Electric motor vs. combustion engine
There are two different types of RC motors: electric motors and combustion engines. The advantages of the electric motor are that it is cheaper, “cleaner”, requires less maintenance and accelerates faster. A negative point to mention is the relatively short travel time as they are powered by batteries. This also involves waiting time until the batteries are charged again. The combustion engines score points for their longer running time and the more authentic sound. The weak points are the more expensive purchase price of the vehicle and the fact that fuel has to be purchased for it. Combustion engines are only partially suitable for beginners, as they generally drive faster and are more difficult to control.
Electric motors and controllers
The electric motors differ in brushless and brushed. There is a separate controller for each of the two motor types. Without a controller, the engine would either not move or would give full throttle when turned on. Brushed motors, also known as brush motors, and controllers are cheap to buy, but are also less powerful and don't last as long. Brushless motors, on the other hand, are very powerful, efficient, fast and have a long service life. While brushless motors and the associated controllers have no real expiration date, the brushed equivalents wear out on the carbons and armatures depending on use and use. You can visually recognize the brushless motor by its closed motor housing and the three outgoing cables, whereas the brush motor has ventilation holes and only two motor cables.
Upgrade using a programming card
If you want to buy a brushless motor, you have a few options. First, you should decide on a brand. If you want to upgrade, consider purchasing a brushless motor, brushless controller, and programming card combo. The programming card is a useful accessory that makes the settings easier and allows you to easily change your preferences.
Motor power
The power of the brushless motors is marked with a four-digit number followed by “kV” and a single-digit number followed by “T”. KV stands for the number of revolutions per minute per volt. The larger this number, the faster the vehicle travels. If your car is to be used off-road, it is important that you choose an engine with the correct “T”, “T” should be higher and “kV” lower, if you use your vehicle on the road it is the other way around. This information means: the lower T, the higher the final speed and, conversely, the more force. For example, with a 6000kv brushless motor you need 5.5T to 8T for on-road and at least 8.5T for off-road. A 4000kV motor with 8.5T is suitable for off-roading and reaches around 55km/h.
