Introduction
This Upgrade was required as the Rock Crawler is going to be the chassis of my Autonomous (Arduino Controlled) RC Car. Also I wanted better control and build a robot project which uses an Arduino.
Research on the internet gave me some insight to the drawbacks of this modal of RC car. It's main fault was it's lack of turning circle and limited amount of lock between turns, so unable to make sharp turns. It's good points where good off-road performance, 4 wheel drive also it's articulation of each front and rear axle.
I had used the car before I took out the PCB which controlled Steering, direction and the speed and indeed it did have poor steering control; Something this instructable is going to address.
Please note : All the pictures used in instructable, show the modifications carried out on the original modal. By looking at the original model you should be able to workout which bits need to be removed to obtain the picture above.
