We began by taking a spin to our local hobby store and picking up a tamiya twin motor gearbox (the dual motor torque engine) as well as a simple 1:28 size toy car (mainly for it's front wheel turning mechanism). Then we brought everything home and quite simply ripped the toy car in half. And then, the real work started. We put the motor together using easy to follow instructions... in japanese. Then we set it up onto the back of the toy car. After the motor was properly balanced, we hooked up the wires to the motors by soldering them on (remember kids ask your parents before doing anything like that!) and the engine was locked into place. Then came the problem of putting the body back onto the car. We fixed this by breaking a hole in the back of the car and filing the outer edges to fit the motor. Last but not least, we painted the body because we decided yellow was a bit too flashy. After all of that hard work, It felt good to see our little monster working like a charm :)
