Whether you are a hobbyist or just recently got a fun new RC car for the kids, a great day at the park with your favorite remote control cars can be ruined by poor response, or even worse \u2013 a car gone rogue. There are a number of reasons why your RC car might act like it has a mind of its own.\n\n\n\nWhy does my RC car go by itself? This depends on a number of factors, but the most likely culprits are:\n\n\n\nSomeone Else Has The Same Transmission Frequency \tThere is Interference in Your Area \tDamaged or Frayed Wires \tPoor Connections in the Servos \t\n\n\n\nWhen we\u2019re talking about your car \u201cgoing by itself,\u201d this encompasses full-throttle motion in either direction, reversing when you\u2019re in drive, slight rolling when you\u2019ve come to a stop, and any other motion that you\u2019ve not initiated. Your mind may immediately jump to \u201cIt\u2019s haunted!\u201d but rest assured, the spirits of the other world are probably not playing with your RC car. Here are a few things that it might be.\n\n\n\nIf you want to see what new RC cars have to offer you can check out all of the features and even find great prices by clicking here. \n\n\n\nSomeone Else Has The Same Transmission Frequency\n\n\n\nThe most likely scenario if your car is actually driving, turning, and acting possessed is that someone has intercepted your transmission frequency. Yes, it\u2019s possible that you\u2019re being trolled, but it might also just be an accident. Especially with toy remote control cars, the frequency span is fairly common.\n\n\n\nMost remote control toys will run on a frequency of 27 to 49 Megahertz. So, if you\u2019re driving a toy RC car in the park where others have their own RC models, cars, or otherwise, the transmissions can get confused. Yes, your car should be tuned in to your controller better, but there are a couple of reasons someone can supersede your control and how you can regain the wheel:\n\n\n\nIf your batteries are starting to die, either in the car or the controller, and someone on your frequency has more power, they will be able to control your car. Collect your car, turn it off, and replace the batteries. This should allow you control of your RC car again. Otherwise, it might be something else.\n\n\n\nIf your RC car has an option to switch between Channel and Frequency, switch it up. You might \tbe able to knock your would-be interceptor off the controls. Most \tinexpensive cars won\u2019t have this, but just in case, it\u2019s best to change up your wavelength. Make sure that, when you make the change, your car and transmitter change to the same frequency.\n\n\n\nMove further away from other cars. A distance of 75 to 100 feet should provide you with enough distance to gain control of your own car. If you and another member of your party are crossing signals, you should adjust one car\u2019s frequency to gain control over your own cars. \t\n\n\n\nIt might be time to head home. As disappointing as it is to cut a fun day of RC driving short when you can\u2019t get someone else off your channel, it\u2019s not about to \tget better. Hopefully, there is somewhere else you can drive without interference.\n\n\n\nThere is Interference in Your Area\n\n\n\nAside from another remote control vehicle in your area, there is a chance for interference from other sources as well. If your RC car is going by itself, here are a few things that may affect your radio signal and why:\n\n\n\nChain link fences - As radio waves interact with a chain-link fence, they can pass through the holes. However, they diffract to bend around the metal. As they bend, they circle back around and cancel themselves out. This leads to poor control over your car. \t\n\n\n\nCB radio signals - These days, most CB radios run at between 72mhz and 75mhz with a crystal \tsystem, and that should remove the risk of CB interference. That, unfortunately, doesn\u2019t mean the 27 wavelength is clear of all traditionalists. You may run into a rogue CB wave.\n\n\n\nRadio or TV antennae - Most radios and TV signals are high enough to leave your car alone. A rogue signal, like CB, could derail your plans for a fun day. Low \ttech radios with antennae or old school portable TVs could be trailing low enough frequencies to mess with your car. \t \tNeon or fluorescent lights - Neon and older fluorescent lights emit \telectromagnetic wavelengths that can interfere with radio frequencies. You\u2019ll find that they can affect not only your RC car \tbut AM\/FM radio signals, as well. \t\n\n\n\nSteel structures - Steel is a great conductor, which means that any electromagnetic or radio wave frequency will be absorbed by the metal. The more steel that was used in the construction of a nearby building, the less likely you are to have a good signal for remote control in that area. You will also find that standard radio stations don\u2019t play as well for the same reason.\n\n\n\nDamaged or Frayed Wires\n\n\n\nUp until now, we\u2019ve mainly addressed issues in common RC cars; however, more specific to hobby RC cars, you may need to open up your transmitter and check for fraying or damaged wires. That\u2019s not to say a toy RC car may not be suffering from the same issue.\n\n\n\nHowever, unless you have practice in working with RC transmitters, please don\u2019t fiddle with the controls. Especially with a cheaper toy, it may be easier to return it and find one with a different colored frequency sticker.\n\n\n\nBack to fixing a damaged or frayed wire, poor connectivity will result in erratic behavior on the part of your car. As long as you are comfortable fiddling with your own controller, you may need to solder the wire back into place. A particularly frayed wire may not take solder and may need to be completely replaced.\n\n\n\nIf you are uncomfortable, go to your local hobby shop and ask for assistance. They are usually helpful, either by doing it for you or showing you a safe way to do it yourself.\n\n\n\nPoor Connections In The Servos\n\n\n\nThe servos are the hubs of activity in your car. They receive the orders to carry out an action. Sometimes the information isn\u2019t fully processed due to poor connections. Most of the time, this will result in inaction, as opposed to your car going by itself. However, on the rare occasion, it may just roll a little.\n\n\n\nSimilar to the advice on fixing the wires, only attempt to fix your own car\u2019s servos if you are comfortable doing so. Otherwise, a trip to the local hobby shop might be your best option to repair the issue.\n\n\n\nIs It A Ghost? \n\n\n\nThis is probably the first question that comes to mind when your RC car moves by itself but rarely is that the case (yes I said rarely, I don't want to make some ghost lovers mad). \n\n\n\nCheck out this video below of someone who is having this issue with their car. \n\n\n\n\nhttps:\/\/www.youtube.com\/watch?v=2G8bA2E7ZMU\n\n\n\n\nTo Wrap Up\n\n\n\nNothing ruins the fun of playing with your favorite remote control car than when it fails to do what you tell it to. Whether someone is messing with your car from a distance, you\u2019re in an area with increased interference, or there is something going wrong in your transmitter or car\u2019s inner workings, there are ways to troubleshoot and fix the issue.\n\n\n\nWhen changing up your frequency or channel doesn\u2019t work, you may need a change of location. Look around for steel structures, radio towers, or high power electrical lines. Try to steer clear of them. If you suspect someone is purposely messing with your car, a change of location is your best chance.\n\n\n\nYou may also need to do a little reconstructive work. As a seasoned hobbyist RC driver, you might already know the best way to work on your car. However, if you are new or dealing with a less expensive toy model, a trip to a hobby shop will help you.
