It becomes highly addictive. Every time i go out, somebody asked me: how fast does that go mister that’s what everyone wants to know, and it bills and bills and bills. We want to inspire those people that watch as your car blasts down the street past them going like a bat out of hell. Everybody wants to be a person like that that’s driving a super fast car. So how do you make your rc go faster? Well in this guide, hopefully you will be pleasantly surprised as to just how easy it is, and in some cases, just how cheap it is to make your rc car go much faster, so let’s get started, and hopefully this guide is going to send you down the Right path to get any extra speed well, first of all, let’s start off with the basics and by the basics i mean gearing simply by changing the gearing on your car, you can dramatically improve or decrease the top speed of your car. Gearing is the absolute starting point of any quest for more speed or more acceleration, but when it comes to gearing choice, that’s going to be down to your personal preference, where do you want the power? Do you want it at the bottom end, so you can accelerate. Like hell and help drag race, your friends, do you want it at the top end, so you can pull away from them, leaving them in a trail of dust behind you, because the choice of the gear, pinion and spur dramatically affects where the power is delivered.
On your car, so on my guide to gaining more speed, your first decision is: where do you want to gain that more speed? Do you want it at the bottom end, so you can now accelerate your friend or do you want it at the top end? Because your choice of pinion and spur will dramatically affect that i’ll take these mod one gears out of the box to give you a demonstration on here: small pinion gear, big spur gear; okay, that is going to give great acceleration with that kind of ratio on here. It is going to go far faster at the top end if you’ve got this larger opinion and stick with the same spur gear on there, but but the car is going to accelerate much slower. So while she might be pulling away from your mate at the top end, he could well be pulling away from you in a drag race as an example. So you need to decide where you want the power, and this is often down to a lot of trialling and testing of the gear combinations on there. As you might gather, i’ve been through this process quite a bit. A lot of these ones are quite expensive. The metal mod one gears in particular you know it’s in the main i’ve got metal gears in here the plastic ones that a lot of varsity cars initially come with. I would say it’s one of the first upgrades you want to make, because if you make any driving mistakes, the metal gear train is far more forgiving, but some basic stuff.
Regarding gearing 101, a larger spur gear is going to decrease the top speed, a smaller spur gear or even very small spur gear is going to increase the top speed of the car. Likewise, dropping down in pinion size is going to increase the acceleration of the car, but keep the top speed low. You fit a big opinion it’s going to increase the top speed but decrease the acceleration of the car. So a lot of it is down to personal driving preference and a bit of experimentation, or in my case rather a lot. But then i’ve been at this for quite a while, and the one thing would say is if you want to keep your palmer in life. Happy lie about the amount that you spend on rc, because i’ve spent more on rc car gears than i could care to ever mention to my wife before we go on to talk about power plants, if top speed and performance are the goal of your rc car You’Ll want to take a good look at what battery pack. You are powering the car with. If you upgrade to a high performance battery pack, it is one of the best possible upgrades you can make to your car. A lot of people are afraid of this rating. On here, the c rating of the battery do not be afraid of that i’ll explain in a minute. That is not what kills esc’s literally. If you want to boost the performance pretty much any size, rc car vehicle, you can simply upgrade the performance by picking the same size battery pack, but with a higher discharge rating as an example.
If this one, if i had one here that was a 5 000 milliamp, 50 c 6s pack, this 100c 6s pack would give the car more top end. Every single time on there i’ll explain a little bit more about the c rating in a second, because it is important. A lot of people are afraid about the c rating don’t be afraid about the c rating. That is not what kills esc’s. What kills escs is too much current or too much voltage. Never the c rating. If you want the highest speed out of your rc car, go for the highest c rating. You possibly can, however, always refer to the speed controller specification as you don’t want to exceed the maximum amperage ratings or the maximum voltage. That is what kills esc’s, not the c rating. In fact, on some of the armor cars, it actually says to have a battery of a mid. It actually says to have a battery about like above 50c rating on there. Otherwise damage to the esc can occur by having too low a c rating. But just remember no one goes fast if their esc dies through the wrong battery. Now there is nothing wrong with still using nickel metal hydride batteries, and that, indeed, is where many of us start out, but one of the biggest advantages to using lipo batteries is the much larger amount of current. They supply particular peak rates of demand when you, when your motor is running flat out when you’ve got your throttle finger squeezed hard down.
These will deliver more power, more current, etc than the equivalent voltage nickel metal hydride battery will do and that peak boost in power output substantially helps the speed that your rc car is going to travel at one of the biggest things that i pay attention to when Buying any battery is what nearly marked with here is this rating 24.42? What hours the higher the? What hour that the battery gives the more power? The thing is going to give out simple, as that and the one advantage of lipo batteries is, you can get them in a huge range of different sizes to fit pretty much any vehicle that you want where nickel metal hydride cells tend to be in either seven Cell, like this, eight cell pack, six cell pack very limited because the size of the cells are physically the same when putting these packs together, as you can see on the lipo packs here, simple 2s, 2 000 milliamp battery 3s, 2, 200 million battery very different in Size but both equally potent the one thing is: if your car came with the nickel metal hydride pack ensure the esc is lipo capable because if not the thing is going to go south very fast indeed, and you do not want the esc burning up and potentially Shorting out the lipo, because if that happens, and the lipo goes into flames, you’re going to have to very fast indeed to recover your car a little bit more care required when handling lipos but that’s.
The stuff is a whole different video but fit the right lipo to your car, like this awesome, genzis, 3s, 15, 000 milliamp, 100c pack and it’s like adding nitrous oxide to your rc cars performance anyway. We’Ve got the gearing sorted the battery sorted. So what about that? Motor now it’s time to look at the big upgrade upgrading your motor. Quite possibly the most obvious option. Changing out the motor for a high performance model is one of the best ways to get a sizeable performance increase from your rc car they’re offered in all sorts of different sizes and specs from high torque slow crawler motors like this one from axial all the way To blazing fast speed demons like this ready, 19 turn motor with fully adjustable timing again brushed motor on there. This is just a few examples. Basically, whatever you need, there is going to be the ideal option for what you want to achieve now. Picking the speed of your brushed motor is made easy with the conventional turns rating system like on this 20 turn motor, which is the number of word, turns wrapped around each motor coil, the lower the number of turns the higher top speed the motor will spin as An example something like this rc 10 back in the day in a modified form, might use something like an 8 turn to a 5.5 turn motor, but in this case i’m fitting this 19 turn radio motor in there well on road road racers that may use motors.
As low as 4.5 turns any of which are going to make your rc car fly along now for the types of motor, we have a choice between brushed or brushless. All these brushed options, while still older, provide huge bang for your buck. They’Re still widely available and there’s. Still, some very high speed options out there and they’re generally in the 10 to 12 turn range, but you can get ones down at four and a half five turns which can output huge speed, so don’t completely rule them out, as you do have to bear in Mind if you change the brushless you’re, also going to have to swap out the esc, switch over to lipos and that’s, quite possibly going to mean buying a lipo battery charger as well, so there’s a little bit more expense involved in going brushless other than just the Simple upgrade of the motor itself, and i would just – and i would just say no, you cannot fit a brushless motor to a brushed esc, two wires, three wires, but if you’re looking for the best of the best in terms of performance, you really want to be Looking at brushless options, brushless motors can output a good deal of low end torque and some serious top speeds case in question here. This is a castle brushless motor 2280 kv. This is their crawler edition one. So you can fit this brushless motor to a crawler. It would have thought of that, but this thing generates huge torque gives you a huge amount of control, as it is censored capable on here so, but with brushless motors the kv, the higher the kb, the faster you go right, rich! Well, yes, and no! So, as you can see, brushless motors also come in a variety of specifications, with top speed usually being donated by the kv rating.
Typically, the kv rating is easy to follow. Higher numbers like this traxxas three and a half thousand kv motor will represent higher potential rpm or higher top speed under the upside fast brushes motors. Is they also tend to have a lot of low end torque that allows you to further tune your gearing for top speed? So you can still get good speed off the line, but a high potential top speed. However, don’t be afraid of going for a low kv motor, because this one will have probably a lot more torque, even though it’s lower kv than this one and this traxxas motor well, it will take 3s. This castle, one 2280 kv, will probably take 4s, so you can increase the number of revs on the thing. Yet it’s got more torque on there, so it’s a balanced snap in terms of the kb’s of the motor versus the torque of the motor and how high a gear you can turn in order to go faster. At this point you might gather there is going to be a bit of an issue between high kv and low kv motors. For one thing, a lower kv motor is more likely to like a higher lipo voltage, so this traxxas one is only good for 3s, but this castle one will probably take 4s and it will generate more torque, so you’ll be able to give this the speed up. So you’ll be able to get the motor up on here to increase the speed, so don’t think just by getting a higher kv motor it’s going to be any faster than the lower kv, one which you might be able to run on a bigger lipo battery.
I hope that makes sense, and one thing i mentioned earlier is the esc’s it’s, like the final part in the puzzle to going faster, you can have the best battery in the world. You can have the best motor in the world. You can have the best gearing setup in the world, but if the esc isn’t delivering the power the battery can to give the performance, the the motors certainly can give then you’re on are hiding to nothing on there. So in general, higher current esc’s, like 150 amp one, is going to be way better than something like a 90 amp one on here. However, to get the best and the top speed out of your car, it is better if you go for one that is fully programmable. That enables you to do also things like the timing and the boost of your brushless motor in order to maximize the peak speed of your car. Well, my final thoughts are reaching high speeds. Doesn’T have to always be complicated, hopefully by following the simple guide i’ve. Given you there taking a look at the available, gearing that you’ve got the available batteries on hand that you could have to order the available motor choice can mean that you can go from being the slowest car on the block to the fastest kid in your county. Anyway, i hope you found it richie’s easy guide to going faster, useful. If you did then don’t forget to like share and subscribe thanks for watching well thumbs up.
