Remote Control Car Setup Tips

Posted on March 12, 2023 by blogger

Setting up a remote control car is as much a science as it is an art, the physics behind rc cars is exactly the same as the physics that governs real cars, if you know how setup changes in a race car work, you already know how to setup a remote control car.

The problem that most people have with setting up RC cars is that when you make a change in one area it always has a knock-on effect on the rest of your settings, setups are very much a balancing act

To start with I’ll concentrate on the basics of handling, over steer and under steer. The physics behind this is pretty simple, if you turn into a corner the center of gravity will move in what ever direction you were initially travelling. Your tires via friction push back with (hopefully) an equal amount of force. When your wheels lose traction and start to slide the energy that was being turned into heat in your tires gets released as inertial energy in the original direction of travel. With cars, both back and front don’t break traction equally, this creates either under steer or over steer, which is how we describe the experience the driver has under these conditions.

Under steer

Under steer is when the front of the car loses traction while the rear of the car still has grip on the tar, the effect is that the nose of the car drifts away from the direction you are turning, turning harder makes it worse, the only thing you can really do is back off the throttle and bleed off speed.

Over Steer

Over steer is the opposite of under steer, and in most cases it’s best to have a little of this. The front of the car keeps traction while the rear lets go. One of the key benefits is that you can typically corner much faster in a car that has some over steer

Over steer / Under steer Tuning tips

There are a lot of ways to tune the handling or your radio controlled car, the easiest is to adjust the front and rear shocks. While there are a lot of options with springs, different oils and all sorts we are just going to concentrate on the basics, most decent shocks have adjustments, either with spacers or bolts that let you adjust how hard or soft the shocks are.

As far as maximum and minimum stiffness goes, make sure that the bottom of your car doesn’t scrape the ground, and on the other end make sure it doesn’t bounce and leave the asphalt, apart from that you need to find the setup that matches your driving style, most people get winning setups off the internet and try to learn to drive them, mind you this is a great starting point, and most championship winners post their setup sheets

Shock Stiffness guide

Stiffen in front = increasing under steer or reducing over steer
Stiffen in rear = increasing over steer or reducing under steer

You may be wondering why one setting makes two changes, this is because it’s all about balance, you could for example setup your rc car by only every changing the rear stiffness, but you would find that when you got the perfect amount of over steer under braking the car would then be uncontrollable during the exit of the corner. It’s all about balance,

Another thing to keep in mind is that when you change the shocks you also change the roll of the car, this the the chassis of the car moving with the inertia, in effect pushing the front tires into the road during breaking and the rear during acceleration. If your shocks are too soft then the transfer might dig your front wheels in and lift the rear enough to make you car spin out, or lose steering under throttle, you have to find the right balance

Modern Car Care Myths

Posted on March 1, 2023 by blogger

Our vehicles can be costly, and for that reason, we all want to take good care of them and make sure we can get as much life out of them as possible. In this, most of us want to know what we should do to help our vehicles along but we also want to know what not to do, so that we arent wasting our money.

So what are some of the basic car care myths professionals have identified?

1. Myth #1 Tune-ups How often should you have your vehicle tuned up? Do you know? Most engines are computer monitored and controlled the good news with this is, they dont need tune-ups as often as a traditional engine. There was a time that with a standard tune-up, it often called for new ignition parts such as a distributor cap, spark plugs, and points and rotors. Besides spark plugs, which usually don’t have to be changed until 100,000 miles, today’s cars aren’t built with points and rotors, and many engines don’t have distributor caps that need replacement as often.

2. Myth #2 Having Your Car Lubricated In the old days, cars had chassis that needed lubrication. All that metal, potential rust you name it, the car needed to be greased. But now, cars are a combination of metal and plastic and therefore need little additional lubrication.

3. Myth #3 Flushing Your Radiator Annually – Manufacturers have made significant advancements in engine cooling systems during the past few years with closed systems that recirculate coolant. These new systems don’t lose coolant as often, and coolant manufacturers have also made advancements in their products’ chemical components with synthetic materials, making the seasonal radiator flush almost extinct. It is still important to check fluid levels periodically–especially before long trips–and use the manufacturer-recommended coolant. You should change your coolant about every four years. Coolant chemicals last longer than they used to, and newer engines aren’t going to be damaged by leaving it in long.

When changing your coolant, try a premixed formulation rather than adding tap water, which contains minerals that can cause trouble.

Some coolants will need to be mixed with water, in this case use only distilled water which doesnt have the hard minerals in it.

For those who live in extreme climates, hot or cold, then you should be paying much more attention to your coolant than others.

4. Myth #4 – Wheel Alignment We all want to keep our car in balance and were taught growing up to make sure our vehicle had the tires rotated frequently so that it stayed in alignment. Although it’s important to keep tires properly maintained and inflated, it’s not always necessary to have them aligned every time they are rotated. A majority of manufacturers recommend a wheel alignment and wheel balance only if there is a major issue with the car pulling to one side or another.

5. Myth #5: Winterize Your Car Many grew up with the notion that before winter came, you had to winterize your car. Your cars maintenance doesn’t have to be tied to the seasons. Todays modern cars dont require the same amount of attention. Professionals say, other than possibly changing to winter tires, modern cars don’t require special attention at this time of year the way that your parents’ car might have.

What can you do for your car before winter? During colder months, it is advisable for you to keep more gas in your car’s tank. Why this is due to the fact air carries moisture and water, which can freeze and crystallize. The more gas in the tank, the less air – and less chance of ice forming inside where it could get into fuel lines and cause trouble, he says.

So, dont spend unnecessarily, in these times, we all want to be a bit wiser about where our dollar goes. And enjoy your car for as long as you have it.
