Basic knowledge of RC car for hobbyists (part 1)

Electronic equipment:

1. Electronic governor: divided into brush and brushless, the role is to control the motor power current, and to supply power to the receiver and steering gear.

2. Receiver: used to receive the transmitter signal and assigned to the electronic governor and steering gear, commonly has 2-channel, 3-channel, 4-channel, 6-channel and so on. In general, the receiver also has a BATT channel, this channel is not controlled by the receiver, and in a normally open state, can be used by external fans or LED lights.

3. Motor: Brush motor and brushless motor

4. Steering gear: change the electrical energy into a range of kinetic energy can produce a certain angle. According to the strength, the general size is 3KG, 9KG, 11KG and so on.

5. Battery: A storage device used to provide power. There are nickel-cadmium batteries, nickel-metal hydride batteries, lithium polymer batteries, etc., now the most commonly used is the nickel-metal hydride batteries and polymer batteries.

When you choose the accessories for HPI RC cars, remember to choose carefully for the high-quality one that can be used for a long time.

What is brush and brushless?

1. Brush motor is more common. Because of the low cost, good stability, good low-speed linear, it’s the first choice for low-end novice cars, drift cars, and climbing cars. But there are obvious shortcomings - high temperature, brush wear, normal speed and acceleration ability, shorter life.

2. In the match with the corresponding brushless sensitive EG and brushless senseless EG, in the same power, the brushless motor speed is higher than the brush motor, has faster acceleration and basically no wear, so it’s suitable for high-speed RC sprint car. Because the size is similar, the brush one can be upgraded to the brushless one. And nowadays, we can find more and more RC cars cheap brushless motor.

Sensitive and senseless

As for the sensitive and senseless, the principle will not be explained in detail, as a novice, you only need to know that the sensitive one has slightly better low-speed linear and throttle response. On the market, the senseless motor can be used in off-road cars, small trucks. It’s recommended to use brush equipment for the climb car.

Even though the RC truck car has no strict requirements for high speed, but high-quality RC truck parts for maintenance and replacement is also important.
