Radio control cars- Generalities about mechanical drives

You should consider buying radio control cars. They have many pros when analyzed in comparison to other models. For instance, they have an advantage over mechanical drives in which if the batteries run out too there will be enough current to drive the servo and receiver may be the drive in a position other than neutral so the car moving on without control.

As for connecting the radio control cars drive, they will be connected with two wires to the battery with two wires to the motor and another set of 3 wires go to channel 2 receptor. On some drives the positive lead of the motor and the battery will drive the same wire as the positive pole is shared. Another cable can be used to feed a fast FET servo if you have installed in our car and finally another two are used to bypass the internal regulator if we use 4 or 5 elements of battery (1.2 volts each). You can learn how to drive it in no time.

Its operating frequency is outstanding. The first electronic inverters working at low frequencies (50-60 Hz) but the current can exceed 7000 Hz this means that they can cut and supply the current much faster. The higher the operating frequency the greater radio control cars running smoothness.

The performance of the drive will depend on the quality and number of transistors. Transistors are typically mounted in parallel (on models with brake but not reverse, the most commonly used in competition) and the higher the number the lower the total resistance so that the drive consumes less power and less but also overheat its price will be higher.

Some radio control cars incorporate temperature protection against overheating in case of power cut stopping the vehicle until this fall. They can also come with reverse polarity protected if the battery connectors in use that do not distinguish the position of insertion. This protection can be achieved by a fuse or by a circuit that protects the transistors. Reversing the polarity of a drive even with the current switchgear (the car) can be burned off transistors especially those involved in the operation of the brake.

High-end drives incorporate the possibility of limiting the current (between 20 and 120A). Limiting the current to save energy and above certain values, the motor receives full advantage. Acceleration is lost but can make driving less critical accelerations as strong without something interesting especially when you're a novice. Stick to basic radio control cars models. You will simply love them!
