Hello Experts,

I've got problem with my project. I want to create a car which can stand on the rear wheels. I've tried for a long time but I'm stuck and I decided to ask you for help...

Firstly I want to run my car - using all wheels - and it's my main problem

Unfortunately I have no idea how can I connect all of this parts.

I made a photo - SABERTOOTH V1.03

I connected wires (red circle, 1st picture) with motors(blue circles, 2nd picture):

My car doesn't run (all of wheels are blocked when connected to battery).

Any ideas?

Thanks in advance

I read the post with interest and my minds eye was thinking of some one doing wheelie in a car like I have seen done on a motorbike. I have seen this done but he had independent breaks on each rear wheel to be able to steer.
Then I saw the photos and realised it was a toy. I looked up and found some info here http://www.solarbotics.com/resources/documentation/ however not exactly the same as you have.
I remember trying to build a better controller for my model railway after finding the specials made to allow one fine control would destroy the permanent magnets in the older motors think I used consent voltage rather than plain variable resistor.
My point being the motors and drive must be compatible.
Likely to fault find you will need a meter of some type may be even a computer interface but I would think there are sites out there where others are doing same thing.
I would start by buying a model book and looking for a forum run by people into building models.

If you don't want high speed, you could try using stepper motors, these would allow precise control of each wheel.
