of electrical current. Electricity comes in through one end of the ESC and then flows through small squares known as MOSFETS. Essentially, these squares turn the flow of electricity on and off. These currents then flow from these squares to the motor pads.\n\n\n\nPutting the multimeter in connectivity mode allows the user to touch each motor pad to see if there\u2019s any \u201ccontinuation.\u201d The device emits a small beep if it detects any continuation of electricity. If it beeps while the ESC is lying on a table connected to nothing, you know that there\u2019s a problem with the ESC.\n\n\n\nIf you want to get a more in-depth look at how a multimeter should work in this instance, there is a fantastic video called Is Your ESC Broken: How to Find Out by Joshua Bardwell you can refer to.\n\n\n\n\nhttps:\/\/www.youtube.com\/watch?v=NW4a3AnraVk\n\n\n\n\nCheck the Receiver Inside the Car\n\n\n\nOne of the things that many people don\u2019t stop to think about when using an RC car is how complex these tiny machines are. Even though people are used to advanced technology being the standard, everything needs to work just right for electrical devices to function correctly. For example, your RC car may have a problem with its receiver.\n\n\n\nAn RC car\u2019s receiver sits inside the vehicle and receives the signal from the remote control. It\u2019s what tells your motor to go, and it\u2019s also something that can break or stop working. If you\u2019ve exhausted all of the solutions above, then the receiver may be the culprit.\n\n\n\nIf the receiver is bad, the signal won\u2019t be strong from your remote control to the car. Consequently, the further the car gets away from you, the more it will start to stutter because of the weak signal.\n\n\n\nTo check to see if the receiver is the problem:\n\n\n\nOpen up your car and replace the receiver with the one you know for sure works.If it runs just fine and zips along with this new receiver, you know that this was the problem.Be sure to see how far your car can go before it loses signal and check for stuttering.\n\n\n\nSee if the Motor Is Stuck or \u2018Cogged\u2019\n\n\n\nAn RC car motor may be stuttering and not working correctly if it\u2019s jammed. Inside the RC motor lies what are known as \u201cmotor magnets.\u201d These magnets sit on either side of the engine. Sometimes, the motor gets stuck in between these magnets and it can cause several problems.\n\n\n\nLuckily, there are some steps you can take to check your motor for this issue.\n\n\n\nFirst, open the rotor. This is a tough one because figuring out how to take it off depends heavily on what type of motor you have. There is no clear-cut way to do this.Once you\u2019ve figured the first step out, locate the magnet and pry it out. A screwdriver does the trick quite well.Replace the magnets with thicker, neodymium magnets. These thicker magnets sit closer to the rotor. This decreases static, which is a good thing.Place transparent tape on the inside of the magnets. It\u2019s tricky because they\u2019re so small, so do this delicately.\n\n\n\nReplace the Batteries\n\n\n\nReplacing the batteries is one of the easiest fixes, but it\u2019s commonly not the culprit when it comes to stuttering. Typically, RC cars run on rechargeable lithium-ion batteries. These last for quite a while, depending on the brand, and knowing which type you have gives you a little bit more insight into what could be wrong with your car.\n\n\n\nIf you knowingly choose lower quality batteries, your stuttering problem could be caused by this factor. However, if you have some of the best RC car batteries around, then it\u2019s most likely not a battery issue.\n\n\n\nIn Conclusion\n\n\n\nIn conclusion, an RC car that\u2019s stuttering is a fixable problem. Utilize these steps, and you\u2019ll have your car zooming down the pavement in no time. And remember \u2013 regular maintenance of your RC car is the only way to make it last!
