How to maintain a healthy rc car

LiPo batteries are generally safer and more environmentally friendly than other R/C batteries like NiCd and NiMH. LiPo batteries have become the most common high performance R/C battery and are used in R/C cars, boats, planes, helis, multirotors and more. However, if charged, discharged, stored, maintained, or handled improperly, they can become extremely dangerous. This is a simple guide for safe LiPo battery ownership and use.

This guide applies to all R/C LiPo batteries including all the “smart” batteries made by DJI, like the Smart Batteries designed for Phantom drones, the Intelligent Flight Battery for the teeny Mavic Mini drones and the Intelligent Flight Batteries made for DJI’s racing drone, DJI FPV.

How to maintain a healthy rc car

1. Never charge, discharge, use, or store a damaged or puffy LiPo battery. Immediately follow proper disposal protocols.

2. Avoid purchasing used LiPo batteries. While some items are smarter to buy used to save money and help the environment, LiPo batteries are not one of those things. You never know what the previous owner did with them and they could already be badly damaged. “LiPo Battery Like New, Used Once” is usually a scam and should be avoided.

3. Always use a proper LiPo battery balance charger/discharger when charging and discharging your LiPos. It is crucial that all cells in a LiPo battery maintain the same voltage across all cells at all times. If the voltages across the cells deviate too much from each other (5mV

10Mv), the battery can become unstable and dangerous. (Unless it’s a single cell LiPo, in which case you do not need to worry about cell balance).

4. Always use a fire proof LiPo safety bag, metal ammo box, or other fire proof container when you are charging, discharging, or storing your LiPo batteries. While LiPo fires are rare, they can happen incredibly quickly and can do a lot of damage. All it takes is an internal short circuit to set the battery off. There is no way to predict when it will happen. It does tend to happen more often when batteries are fully charged, being overcharged, or while being discharged, but it can happen to any LiPo at any time. Never fill the container to capacity with your batteries, always follow manufacturer recommendations on LiPo bags for how many mAh’s it can safely contain. It’s ALWAYS worth investing in an (under $10) explosion-proof LiPo bag or ammo can.

5. Do not use your flight case/travel case for long term LiPo storage. The foam and plastic in these cases can help spread a LiPo fire. Always use a fire proof container such as a metal ammo box or fire proof safe for storage.

6. Never leave your LiPo batteries charging while unattended. If a battery starts to become puffy, smoke, or catches fire you need to be able to immediately handle the situation. Walking away for even just 5 minutes can spell disaster.

7. A LiPo fire is a chemical fire. Always keep a Class D fire extinguisher nearby your battery charging/discharging and storage area. The battery charging/discharging and storage area should be free from any materials which can catch fire such as wood tables, carpet, or gasoline containers. The ideal surface for charging and storing LiPo batteries is concrete or ceramic.

8. Never overcharge a LiPo battery. Typically a full charge is 4.2v per cell. Never “trickle” charge a LiPo battery.

9. Never discharge a LiPo battery below 3.0v per cell. Ideally you never want to go below 3.2v per cell to maintain a healthy battery. 2.9v per cell and lower is causing permanent damage.

10. Never leave your LiPo batteries sitting around on a full charge for more than 2-3 days. If by the 3rd day you realize you are not going to use your battery today, you need to discharge your battery down to 3.6v-3.8v per cell for safe storage until you are ready to use the battery again.

11. Care for your LiPo batteries properly. Always store your LiPo batteries at room temperature. Do not store them in a hot garage, or in a cold refrigerator. Even though a cold battery has less chemical reaction taking place which can prolong its lifespan, taking a battery out from a cold fridge can cause condensation to occur on the inside of the battery, which can be very dangerous.

12. Always remember that heat is the number one enemy of LiPo batteries. The hotter your batteries get, the shorter their lifespan will be. Never charge a battery that is still warm from usage, and never use a battery that is still warm from charging.

13. Depending on how they are used, most LiPo batteries typically do not last longer than 300 charge cycles. Leaving them around on a full or depleted charge all the time, running them completely dead, or exposing them to high temperatures will shorten this lifespan dramatically.

14. LiPo batteries do not work well in cold weather. The colder it is, the shorter your run times will be due to the slowing down of the chemical activity within the battery. If it is below 14F (-10C), LiPo usage is not recommended at all. Your battery could cause your R/C vehicle to suddenly fail without warning in these temperatures.

15. Always pack your LiPo batteries in your carry-on bag and never in your checked baggage when traveling on an airplane. It’s the law.

Rigidity, sensory sensitivities, coordination difficulties, and sleep dysfunction often go together with an autism diagnosis. These symptoms present their own challenges, but can also put a child at risk for being overweight or obese and for developing diabetes or heart disease as an adult. Although eating a balanced diet, getting enough exercise, and good sleep habits can be harder for children on the autism spectrum, there are strategies parents can use to help establish good habits that can last a lifetime.

Picky eating to avoid certain tastes or textures is common in children on the autism spectrum. This “food selectivity” can lead to a diet of sameness without a wide range of foods. It may be preventing your child from getting the nutrients he or she needs and may be contributing to a diet too high in fat and cholesterol. To help broaden your child’s food choices and promote a balanced diet, it is important to understand what your child likes or doesn’t like about certain foods. For example, if your child really likes flaming hot cheese puff chips, consider trying new foods that also have a spicy flavor or foods that are crunchy. Start from what you know your child likes and choose new foods that are similar but push the envelope just a little bit. If your child will only eat a certain type and brand of pizza (e.g., cheese pizza from Sally Smith Brand), try a different type from that same brand (e.g., pepperoni cheese pizza from Sally Smith Brand) or that same type from a different brand (e.g., cheese pizza from Troy Thompson Brand). Remember you can modify foods to change the texture, taste or other features (e.g., adding more or less peanut butter vs jelly in a sandwich, mixing something up to make it smoother, heating something up to make it softer).

Offer as many choices as possible when encouraging your child to try a new food, and allow them to be a part of the food shopping and food preparation process. The more control they have over the process the more likely they will be to be willing to try something new. And, each time they help you put something new in the shopping cart or help you prepare it, they’re getting exposure to that new food and learning to tolerate having it around them. And finally, remember that research shows that children need up to 12 or 14 exposures to a new food before they begin accepting it into the food repertoire. So if they reject a food after a first taste, praise them for trying and let them know it might taste different next time. And then keep presenting it!

Getting enough exercise is another challenge for some individuals on the autism spectrum, who tend to be more sedentary than their typical peers. Trouble with coordination and motor skills can be one reason. Also, children on the spectrum may dislike playing some sports due to the fast pace, lack of predictability, and/or social and communication demands (both verbal and non-verbal). Finding an activity that your child enjoys and that can be incorporated into his or her regular routine is critical to helping your child stay active. Whether it is jumping on a trampoline, swimming, or a team sport, exercise by whatever means can help individual on the autism spectrum maintain a healthy weight. Exercise also has the benefit of improving mental health and attention.

Sleep is also an important part of overall health. In addition to affecting daytime behaviors and mood, poor sleep is a common risk factor for obesity. Children on the autism spectrum are more likely to have problems sleeping or staying asleep. Not sleeping well and waking up often during the night prevents individuals from getting enough of the quality sleep all bodies need. To ease bedtime stress, try to follow the same calming nighttime routine. Make sure that the room is dark and comfortable. Limit screen time at night. Outside play time during the day can also help your child fall asleep faster.

Parents may feel stuck when trying to find the right healthy routine for their child. A child on the autism spectrum may not be motivated by health benefits or social acceptance in order to maintain a healthy weight. Occupational therapists are great resources for weight management ideas. They can help parents introduce new foods and find ways to fit physical activity into your family’s routine. Programs like CHOP’s Healthy Weight Program can also help make a plan that fits your family.

Here’s how to maintain the health of your car battery and how to jump-start it when it ails.

Following the proper steps of jumpstarting your car keeps the battery – and you – safe.

Today’s batteries can last for years with very little maintenance. But age, damage, or inadequate charging can make even the best battery too weak to start your car. Some simple preventive measures will go a long way toward keeping a battery healthy. And when it falters, a jump-start is sometimes all you need to be on your way.


The main safety concerns with batteries are the possibilities of severe shock and of explosion, with a consequent spray of sulfuric acid and battery shards.

A battery creates hydrogen gas, which is explosive and can be ignited by a spark. Even if it’s too weak to start your car, a battery still may be able to give you a considerable shock. So don’t smoke or wear metal jewelry near it. Do wear eye protection—safety glasses or goggles.


Keep the cable connections clean and tight. If the battery has caps that let you check the water level, keep it up to the full-mark (usually just under an inch from the top of the cell). The battery should be tightly clamped so it can’t slide.

A mechanic can run a diagnostic test on your battery to check its health.


If the battery is sound but too weak to start your car, the alternator will probably be able to recharge it as you drive. The trick is to get the car going, and jump-starting will often do the job. But before you get out the cables, check your vehicle’s owner’s manual. Some carmakers advise against jump-starting to protect the car’s electronics from a power surge.

In addition, some batteries have a “state of charge” indicator. A fully charged battery has a colored indicator, usually green or red. Black or clear means the battery is completely discharged and you should not try to recharge or jump-start it. Also, never try a jump-start if the battery’s frozen.

You jump-start a car by attaching the weak battery to a similar but strong battery with cables specially made for the job. It’s important to follow the exact order of procedure to do this safely:

Locate the battery. It has two terminals, each marked with a symbol: – for the negative and + for the positive. In some cars, the battery is difficult to reach, so there is often a more accessible remote positive terminal in the engine compartment.

If you can’t access the terminals—or even find the battery—consult the owner’s manual.

The good battery must be similar to the one in the car that won’t start. Most gasoline-powered cars have 12-volt systems; older cars may have six-volt systems. Park the car with the good battery close enough for the cables to reach the car needing a start, but not so close that they touch.

Turn off the ignition and all accessories on both cars; set parking brakes; put transmissions in park (automatic) or neutral (manual).

Connect the cables in this order:

—Connect one cable to the positive terminal of the weak battery.

—Connect that cable’s other end to the positive terminal of the good battery.

—Connect another cable to the negative terminal of the good battery.

—Connect the other end of that cable to a ground on the car that won’t start. Check the owner’s manual to see if there’s a special ground terminal under the hood. Otherwise, the engine block is a good ground. Do not attach the cable to the negative terminal of the faulty battery.

Start the engine of the car with the good battery and let it idle.

Start the car with the bad battery.

After you get the jumped car going, disconnect the negative cable from its ground connection, then from the terminal on the good battery. Next, disconnect the positive cable from both batteries. If the charging system warning lamp stays lit and the engine dies, another jump-start won’t help. If the light goes out, there’s a good chance the battery will recharge as you drive.

If your battery fails, AAA Battery Service can bring a replacement to you, install it, provide a warranty, and dispose of the old battery—all at member prices (cost varies by make of vehicle). Battery Service also can help you determine whether you actually need a replacement by diagnosing the condition of your current battery.

Test your ride’s power supply and replace the battery on the spot.

    How to maintain a healthy rc car

    Growing your beard is one thing. Any guy (well, most guys) can do that. But it takes consistent, proper care to keep your beard healthy, manageable, and looking its best.

    Beard care is important – but it doesn’t have to be complicated. We’ll make it easy for you by drilling down to just 5 key steps you need to maintain an enviable beard.

    Follow these beard maintenance tips and you’ll have a healthy, awesome looking beard for life (or however long you decide to keep it).

    Let’s be honest – your beard can get pretty gross if you don’t make a concerted effort to keep that thing clean. Crumbs and other leftovers of the day can get stuck in there, especially if you’ve got a long, thick beard. Beards are great, but if you don’t wash yours 2-3 times each week, you’re not doing yourself any favors.

    You’ll find beard specific cleansing products from some brands, but the truth is your shampoo will do just fine. Our Daily Strengthening Shampoo uses gentle cleansers, contains zero sulphates or phthalates, and will keep your beard clean and smelling great. It will also prevent any gross buildup (caused by sweat, excess oil, and other debris) from accumulating in your beard.

    How to maintain a healthy rc car

    To keep your beard soft and shiny, condition it regularly with beard oil. This also moisturizes the skin underneath your beard to prevent itchiness, control flakes, and maintain follicle health. Remember, your beard is only going to be as healthy as the skin underneath it.

    Never used beard oil before? No worries – it’s easy:

    1. Pour a few drops (less is more) into the palm of your hand and spread it evenly between both hands.

    2. Massage the oil into the base of your beard (it can be dry or damp for this step, but should not be wet).

    3. Work your hands through your beard until you’ve reached the hair tips. Spread the oil evenly over your entire beard and the underlying skin.

    How often should you apply beard oil?

    • If you live in a dry climate or have dry skin/hair, apply it daily or every other day.
    • If you have oily skin/hair or live in a humid climate, apply it 2-3 times per week.
    • If you notice oily buildup or your beard gets greasy, apply less often.

    How to maintain a healthy rc car

    Trimming is essential to keeping your beard looking well kept and healthy. You can use scissors for a more precise trim that is less likely to damage your facial hair. Beard trimmers are easy to use and make the process quick with their measured length guards, but they can also cause split ends and may damage your hair. Using beard oil will help reduce split ends.

    How often should you trim your beard?

    Every few weeks, grab a pair of scissors or beard trimmer and take a close look at your beard in the mirror. Are there uneven patches, long spots, or split ends? If so, even things out and remove the damaged hair.

    How to maintain a healthy rc car

    As you’re trimming your beard, make sure you’re following the natural contour of your face. Keep a rounded shape with all the hairs at a uniform length for the best look. In general, less is more when it comes to trimming. If you get too overzealous with your trimming you might end up having to take the length down everywhere just to maintain a balanced look. Easy does it.

    Even when you’re still growing out your beard, a slight trim from time to time is a smart idea. That will keep your beard under control and not turn the growing-out process into “that few months where I hate every picture of myself”.

    Out of control facial hair is never good, whether you’re growing it out or not. So use these tips to trim up those rebellious whiskers on your way to a stellar beard.

    Worried about over trimming or ending up with uneven beard length?

    You can avoid this by brushing your beard with a small comb as you trim. That will show you which hairs are loose, which are uniform, and which still need to be trimmed. Comb down your beard after each cut so you can see the length and trim in the all the right spots without overdoing it.

    Give your mustache extra attention.

    Your mustache may be a minor part of your overall beard, but it’s a major part of how good your beard looks. Nail the trim of your mustache and you’ll always look great. Get it wrong and it will throw off your facial expressions and give you an unbalanced, unflattering look.

    Give your mustache a little extra TLC. Invest in facial hair scissors that give you a natural result each time you trim up the ‘stache. A small comb is another critical tool. Use it to brush all your mustache hairs straight down to properly assess its length and bulk.

    Should you trim/pluck gray hairs?

    Yes, you’re getting older. Yes, your beard may be getting a bit more salt and pepper than you like. But no, the answer is not plucking out individual gray hairs. Many experts say that plucking out grays will only make more come back. But it’s a fool’s errand – you can’t stop the aging process. Embrace the salt and pepper beard – it’s masculine, distinguished, and attractive. Using our science-backed anti-aging products is a much smarter way to fight the aging process while looking your best.

    Your trimmer is an essential tool for cleaning up your neck line. For most guys doing this every two weeks is plenty. Here’s how to do it:

    • Stack your index and middle fingers just above your Adam’s apple.
    • Trim your beard to where your top finger is.
    • Trim a U-shape from your side burns down to meet this point.
    • Do not just follow your jaw line. That will result in an awkwardly shaped beard.

    Your mirror is your friend when learning to trim your neckline. It can be scary – you don’t want to go too far and mess up your beard. So take it slow and easy, especially when you’re first gaining experience with your trimmer.

    Your beard is an outer reflection of your inner health. If you want a thick, healthy beard, make it a part of your overall healthy lifestyle. That includes getting enough rest each night, making exercise part of your routine, and eating a balanced diet.

    Health living promotes good hair growth, keeps your hair strong, and and keeps you looking great. So be proud of the lifestyle choices you make and enjoy how awesome it makes your beard look.

    How to maintain a healthy rc car

    A new engine costs more than a used car in most cases, so taking care of it is critical, especially in the fragile and uncertain economic climate we’re experiencing.

    Most damage is done in winter, when owners tend to make a very common mistake: they start the car and leave it idling until the engine reaches the normal operating temperature.

    If the car does not feature auxiliary heating, this can do more harm than good because the engine warms up at a much slower pace when idling.

    Oil flow and temperatures also rise slower and the increased amount of exhaust gasses can clog the catalytic converter, causing an increase in fuel consumption and emissions or can lead to it failing.

    The best way to avoid this is to leave the car idle for a couple of minutes then drive off slowly and maintain normal revs until the engine reaches optimum temperature. This will happen a lot faster and exhaust gasses will be properly eliminated.

    How to maintain a healthy rc car

    Once you get moving, regardless of the season or temperature, it’s important to keep your inner Lewis Hamilton at bay, as much as possible.

    Driving aggressively and at high speeds frequently does not only get you in trouble with the law but also increases the wear of the engine, especially if you’re not driving a high-performance car.

    If you’re driving a manual and get overtaken by an uglier, older, and less capable car, flooring the accelerator at low revs or when in a high gear is a bad idea as well.

    This will make the engine work hard unnecessarily and cause premature wear, so keep an eye on the tachometer (rev counter) and downshift before you floor it.

    How to maintain a healthy rc car

    Another tip for manual gearbox enthusiasts is to avoid excessive engine braking. This eventually damages the powertrain and should be used only in extreme cases like winter driving, when the road is icy and slippery.

    SUVs and trucks are popular because they are designed from the get-go to offer handle bigger loads and better towing but a normal car with a small engine is not. That’s why it is important to avoid big loads if your car was not built for this. Like the other bad habits we discussed, it will put a strain on the engine and cause excessive wear.

    Finally, if you recently bought a new car keep in mind that its engine requires a break-in period to help all the moving parts adjust and settle. The temptation to push a new car hard from the get-go is hard to resist, especially if it’s a capable performance vehicle.

    But driving it at normal revs and legal speeds for the first 700 miles (1,127 kilometers) or so could make a huge difference in the future. Pay close attention to the information provided by the dealership and consult the owner’s manual for the best way to break in and protect your new engine.

    Until fully autonomous driving and electric combustion will take over and completely replace vehicles as we know them, changing out bad driving habits and prolonging the life of our beloved ICEs should be a priority for anyone who loves their cars.

    Part three of a series where health professionals share their tips for a healthy lifestyle

    1. Nicola Sheridan

    Clinical specialist physiotherapist, Children’s Hospital Ireland at Temple Street
    “Children need a combination of aerobic and strengthening exercise to develop fitness and skills of balance, co-ordination and visual motor control. Children need at least one hour of exercise daily and limiting their screen time can help them achieve this. Having fun when playing also improves mood, confidence and self-esteem.

    “Ideally, children should not become sport specific too early, to allow their muscles, joints and skills to develop across a range of activities. They need to explore and ‘free play’ with other children to develop a range of skills in a fun way, at their own pace.

    “For strong bones and leg muscles, children need weight-bearing exercise. Bones get stronger during any activity that involves running, jumping, hopping, skipping, dancing, or a combination of these. For strong arms and posture, children need activities that challenge their postural control and balance – like climbing, yoga, dancing, gymnastics, horse or bike riding, martial arts and playground play.

    “From age nine onwards, when sport becomes more competitive and growth spurts are also happening, regular stretching and rest days from structured sport are important to prevent inflammation at bony growth points. Broad experiences across a variety of games and activities develop flexibility and ligament control which, in turn, prevents injuries. Good co-ordination and balance prevents trips and falls, and thus childhood fractures.”

    2. Vanda Cummins

    HSE primary care physiotherapist
    “Exercises that keep us strong, steady, straight and ‘switched on’ aerobically are the most effective. We start losing muscle and bone strength every year after the age of 30. Ill health, pregnancy and menopause accelerate this loss. It’s far more serious than most people realise so action is needed.

    “Emerging research shows muscles and bones can strengthen with resistance and impact exercises. Resistance exercises such as pushing, pulling or lifting a load make muscles work harder than they’re used to. Exercises with impact, include marching, jogging and dancing are good and should be increased over time to 30-50 repetitions.

    “There are exercises to benefit all abilities and if you are living with conditions like arthritis or osteoporosis, physiotherapists can teach you how to exercise safely instead of not doing exercises. Regular progress checks can keep you motivated and may include you monitoring the number of times you can stand up in 30 seconds without using your hands or how many seconds you can stand on one leg [beside a support].

    • Five experts, five tips: Heart experts on good heart health

    “While there’s no quick fix, or one exercise to suit all, start small, build slowly and ‘train to gain’. Make exercise a habit for life just like brushing your teeth.”

    3. Victor Megannety

    Osteopath in Greystones, Co Wicklow
    “If you look after your structure [ie, your musculoskeletal system], your body will function better. If sitting or even standing for long periods, take a postural break every half-hour, or at least every hour. To do this, stand up. Open your arms, palms facing upward and bend your whole body backwards. Hold for at least 20 seconds. Doing this regularly throughout your day is more beneficial than one long period of exercise.

    “Regular gentle exercise is important. Walk at a good pace – slightly out of breath but still able to talk, and creating a slight sweat. Ensure the ergonomics at your workstation are correct. Laptops are lethal. Invest in a stand or separate desk screen. Or at least put your laptop up on something so you’re not looking down at it.

    “Listen to your pain. Pain is like the warning light coming on in your car. Simply taking painkillers or ignoring it is like putting a plaster over the warning light. Pretty soon your body – like your car – will break down. Of course, the musculoskeletal system doesn’t work alone and your diet, hydration, sleep, stress control and emotional wellbeing all contribute to keeping you well.”

    4. Richard Brennan

    Alexander technique teacher
    “Most of us are not aware of the muscular tension we hold as it builds slowly up over many years affecting our posture, our movements as well as our mental and emotional wellbeing. To release this tension you can try this Alexander technique awareness 15-minute exercise:

    “Lie down on a carpeted floor with the support of some books or a pillow under your head. Bend your knees so that your feet are on the ground and knees are pointing upwards. Since muscular tension always shortens or narrows the body you can send instructions to your body to lengthen or widen. Alexander called them ‘directions’. It is important that you think only of these directions and do not do anything. Some examples are: ‘Think of your back lengthening as it makes more contact with the floor,’ or ‘Allow your shoulders to move away from each other and away from the head.’

    “Any direction that allows one part of your body to move away from another part will help to release this detrimental tension. You may or may not feel the tension release at the time, but with daily practice over a few weeks you should feel more relaxed, less discomfort and more energy.”

    5. Neil Fleming

    Exercise physiologist at the Human Performance Lab at the School of Medicine, Trinity College, Dublin
    “Slow down and listen to your body. Most people train at too high an intensity and end up injured or over-trained. Use the talk test to control intensity. You should be able to hold a conversation with your training partner or sing a line or two of each song you’re listening to without getting breathless. Better yet, use a heart rate monitor. For most of your training, your heart rate should be no higher than 85 per cent of your theoretical max (maximum heart rate equals 220 minus your age). More minutes at controlled low intensity is the key to success.

    “Take time to prepare. Devote a minimum 10 minutes to a warm-up routine before every session. This should include five minutes of moderate intensity cardiovascular exercise, followed by another five minutes of dynamic stretching exercises where you move your muscles and joints through their full range of motion. This reduces risk of injury and enhances your performance during training.

    “Taking the time to cool down with static stretching at the end will enhance the recovery process, reduce any muscular pain or tightness, and keep your body in good condition long term.”

    Five experts, five tips

    When you first got started, you used to be so excited to spend time with your Traxxas hobby car and raced around for hours. The jumps, the turns, the spins, or just driving around in circles. It didn’t matter, as long as your car did whatever you told it to do.

    But now something’s off, and you don’t know how to fix it. UGH! What a tease!

    Faulty RC car steering can ruin your entire hobby experience. Honestly, what’s the point of a remote control car that won’t respond to your remote properly?

    Don’t worry, we got you. We’ve compiled a list of the most common RC car steering problems and how to fix them.

    But first, a little background on how your steering really works (aka, a lesson on RC cars for beginners).

    All Roads Lead to The Servo

    99% of the time, your car is only as good as its relationship with the servo– short for servomechanism.

    Every RC device needs a servo to convert radio signals into movement. Every helicopter, boat, train, off-road jeep or slick pavement car has a servo somewhere in the body. For RC car kits specifically, your servo dictates how fast your car can go and dictates almost everything about the steering quality.

    Before you do anything else, check the following in your Traxxas race car:

    1) You Have the Right Servo and Servo Horn

    Whether you constructed your car yourself from a kit or bought it ready to run, you need to make sure the servo horn is set on the chassis properly. This horn is the main arm of your servo, or the conductor’s wand if you will.

    Double and triple the instruction manual. Some models need the servo horn to be off-kilter on the chassis, or at a slight angle. The car won’t function properly if the servo horn is installed perpendicularly. On the other hand, other models need the servo horn to be at a perfect 90-degree angle on the chassis.

    You might also be using the wrong size and strength servo for the way you’re using your car. If you think you may need to replace your servo, finding replacement carts by model and installing them yourself is pretty simple.

    2) All Your Links are the Right Length

    There are sets of links in every car kit that connect the servo to the steering rack and the steering rack to the wheels. Even if your radio and servo are communicating properly, your car won’t get anywhere if the links are the wrong length or installed poorly.

    Once you’ve made sure your servo and servo horn are functioning, check your links. Make sure nothing’s obstructing motion from the servo to the steering rack to the tires. They should all respond smoothly and instantly.

    3) Your End Point Adjustment is Set Correctly

    Setting your radio’s end point adjustment (EPA) helps your servo and steering rack understand the finer motions of your steering.

    Before setting the EPA, your car needs to be on the ground at drive height. Make sure the wheels fully lock to the left and the right when setting endpoints. You may need to press your car into its shock mounts a few times to be sure it’s at true driving height.

    4) Your Radio and Servo Have a Good Connection

    It’s pretty obvious when your radio won’t turn on. Sometimes your servo’s transmitter will stop receiving anything from the radio even if the radio and rest of the servo are functioning.

    An easy way to make sure the servo transmitter is working is to switch the servo and throttle connectors. If the controls on your radio then become switched, you know everything’s working correctly.

    Most steering problems will lead back to one or more aspects of this basic set up.

    Now, let’s break down and troubleshoot the most common RC steering problems we see talked about in hobby forums:

    Throttle Works, But No Steering

    Your car turns on and lights up appropriately, but the steering doesn’t work at all.

    Check to see if the.

    • servo gears are stripped
    • servo wires are frayed
    • servo connector is loose
    • the links are connected properly and responding to the servo

    Steering Sticks Left or Right

    Your car can turn both left and right but tends to lean one direction much more than the other. Or, it has no problem turning but struggles to stay straight or keep centered.

    This is most likely a problem with the servo horn or where the servo trim is centered. Check your servo horn and all links.

    Tires Automatically Turn Hard Left/Right

    Your car’s tires immediately turn hard to the left or right as soon as you turn the car on, or after using it for a few minutes.

    Again, check the servo horn and where the servo trim is set. Make sure the EPA is reset properly. If all that doesn’t work, there’s a chance some of the gears of your servo are stripped, or the links on one side of the car are loose.

    More About RC Car Steering

    See? There’s hope for you and your dysfunctional car! All is not lost.

    To recap, RC car steering problems can almost always be solved by troubleshooting these things first.

    The servo itself – Make sure you have the right size servo and that it’s installed properly. Make sure the gears and wires are in good condition and respond well to your radio.

    The servo horn and links – Make sure the servo horn is set on the chassis at the correct angle for your car make and model. Make sure all links are the right size and respond smoothly to directions from the servo.

    The EPA – You may need to reset your End Point Adjustment a few times and make sure the radio and servo are communicating well.
