Low Cost RC Car

I wanted to make a low cost rc car, using the 27mhz transmitter and receiver, I have also attached a video so you can watch it if you don't want to read this entire page

1. 2 x 18650 batteries
2. 2 x Single channel battery holders
3. Flat DC Motor
4. Normal DC motor
5. A 27mhz transmitter module
6. A 27mhz receiver module
7. TP4056 charging module
8. Cardboard
9. Wires and push connectors (optional- can be directly connected or soldered instead)
10. Straw
11. Gears
12. Any 2 x aluminium or a steel rod for the axle of the car
13. A DPDT 6 pin Slideswitch
14. 4 wheels

The Circuit Diagram is attached, follow the circuit diagram and connect all your components.

Stick all the components to the cardboard and then adjust the gears as per required for your cardboard and your car. Also make sure to use small gears for the flat dc motor's shaft and big gears for the shaft of the steering system. This will increase the toque and reduce speed which will help in turning the car. Similarly use a big gear for the shaft of the back pair of the wheels in order to increase the torque
