Children, especially boys, get a great deal of joy when they are given a model car that they can move around on the floor and drive. It would be a special experience, however, if you built a remote-controlled car for your offspring yourself.
What you need:
- 1 battery powered model car
- 1 speed controller
- 1 servo
- 1 recipient
- 4 batteries
- enameled copper wire
- 1 remote control
- soldering iron
As everyone knows, remote control cars can do things that cannot be done manually. The children have also recognized this and are therefore very wild about such. If you want to build a remote-controlled car yourself, you don’t have to resort to kits. If you have some electronics and mechanical experience, you can even convert your child’s existing battery-powered vehicle into one. If your offspring is then also involved in the construction, he can also learn something.
Preparations for a remote controlled car
- In order to be able to build the car yourself, first lay out all the necessary parts.
- Before you start building, you should disassemble the existing model car and remove the unnecessary wires and reed switch.
- Only now can you start the conversion for a remote-controlled car.
The steps to build the car yourself
- If you want to build a remote control car yourself, you should first install the receiver, if possible in the front part of the vehicle. But of course it also works elsewhere.
- Where the battery compartment was, the 4 batteries are now connected together and then housed in this compartment.
- Now the servo (combination of control and drive unit) is installed. In order to make direct linkage possible, this should be installed behind the steering. Now a slot is milled into the servo horn. This serves as a guide for the steering pin.
- Now you still need a speed controller, which is used to suppress interference from the motor. For this purpose, two matching coils are made, which are wrapped with enameled copper wire. These are then soldered to both motor outputs of the built-in speed controller.
- Now the speed controller, servo, charging socket, switch and battery are only connected to the receiver. You should only make sure that the servo and the speed controller get their power directly from the batteries and not from the receiver.
