Let’s take a look at how electric RC works. I will put it into a simple concept map to make it easy to understand, especially for RC Car. When you understand the basic of it, you might even be able to troubleshoot it if run into a problem. There are also many RC communities out there that will be happy to help you.
Here is how Electric RC car operate:
It is important to understand how it works before looking to upgrade parts for a better performance. Researching and planning out before buying it will help you save a lot of time and get the correct parts.
What to Consider before buy
Battery: It powers up your ESC. It is important to get a good battery, whether it is NiMH or LiPo for RC car. LiPo battery is popular and rate from 7.4v for 2 cell, 11.1V for 3 cell, etc. I usually use 7.4v 2s for my drift car since it gives enough power. If more than that, it would be overkill. LiPo battery usually uses with Brushless ESC and Motor.
Balance Charger: For charging your battery. Get a good balance charger will keep your battery last longer. The price is around $25-$60. Some charger will let you charge many different types of batteries and might come with more than one charger plug. If you using LiPo battery, the balance charger is a must. You should also use LiPo Safety Bag during charging or when done playing. The safety bag will keep the battery safe
ESC & Motor: These usually come together as a combo whether brushed or brushless. Unless you really want a specific spec, buy them as a combo isn’t a bad idea. Sometimes it is even cheaper. I like the combo that has Program Card included. This card will allow you to modify how ESC works like “go forward and brake” or “only go forward.” Some program card would also allow you to tune up power or speed setting. So read carefully if you try to buy without one. Brushless will give out much more power and heat. It will require you to use LiPo battery for maximum performance output.
Remote Controller and Receiver: Looks for 2.4Ghz, it is very popular for RC car because the receiver and controller don’t need a long antenna like it used to be. I prefer 3 Channels or more in case you want to add LED light and other stuff.
Steering Servo: This hardware determines how your RC car is turning. A good servo will not make too much noise during idle and be able to handle the load with quick response.
Chassis: This is depending on your taste of RC structure. There are plenty of good ones and some will even have the aluminum upgrade parts. We also developing an M-Drift 1 Chassis prototype for RC Drift car. You can download 3D print files for free if you want to print out 3D parts yourself. Otherwise, you can get the Kit version at our eBay Store.
Wheels: This isn’t in the picture but the car won’t run without one. For Drift Car, you would use a set of drift tires for smooth surface track or floor. You can change it back to on-road tire if you just play for speed on a rougher surface track.
Now that you have a grim of how electric rc works, you can start looking for your favorite spec that fit for your play area. Whether drifting, driving, crawling, bashing, or tracking. There are tons of brands and prices to choose from.
