RC cars are a lot of fun, but when they start going by themselves, it can be pretty frustrating. In this blog post, we will discuss the reasons why your RC car might be doing this, and how to troubleshoot each problem. We will also provide some tips on how to keep your vehicle on track!
Reasons Why Your RC Car Moves By Itself
One reason why your RC car might be going by itself is that the battery is low. If the battery is running low, it will not have enough power to keep the brakes on if your car has them. To troubleshoot this problem, first, check to see if the batteries are charged. If they are not, then charge them for a few hours before trying to use the car again. If the batteries are charged, then check to see if the battery connections are loose. If they are, then tighten them up and try using the car again.
Another reason why your RC car might be going by itself is because of a problem with the motor. If the motor is not working properly, it may be able to move the car forward without any input from the transmitter. To troubleshoot this problem, first, check to see if the motor is clean. If it is dirty, then clean it with a brush or an air compressor. If the motor is clean, then check to see if the brushes are worn out. If they are, then replace them with new ones.
If your RC car is still going by itself after you have checked the battery and the motor, then there might be a problem with the drivetrain. The drivetrain includes all of the parts that move the car forward, such as the wheels and axles. To troubleshoot this problem, first, check to see if any of the parts are loose. If they are, then tighten them up. If the problem is still not fixed, then you might need to replace some of the parts.
Another reason your RC car could be going by itself is that it is out of range. Make sure to check your transmitter’s range, this information should be available in the handbook. Also, make sure to check the antennae on the transmitter and the receiver, if either of these is broken then the range will be greatly reduced.
Finally, if your RC car is still going by itself, then there might be a problem with the transmitter. The transmitter is what you use to steer the car and make it accelerate, brake and reverse. To troubleshoot this problem, first, check to see if the batteries are charged. If they are not, then charge them for a few hours before trying to use the car again. If the batteries are charged, then check to see if the connections are loose. If they are, then tighten them up and try using the car again.
Make sure to also check the trim controller on the transmitter, it will be a little lever that you move up and down in increments. This is usually found next to the throttle control.
Check The RC Car’s Tuning Setup
If you have a gas or nitro RC car you should check your idle screw which can be found on the engine block right next to the carburettor. If this is not set correctly you could be providing too much fuel mixture to the car whilst it is idle. This will result in the RC car moving by itself.
How Can I Improve My RC Cars Handling?
If you want to improve your RC car’s handling, then there are a few things that you can do. First, you can adjust the suspension. The suspension is what absorbs the shocks from the bumps and jumps that your car will encounter while driving. To adjust the suspension, first, find the screws that hold the shocks in place. Next, use a screwdriver to turn the screws clockwise or counterclockwise until you find the setting that you like.
Another thing that you can do to improve your RC car’s handling is to adjust the tires. The tires are what provide traction between the car and the ground. Make sure you have the correct tyre pressures and that there is plenty of tread. The grip can make a world of difference when it comes to handling.
What Will Happen If My RC Car Goes Out Of Range
If your RC car goes out of range, then the most likely scenario is that it will keep going in a straight line until it eventually runs out of battery power and stops. This could be a problem if your car is close to a road or edge as it could cause an accident. To avoid this, make sure to check your transmitter’s range before using it and keep an eye on your car at all times. If you think it is going out of range, then steer it in a different direction to be safe.
Final Thoughts
An RC car going by itself is quite rare but does happen, we hope that by following our troubleshooting guide you will find the reason why your RC car is going by itself. Hopefully, you will be able to rectify the problem fast and get back to enjoying this awesome hobby.
I am a massive fan of anything that is remote controlled. This stems from my childhood when my Grandfather would take me to a local RC flying club and I would dream about having my own RC models someday.
