This is my first instructable, be kind =3
Now my RC CAR has a proportional acceleration system, it works for backwards and forwards. See it on Step 5
The final result is here:
Step 1: Material list
- A structure (sorry, I didn't took any photos of me making it). Mine includes a steering bar in the front with 2 wheels and the car motor on the back with 1 wheel.
- 2 hobby servos, one for steering (self explanatory) and one for acceleration (you'll see the magic very soon).
- A micro switch.
- 5V regulator for the receiver.
- 3S 2200mAh LiPo
- Instant glue
- Duct tape
You will also need creativity =]
Step 2: Fixing the structure
If you build the same way I did, you can either do this or lower the center gravity of your car by placing the battery on the bottom of the car.
Step 3: Putting things together
*Note: 5v regulator circuit is 5th picture
1- tape the cables to the battery
2- plug the regulator and the alarm in the battery
3- Now, Tape the receiver (radio Rx) to the battery, don't forget to tape the antenna tube too
It should look like the 3 picture.
Now glue the steering servo in the right place. Since it's a steering system, the center of the servo arm should be placed on the same line that the front wheels are placed. You can also carve a little space on the servo arm so the steering bar pin can slide in it. This will happen mostly because the servo is not centered perfectly.
