Hi! Our names are Jason and Bryan. This is a continuation of our fourth Lego project, the Remote Control Car. The final form of our car was a four motor powered one. It was difficult to do it but it was worth it. This is how we built it. First we got two more motors, then we plugged them in. They had to share the same plug because there was only one left. Then we programmed it. It was diffcult because the car was all messed up. Its controls were all messed up. We tried to fix it but it was still the same. We changed the procedures but it still didn't work. I'm not sure what I did but I fixed it. Because of the four motors, the car turns a lot better and doesn't turn a lot when it goes forward. We then decided to try it out on the straight away course. If you don't remember it was a straight race to touch a piece of tape. We had trouble but we beat our time of 12 seconds. Now the best is 11 seconds. I hope this is the last time we modify and race it.
Below is a picture of the the four powered motor car, and the procedures.
